Painting a car is a complex technological process that puts forward strict requirements for the quality of the materials used. painting works automotive paint is diluted with a solvent and brought to the desired consistency and viscosity. We will talk about how to properly dilute the paint in this article.
There are several ways to dilute paint.

You will learn what types of paint are used to paint a car and how they are diluted. We will consider in detail solvents for automotive paints, their varieties and application technology.

car paint

Upon completion of the preparation of the car body for painting (alignment of deformations, puttying and grinding), microcracks that are indistinguishable to the naked eye remain on its surface. In order for the composition used for painting to fill the microcracks, the painter is forced, thereby reducing its viscosity and density. By diluting the paint for cars on the surface to be treated, covering it with a thin even layer.

All types of car paints consist of three basic components:

1. Pigment - a powdered substance that gives the composition the desired color;
2. A binding base that holds the pigment in itself and ensures the adhesion of the material and the surface to be painted;
3. Solvent, due to which the composition is given the original consistency.

Different types of paints differ in their physical properties - density, elasticity, degree of fullness and hardness after drying.

Based chemical composition binding base, materials are classified into three groups:

• Alkyd;
• Acrylic;
• Melamine alkyd.

Alkyd compounds are made on the basis of alkyd resin - an oily synthetic substance. This is a one-component material that requires opening with a layer of varnish after application. All alkyds dry at standard atmospheric temperatures.

To the benefits alkyd compounds applies to:

• Fast drying;
• Wear resistance and preservation of the original color under the influence sun rays.

melamino alkyd enamels- the most commonly used spray gun paint for professional car painting in special boxes. Its polymerization occurs at elevated temperatures (120-130 degrees),

The color number of the factory paint of the machine can be found in the documents for it.

Advantages of melamine alkyd - wide color palette(compositions with the effect of mother-of-pearl, metallic, matte enamels) and the quality of the final coating. Disadvantages - material consumption (3 layers required) and impossibility of application in garage conditions.

Alkyd enamels - three-component compositions, after drying (at room temperature) forming glossy surface, which does not require additional varnishing. Such compositions are applied in 2-3 layers, while they dry faster than other materials.

How to dilute paint for an airbrush

Thinner for automotive paint is added by the manufacturer to the original composition so that the material does not dry out during storage. Before painting the car, you need to dilute the paint yourself, giving it the required viscosity.

Choosing what to dilute car paint, consider temperature regime, at which the polymerization of the material will occur (the painted surface dries out after the solvent contained in the composition evaporates from it).

According to this parameter, solvents for paints are classified into:

• Fast, used for dyeing at low temperatures;
• Slow - they dilute enamels that dry out at elevated temperatures (such compositions provide uniform polymerization and, as a result, best quality coatings);
• Universal - for paints that dry at room temperature.

Factory enamel contains a solvent in its composition and the proportions in which you need to dilute the material depend on its initial concentration, adjusting the viscosity of the paint. Based on the initial ratio of components, the materials are divided into:

• LS - low-filled;
• MS - medium filled;
• HS, UHS, VHS - highly filled.

Depending on the initial fullness of the composition, the percentage ratio of the volume of enamel indicated by the manufacturer and the solvent added to it when diluted will differ.

The solvent for automotive paint used in the preparation of the composition must correspond to the type of solvent added by the manufacturer to the material initially (information about it is indicated on the package).

Before self painting consult with a specialist

There are polar and non-polar solvents that differ in chemical composition:

• Polar solvents consist of molecules of the hydroxyl group - alcohols and ketones;
• Non-polar - from hydrocarbons of the liquid type (these include White Spirit and kerosene).

A paint having a polar composition will reject the added non-polar solvent, and vice versa. Water emulsion and acrylic materials, as a rule, are kneaded by the manufacturer on non-polar solvents, alkyd and melamine-alkyd - on non-polar. Universal is a xylene-based solvent that interacts with all formulations.

To avoid problems with incomparability of components, we recommend purchasing materials from the same factory batch or using solvents recommended by the manufacturer, indicated on the instructions for the composition.

Consider the most common types of solvents and their scope:

1. No. 646 (polar) - extremely aggressive agent, used to clean spray guns after painting work, is not used to dilute the paint (with the exception of acrylic compounds);
2. No. 647 (polar) - used to dilute nitro paints and nitro varnishes;
3. No. 650 (polar) - applicable to most paints and varnishes, universal;
4. P-4 (polar) - used for alkyd enamels.
5. White spirit (non-polar) - dilutes alkyd and oil enamels.

It is convenient to use a spray gun for applying paint

The prepared paint is poured into the viscometer, after which the time is calculated for which the composition flows out through its holes. The seconds received are measuring value paint viscosity.

When painting cars, DIN4 viscometers are used, with a hole diameter of 4 mm. (there are products with a diameter of 2.6 and 8 mm). The viscosity test is carried out at a 20-degree temperature.

The normative viscosity for different types of paints is different:

• Acrylic compounds - 19-20 sec;
• Melamine-alkyd and alkyd enamels - 15-17 sec;
• Primers - 20-21 sec;
• Oil formulations - 20-22 sec.

It is necessary to dilute to a viscosity of 18-20 seconds. If the measurement showed an increased viscosity, it will be necessary to dilute the varnish or paint with an additional portion of the solvent, and vice versa.

To prepare the composition, measuring containers and special rulers are used, on the surface of which the divisions of the proportions of the components (4:1, 2:1, etc.) are applied.

When diluting one-component compositions (alkyd and melamine-alkyd enamels, 1K primers), only a solvent is added to the material, but if you work with a two-component composition (2K primer, acrylic enamels), initially a hardener is added to the paint (according to the proportion indicated in the instructions) and only then the mixture is given the required viscosity with a solvent.

During the mixing process, dust and mechanical particles can enter the composition, which can clog the nozzle of the spray gun, or, if it is not equipped with a built-in filter, end up on the surface to be painted. Before pouring the material into the working container of the spray gun, filter or fill the paint through a nylon stocking that covers the neck of the spray gun container.

How much paint do you need to paint a car

The following factors affect the amount of material spent when painting a car:

• Dimensions of the painted surface of the body;
• Number of coating layers;
• Color of the material (to obtain the depth of some shades, it is required to apply more than 3 standard layers);
• The viscosity of the composition;
• Matching primer and base coat colors;
• Design features of the spray gun used for painting.

Average calculations show that it takes 150-200 ml to paint one door or wing. enamels, for one bumper - 200-250 ml., hood - 500 - 600 ml. If we talk about costs by area, then 250-300 ml are needed per 1 m 2 of surface. paints.

WATCH THE VIDEO INSTRUCTIONS

Consumption also depends on the covering ability of the material: for acrylic compositions it is high, for painting the body of a medium-sized sedan it takes 2-2.5 liters, for alkyd and melamine-alkyd enamels it will take about 3 liters. enamel.

The above volumes are given without taking into account the solvent - after diluting the paint, the working volume of the material increases.

The process of painting a car body is a rather complex technological process with strict requirements for the quality of the materials used. And before you start painting work, it is necessary to dilute the coloring composition to the required consistency and viscosity - without this, it is very, very difficult to obtain a high-quality result. Let's see, how to dilute car paint.

When preparatory work finished on the body, microcracks still remain on the surface, not visible to the eye. It is necessary to dilute the paint so that it can fill all the cracks and microcavities. The dilution process allows you to reduce the viscosity of the composition and density. Due to dilution, the dye lies better on the surface in a thin and uniform layer.

Also from physical properties one or another coloring composition depends on the specifics of the work. If an airbrush will be used as the main working tool, then it is necessary to dilute the paint for painting the car to a liquid state. So the coloring material will pass better through the spray nozzle. When working with a brush, the viscosity of the paint should be lower.

Also, the composition must dry quickly so that smudges and other defects do not appear on the body. To minimize purchase costs necessary materials and at the same time not to lose the quality of the painting, you need to know how to properly dilute the paint, depending on its composition.

Composition of car paints

All automotive paints and enamels are composed of three basic components:

• pigment - a powder substance that gives the paint the desired color;
• bonding base- it holds the pigment and ensures the adhesion of the material to the surface;
• solvent - with the help of it, the composition is given the necessary consistency.

Different types of dyes have different physical characteristics- elasticity, density, degree of fullness, hardness of the layer after drying.

Solvent types

Any car enamel is sold in the form of a liquid, but this does not mean that it can be applied immediately. The manufacturer has already added a solvent to the paint, but just enough so that the composition does not dry out. To obtain a uniform coating, the material should be further diluted. This coating will protect the body from damage and corrosion.

Before mixing paint with a solvent, you need to remember that the manufacturer has already added a certain amount of it. Depending on this, coloring compositions are divided into:

• highly filled;
• medium-filled;
• low-filled.

Fullness is a property that determines the volatility and viscosity of the enamel, it helps to understand how much solvent can be added.

According to the rate of evaporation

Solvents, like paints, are different, consider their main types. Depending on the rate of evaporation, the following compositions are distinguished:

• Slow - they are used for work in summer period time or at high temperatures.

• Fast - the components in the composition accelerate the drying process and make it possible to work with the material even in winter.

• Universal - are allowed for use at medium temperature conditions.

According to physical and chemical indicators

depending on the physical and chemical characteristics There are two groups of solvents:

• Polar - alcohol, ketones, substances with molecules of the hydroxyl group. These materials are suitable for working with acrylic paints.

• Non-polar - white spirit, kerosene, a complex of compounds based on hydrocarbons.

In order to determine exactly how to dilute a particular paint, you should find out which solvent the manufacturer used. Match polar to polar or non-polar to non-polar.

How to properly dilute the paint

The manufacturer indicates how much solvent to add to the desired consistency on the packaging. For example, in the case of using acrylic, which already contains a certain proportion of the activator, solvents are added in a minimal amount - the proportion is 10-15% of total paints.

How to dilute the paint if it is a two-component composition? Many people use the following proportions - for 1 liter of paint, 0.5 liters of solvent and 150 ml of hardener are used. How correctly the proportion is observed, the quality of the result will be.

In order for the paint to be prepared correctly, experts recommend using a measuring ruler or flask. This is necessary so that the proportions of the coloring composition, hardener and solvent are fully consistent with those recommended by the manufacturer.

You should also get the correct viscosity of the diluted mixture - it is determined using a viscometer. You can also determine the viscosity by eye - the liquid should drip, and not flow in a jet.

Also, the viscosity varies according to how and what the coloring will be done. So, for spray guns with a small nozzle, it is necessary that the coloring composition be liquid, and for working with a brush or roller, you can make the dye thicker.

Experts recommend that the mixing container has a strictly cylindrical shape. This is the only way to evenly mix all the components and measure the amount correctly. Measuring utensils are best suited - a plastic jar with a lid. It has markup that allows you to mix components in different proportions. The base is poured into the dishes to the required division, and then a hardener or solvent is added there. With a measuring ruler, the components are conveniently mixed - the paint is diluted.

Often a measuring ruler is sold along with paint, and cans of famous brands always have proportions for these rulers.

On the video: how easy it is to dilute the paint.

50% hardeners and up to 20% solvent are added to the two-component composition. The degree of dilution of the base enamel can range from 50% to 80%. How to dilute the paint exactly, it is better to look at the instructions.

They differ from traditional metallic paints by the presence of aluminum powder in the composition. These are car enamels, which consist of binder, pigment, solvent, as well as small metal particles. The paint should be applied in a thin and even layer - for this it must be liquid. Let's see how to dilute metallic paint.

Most often, the following proportion of solvents and coloring compounds is used - 1: 1. But it depends on how the latter are applied. First of all, the surface is painted with a dry layer - for this, 2 parts of the dye and 1 part of the solvent should be prepared. Then a second thick layer is applied in the main ratio of 1 to 1. After drying, another similar layer is applied, but thinner.

To paint a car with high quality, you need to choose the right dye and color. There are a lot of colors - for every taste, but we already know how to breed them correctly. Therefore, a quality result is guaranteed.

Various solvents (23 photos)

Cocktails are different, and not all of them are designed to be taken "on the chest." Paints and varnishes that we use for restoration paintwork car, are, in fact, also cocktails - properly prepared mixtures of several ingredients. And since we strive to ensure that the restored car (wing, door) after repair sparkles brighter than the new one, and the paint lies evenly, then our “paint cocktail” should be prepared competently, with sense and arrangement, and not concocted anyhow.

Today you will know

Ingredients

First of all, let's decide on the type of our "paint cocktail": whether it will be ordinary acrylic enamel (which is less likely), or metallic or mother-of-pearl type paint (most likely).

Conventional acrylic enamel - two-component, with a hardener. The “ingredient kit” for such materials consists of three jars. For example, a liter of paint, half a liter of hardener and 100-150 ml of thinner. That is, when buying a liter of paint, you actually get about 1.6-1.7 liters of diluted paint.

In the case of “metallic”, the base paint is necessarily coated on top with a transparent varnish - without it, spectacular coatings look nondescript, and the weather resistance of two-layer coatings is much higher. Transparent varnish, as well as acrylic enamel - two-component, with a hardener. But the “base” does not need a hardener - it is one-component.

Thus, the “kit” for two-layer coatings already consists of five cans. For example, a liter of "base", 500-700 ml of thinner for it, a liter of clear top coat, half a liter of hardener and 100-150 ml of thinner for varnish - only 3.3 liters! At the same time, the most diluted paint was no more, the same 1.7 liters.

Making kneading

Before filling the gun, mix the components of the purchased paint.

For the correct mixing of the components, which results in a coating material of the required viscosity, the following conditions must be met.

Tableware

It is important that the container in which we mix is ​​strictly cylindrical shape(flat bottom and vertical walls). Only in such a container can you evenly mix the components and correctly measure their quantity.

It is better if it is a special measuring utensil in the form of a transparent plastic jar with lid. Such cans are marked, which allows mixing materials in the required volume ratio (1:1, 2:1, 3:1, 4:1, 5:1, etc.).

Measuring containers are produced in different volumes, ranging from 100 ml to almost half a bucket

Also, for dosing and mixing paintwork materials, it is convenient to use a special ruler with marks that determines the volume fractions of the components.

Pour the base into a cylindrical dish to a certain division, and then add the hardener (if added), then the solvent to the desired mark. All mixed with the same ruler - and you're done. Often a measuring ruler is sold along with a paint kit, and on all branded cans the proportions are indicated according to these rulers.

It is convenient to measure the required number of components using measuring ruler. Then he chatted with the same ruler - and you're done.

Proportions

With the abundance that has reigned in the paint and varnish market, it is impossible by definition to give, as they say, one recipe for all occasions. Yes, and you don't have to. There is TDS - you know the rest from whom.

However, it would be helpful to provide some general guidelines. In principle, we have already talked about them a little higher: two-component products usually add up to 50% hardener and 10-20% thinner. The degree of dilution of base enamels varies, as a rule, in the range of 50-80%. Well, see the exact proportions already in the instructions for a specific product: all canned varnishes and enamels have indications in the form of pictograms that inform you in what proportion you need to dilute the paint with a hardener (if the material is two-component) and thinner.

We remind you: in one-component materials (alkyds, base enamels, 1K primers), only thinner is added; in two-component materials (acrylic enamels and varnishes, 2K primers), a hardener is first added, then the mixture is brought to the desired viscosity with a thinner.

If you order paint for selection in the laboratory, then you will be given a set of components (usually ordered as a set), mixing which you will get a ready-to-use material with a working viscosity - as they say, “under the spray”. Or they will give out already diluted paint (naturally, this only applies to the base, since the life time of two-component materials after mixing is strictly limited).

Additives

A description of the recipes for preparing paint and varnish cocktails would be incomplete without mentioning additives - materials used to change individual characteristics of enamels, varnishes or primers.

For example, to create a rough surface - very often they are painted like this plastic bumpers SUVs - there are structural additives of varying degrees of graininess. And in general, so that the paint on the plastic does not crack, 20-40% of the plasticizer is necessarily added to it. There are matt elastifiers designed to reduce the gloss and coloration of plastic parts such as Mercedes-Benz side trims.

When painting with spectacular two-layer coatings, these additives must be mixed with the top coat (it is recommended to add a plasticizer to the filler primer as well). Read more about supplements and their use.

We measure viscosity

Any painter should be able to control such a vital important indicator like viscosity. What for? to match the recommended value. Again, why? To evenly apply the material to the surface, and obtain a coating of the required thickness with the planned properties - beautiful and durable.

"Viscosity" (from lat. viscosus - sticky, sticky) - a value that characterizes the fluidity of a liquid.

What for?

Filtering

Cooked paint material before refueling into the spray gun tank, it must be filtered without fail, as it may contain foreign inclusions that got there during the cooking process, clots, etc. Otherwise, guarantee receipt quality surface it is impossible, because all this debris may eventually end up on the painted surface.

For filtration, it is convenient to use disposable paper funnels with a filtering nylon insert (mesh size, as a rule, 190 microns). I inserted the funnel directly into the tank, strained it - it's ready, you can paint!

We fill the paint tank only with the use of a filter funnel

Basic Mistakes

Achieve steadily High Quality work performed is possible only if technological recommendations on the use of certain materials. There is simply no other way for those who want to repair modern cars and repair them with high quality.

Meanwhile, ignoring technological requirements remains the main (!) Cause of defects and errors. As the saying goes, "... so many times they told the world" ...

But “free morals” have always been and will be: we adjust the airbrush “by ear”, we mix the paint “by eye”, we forget about strictly defined “lifetimes” of products prepared for use.

For example, in an hour, the varnish changes viscosity by an average of 100%. He thickens. Before lunch, we stirred it, measured the viscosity - 20, satisfied we left for a meal, we return in 50 minutes, and he already has all 40! Of course, the material can no longer be used. But how often does anyone consider such a "trifle"?

How often does anyone remember that the material into which we did not add the hardener will no longer be able to properly harden, no matter how dry it is. Acrylic two-component materials, after all, are cured: due to chemical reaction between an acrylic binder (base) and a substance for crosslinking molecules - polyisocyanate (hardener). And only the manufacturer of paintwork materials can know how many -N=C=O units (present in the hardener) are necessary to react with a certain amount of OH units (which are part of the base) and turn the material into a strong polymer film (more on this).

So it turns out that if we pour not enough hardener, there is simply not enough crosslinking material for the correct curing of the film. The coating is soft, uncured.

The opposite situation - with an excess of hardener (and, accordingly, an excess of -N=C=O units) has the opposite effect - the coating turns out to be too hard, but at the same time inelastic, highly prone to peeling, cracking, and chipping.

So if it is written on a can of varnish to dilute in a ratio of 2: 1, then you should not be too lazy to measure strictly two parts of varnish and one part of hardener. No more, no less.

Correct polymerization of two-component materials is only possible if the correct mixing ratio with the hardener is observed.

Well, the fact that acrylic materials can only be cured with original hardeners is generally not subject to discussion. In acrylic systems, copolymer and polyisocyanate are carefully matched to each other, and if we take a hardener from another varnish or another manufacturer, we get another polymer with completely different properties.

The jar with the remains of the hardener must be tightly closed, as the hardener reacts with air moisture, resulting in its turbidity and precipitation of crystals, sometimes gelation. To prevent air from entering the partially used can of hardener, it is recommended to turn it upside down and place it on the lid, and store it in this position.

Enamel ML-12

Brief information about the use of enamel ML-12

Enamel ML-12 is used for painting products with a metal surface, which are operated both indoors and under various atmospheric conditions. The surface can be pre-treated with a primer only, or treated with both a primer and putty.

Appointment Details

The main purpose of ML 12 enamel is to paint cars that have either been simply treated with a primer beforehand, or putty material has also been applied over the primer. In addition, enamel is perfect for other products that are used when working indoors and in various atmospheric conditions.

ML-12 enamels are used not only for decorative painting, to give an aesthetic appearance to the product, but also to protect it or repair small, minor defects in the original paintwork of mopeds, bicycles, cars, motorcycles, metal garages, agricultural machinery and equipment.

If you prefer a different color enamel, it can be made to order.

Main purpose

Enamel ML-12 is used for coloring metal surfaces, which will be operated inside the house and outside it. Bases and products may be exposed to precipitation. However, they must first be primed, and additionally can be covered with putty.

Specifications

Enamel ML-12 forms a film, which should be homogeneous, It should not have extra inclusions, pockmarks and wrinkles. However, shagreen is acceptable. The color of the film must be within the tolerances set by the samples. The rest correspond to the sample number.

Professionals are often interested in conditional viscosity, it can vary from 70 to 120 s. As for the gloss of the film, it is equal to 58%. Whereas for protective shades this value varies from 35 to 45%.

The mass fraction of non-volatile substances varies from 44 to 60%. The final value depends on the color, as well as the degree of grinding. This parameter for enamel ML-12 can be equal to the limit from 10 to 15 microns. Flexural elasticity of the film is 3 mm. The hiding power of the dried enamel layer, depending on the color, can vary from 35 to 100 g/m². But if you buy paint in the color white night, then for it the hiding power will be 60 g / m². The strength of the film when tested using the U-1 device is 45 cm.

Additional Specifications

Quite often, professionals pay attention to the hardness of the film on a pendulum device. If type M-3 is used, then the hardness will be 0.5 so. Whereas for the pendulum A of the TML type, the hardness is 0.3. Adhesion coating - 1 point, but no more. You may also be interested in the conditional light fastness of the mixture after drying, it is 4 hours or less.

Consumption and application features

Enamel ML-12, specifications which were mentioned above, can be used for application to agricultural machinery and truck bodies. You can dilute the mixture with the following solvents:

• solvent;
• xylene;
• solvents grades 651 and RKB-1.

When preparing in the priming process, the compositions GF-0119, GF-021 are used. Application is carried out on a dried primer in 2 layers. Intermediate drying should be approximately 7 minutes, which is true at an ambient temperature of 20 °C. You can use a paint sprayer for application. Usually 2 coats are applied.

Consumers are often interested in the consumption of ML-12 enamel. For each square meter with a single coat, you will spend approximately 80 g. Depending on the type of surface, this value can be increased to 100 g per square meter. The surface to be painted during the preparation process must be cleaned of rust, dirt, and dust. The base is degreased. If you have to work with the old coating, then the surface is additionally polished. After the primer is applied. You can use one of the above compositions for this.

Application features

Before use, the enamel must be mixed well and diluted with a solvent up to 25% by weight of the base material. Application is carried out in two layers. If you have to work with the old coating, then the number of layers must be increased to 2. The second layer must be kept for about 30 minutes at a surface temperature of 130 °C.

Enamel consumption varies depending on the complexity of the product to be painted and the thickness of the formed layer. In order for ML-12 melamine enamel to be preserved for a long time in a closed container, it must be stored, protected from sunlight and moisture, and kept away from heat sources.

What else you need to know about enamel

The described enamel is suitable for application to different surfaces and products, it can be:

• moto;
• auto-;
• bicycle technology.

The surfaces to be coated can be used with different conditions. After drying, a homogeneous film is formed on the base without delamination and foreign inclusions. ML-12 enamel, the characteristics of which were mentioned above, is sold in industrial containers, its volume starts from 18 kg.

Enamel manufacturers

On the market, the enamel described in the article is offered by different manufacturers. Among others, Regionsnab should be singled out. This company is located in Moscow and supplies enamel in 50 kg containers. You can buy a kilogram of products for 120 rubles. She offers to find lower prices, then the goods are delivered at a reduced cost.

Another manufacturer, Khimprom-m, offers to purchase enamel for 135 rubles. per kilogram. This company positions its products as automotive paint. Experts recommend using it for decorative and protective painting of metal surfaces. With the help of this composition, according to company representatives, it is possible to correct minor damage to automotive coatings, elements of industrial and other equipment, as well as bicycles.

Another manufacturer of ML-12 enamel is the Chelyabinsk Paint and Varnish Plant. He supplies enamel, advising to carry out its hot drying. The manufacturer recommends adjusting the working viscosity with xylene. If necessary, the enamel can be filtered through a mesh. In the cold season, the material is heated to a positive temperature before use.

You can also buy enamel of the described brand at the Yaroslavl Paint and Varnish Company. The supplier provides a warranty period for the storage of the material for 12 to 24 months, which will depend on the volume of the container. The manufacturer emphasizes that the conditional viscosity during long-term storage can be increased.
