What glue to glue polyethylene with. What glue to choose for polyethylene and how to use it correctly? How to glue polyethylene sheets

Greetings! In articles about insulation, the use of penofol is constantly recommended, but I had a question, how to glue penofol to concrete, for example, if I am using a non-self-adhesive option? Thank you.

Hello. We will try to answer your question.

Penofol is an energy-saving material with a layered structure. It combines the properties of foamed polyethylene and thin aluminum foil. The material is characterized by lightness and low thickness, and therefore is often used on various objects (including balconies) for insulation, ensuring tightness, thermal, noise, vapor and waterproofing. However, to ensure high-quality protection, it is not enough to lean penofol against the insulated surface - you will need special glue for penofol.

Features of adhesive installation of penofol

Adhesive for foil foam foam allows you to quickly complete work on insulating surfaces. In addition, the adhesive installation method is easy to implement and low-cost, since it does not require any special skills or specialized tools.

Usually, when choosing gluing as a method of installing insulating surfaces, you need to take into account the load-bearing capacity of the adhesive layer - but when using penofol, this fact will not be decisive, since the material is incredibly light.

Rules for preparing surfaces before gluing

Correctly selected penofol adhesive is not yet a guarantee of successful work. To ensure the integrity of the connection, the main thing is that the surfaces to be glued are prepared. on them in mandatory eliminate all defects, chips, unevenness, cracks, as well as dust.

Important: Surfaces made of metal, concrete or wood can be additionally primed for better adhesion of the layers.

One of the most important conditions quality result - evenness and cleanliness of the surface. Thus, concrete floors and walls are leveled, cracks are eliminated, and metal elements treated with anti-corrosion coating.

What can be used as adhesive for penofol?

Penofol adhesive can be special or universal. For these purposes, professionals also allow the use of liquid nails, double sided tape, thin layer polyurethane foam. The choice of the type of adhesive depends on both the purpose of the surface and its further design.

It is very important here that the characteristics of the adhesive composition correspond to the performance indicators of the insulation:

  • ability to withstand operating temperatures in the range of +100…-60°C;
  • permission for indoor use;
  • biological non-toxicity;
  • adhesion resistance.

If insulation is carried out outside, on the facade, then the adhesive composition must be resistant to water vapor and water. Non-toxicity requirements are also mandatory, since the balcony belongs to residential premises. Therefore, adhesive for foiled penofol must certainly have hygienic safety certificates.

How to properly glue penofol

To correctly glue penofol, you need the selected adhesive composition Apply to the side of the material that is not protected by foil. It is important to apply the glue in an even, thin layer so that all areas of the insulation are coated, without gaps.

When coating, special attention is given to the edges of the panel so that the penofol does not begin to peel off during operation. In order to fix the insulation, the material must be kept for 5-60 seconds so that the glue applied to it dries slightly. This will ensure better adhesion of the composition. Then the prepared canvas is pressed to the surface to be pasted, held and very carefully smoothed - until it is completely fixed.

If penofol is fixed in pieces, between which there are seams, then these same seams are additionally glued.

You will need

  • - double-sided tape;
  • - soldering iron or iron;
  • - two metal plates;
  • - cotton fabric;
  • - chromic anhydride or chromium;
  • - BF-2 glue (phenolic butyral);
  • - glue for polyethylene;
  • - means personal protection.

Instructions

Connect the joints of the plastic film using double sided tape. This is the simplest and quick way attach parts made of this material to each other. However, do not expect the glued parts to withstand much stress.

Weld polyethylene - perhaps this is the most common way to join film parts. It requires caution, as during heat treatment you risk ruining the material. We can recommend three proven methods: - place both sides of the polyethylene to be glued between two metal plates so that the edges of both parts protrude slightly. Run a soldering iron over them - the metal will not curl. Also, if necessary, you can make a polyethylene patch by thermally treating the edges of the parts to be welded; - use an iron heated to maximum hot temperature. In this case, the parts should be overlapped (at least 1-1.5 cm). Place under the backing layer of the film and on top straight stripes and iron them; - you can connect the polyethylene parts by dripping molten plastic onto their joint. This way you can repair not only film, but also other plastic items.

Find the right adhesive for plastics. The vast majority of adhesives will not work for you. Some mixtures can be used, but only after preparing the surface of the plastic - it should become more active. To do this you will have to "mini-". So, after applying a solution of chromic anhydride (25%) to polyethylene, you can use BF-2 glue. You can get the specified chromium preparation in stores. chemical reagents or from familiar chemists. You can replace it with a chrome pick.

Try a special adhesive for polyethylene, such as DP 8005 (structural adhesive for plastics) or WEICON Easy-Mix PE-PP (structural adhesive for polyethylene and ). The peculiarity of such compositions is that they do not need pre-processing material. The mixture changes the structure of the polyethylene surface, after which it sticks together normally.

Please note

When repairing polyethylene, you need to work with chemicals extremely carefully - outdoors and with personal protective equipment (gloves, overalls, mask and goggles). Chromium preparations are poisonous and leave permanent stains on clothing. If you do not have the conditions to work with chemicals, it’s better not to take risks and use more gentle methods.

Oilcloth - synthetic material for wall decoration, as it looks beautiful and is quite cheap. About the technology of gluing oilcloth, about all the subtleties this process It’s worth knowing even before you decide to glue the material at home or in the country.

Instructions

In order to determine how much oilcloth you will need, take measurements of the room, that is, the number of pieces for pasting should be equal to the number of meters of wall length (you can ignore window and door openings).

If the room has been wallpapered previously, completely remove all previous coatings. If there is paint on the walls, moisten them with water and remove the plaster, plaster, paint, and then dry thoroughly.

Now take the oilcloth panels themselves and spread them with glue evenly over the entire area, without missing a single area, otherwise bubbles may form.

Many materials cannot be joined using metal fastenings, this is especially true for elastic polymers. Anyone who has encountered this procedure knows how difficult it is to choose good glue for polyethylene. Most products have very smooth surface, which provides it with poor adhesion. Therefore, you really need to find quality material who can overcome this obstacle and for many years will glue the polymer to the selected surface.

Glue composition

For connection composite materials with a complex structure of chemical bonds, a substance with a large number of polyatomic elements will also be required. Adhesive for polyethylene and polypropylene is made on the basis of methyl methacrylate. This is an ester compound of methacrylic acid, which in its pure form cannot exist under normal conditions, since it has negative temperature melting. To obtain an adhesive, xylene, complex organic and inorganic acids, chromic anhydride and other additives.

If you need to combine it with polyethylene, the easiest way is to use heat treatment. This method is very reliable, as it allows you to create a continuous, unbreakable seam that can no longer be broken without rough intervention. But such processing will also lead to deformation of the edges of the processed products, which is not acceptable in every case. Therefore, special glue is in great demand for modern market. Many different types of materials are made from composite materials decorative elements, which must be secured without compromising their integrity.

The mixture for combining polymers is sold in the form of a fairly thick paste. The kit also includes a special substance, the so-called activator. When it is added to the composition, the glue very quickly acquires the desired consistency and becomes ready for use. After diluting the mixture, there is no need to waste time, since the viability period is very short. On the one hand, this allows the products to quickly stick together, but on the other hand, it requires maximum efficiency and coordination from the worker.

The procedure for gluing elements

Working with glue is very simple; it does not require deep knowledge in the construction industry and many years of experience. Even beginners can handle all the technological procedures. To connect polymers or glue them to another surface, it is necessary to carry out the following sequence of operations:

  1. Clean and degrease surfaces. Many manufacturers claim that their products can be used on untreated surfaces, but this should not be trusted. In any case, the preparation will only take a few minutes, but a positive result of the operation will be guaranteed after that.
  2. Next, glue can be applied to the treated materials to bond polyethylene. It will harden in only 2-3 minutes, so immediately after application you need to fix the elements to be connected in the desired position.
  3. After completing the previous operation, you need to leave the treated products at rest for at least several hours. This time is enough for the glue to completely harden and adhere to the parts.

As you can see, the procedure is not much different from working with standard office glue. The only thing that needs to be noted is that all work must be carried out wearing protective gloves. Some elements included in the adhesive may cause irritation and allergic reactions to open areas skin. In case of contact with eyes, rinse them immediately with plenty of running water and consult a doctor.

Also, do not allow the substance to get into food products. It must be stored at room temperature out of the reach of children and pets. It will be much more convenient to work with glue if you purchase a special gun for this. It is charged with ready-made cartridges and allows you to evenly distribute the substance over the surface and strictly adhere to the required dosage. But it’s worth buying such a unit only if a large amount of work is planned. For local repairs, its purchase will be absolutely inappropriate from an economic point of view.

  • - temperature resistance - up to +80 degrees Celsius;
  • - service life is several years under normal operating conditions.

The substance has the best properties at an ambient temperature of +35 degrees Celsius. It is not afraid of humidity and direct exposure to water, is easily flammable and burns quickly when exposed to high temperatures. The shelf life after opening the package is no more than six months. When storing, you should take into account the fire hazard and do not keep the glue near open flame sources.

It is necessary to purchase the material in a specialized store to avoid getting caught in a possible counterfeit.

Polyethylene has long been popular in household material, unpretentious and inexpensive. Many people are faced with the need to glue polyethylene, for example, when arranging a greenhouse. It is worth noting that this material difficult to bond, but, nevertheless, this can be done using special adhesives.

So, to the question, what kind of glue will firmly glue polyethylene, experts answer - these are BF-2 and BF-4 adhesives, as well as glacial acetic acid, xylene and trichlorethylene. You can purchase these compounds in specialized stores.

What glue to use to glue polyethylene

What glue to use for gluing polyethylene - composition

The easiest way is to purchase structural adhesive in the store, which contains methyl acrylate. Its properties ensure rapid softening of polyethylene and its further gluing. The glue also contains inorganic and organic acids and xylene, chromic anhydride and various additives.

The advantage of using the mixture is that no additional processing of the material is required. However, polyethylene glue is quite toxic, so it is recommended to carry out work outdoors. The glue acquires its best properties at a temperature of +35C; it is not afraid of moisture, but is flammable. It is better to buy it in specialized stores so as not to run into a fake.

If there is a need to combine polyethylene with polyethylene, it is more convenient and easier to resort to heat treatment.

This technique allows you to obtain a strong, unbreakable seam. Among the disadvantages of the method, it is worth noting the deformation of the edges of the product.

Mixtures for combining polymers are available for sale, with a consistency similar to a thick paste. An activator is included in the kit. After adding it to polyethylene glue, it acquires the required consistency and can be used for the near future.

Gluing polyethylene - step-by-step instructions

To glue polyethylene, you do not need special knowledge and skills. Even beginners can cope with the task at home.

The operating procedure is as follows:

  1. Clean the surface and degrease it. Some manufacturers claim that this step is not mandatory, but experts still recommend spending a few minutes and under no circumstances skipping it.
  2. Apply glue to the treated material. It will only take a few minutes for it to harden, so the parts need to be attached to each other without delay.
  3. Leave the glued polyethylene elements for several hours until the glue completely sets.

In general, this algorithm is similar to working with any glue. True, you should take care about using protective gloves, since the glue can cause allergic reactions and is quite toxic.

It is more convenient to apply the adhesive using a glue gun, which can be loaded with ready-made cartridges. The mixture of them is distributed evenly, so it is easy to achieve the desired dosage. If you are planning a large amount of work, this device is worth investing in.

How to glue foamed polyethylene

Foamed polyethylene has a porous structure, therefore it provides high-quality warmth, steam and waterproofing.

Due to its low price, ease of operation and installation, it is actively used in construction. The most popular brands are Izolon, Vilaterm, Energoflex, Polyfom, Temaflex.

If the need arises glue foam insulation, experts recommend two-component adhesives based on methyl acrylate. Such compositions are characterized by high adhesion and are suitable for working with polyvinyl chloride, polyethylene, and polypropylene. An example is the well-known adhesive composition “Easy-Mix PE-PP” from WEICON.

Typically, in order to achieve high results in gluing polyethylene foam, the following procedures are additionally required:

  • surface treatment by sandblasting or grinding,
  • physical treatment, for example, thermal fire,
  • chemical treatment (usually the fluoridation method is used).

But when using “Easy-Mix PE-PP” you can do without additional preparation and treatment of surfaces due to the “primer” included in the composition, which changes the structure of the materials being glued, after which they easily adhere.

The use of “Easy-Mix PE-PP” adhesive for working with polyethylene foam both on a production scale and at home allows you to reliably and quickly fasten materials, while it is ready for use immediately after opening the package, it is easy to dose and mix, and apply.

The glue has a soft paste-like consistency, is not afraid of conditional “aging” and retains its properties for a long time even in open areas.

Currently, polyethylene film is actively used in everyday life, in some cases it is simply irreplaceable. Polyethylene is an unpretentious material, and it is also affordable. But all the people who use it sooner or later ask themselves the question: how can polyethylene be glued together? Simple glue cannot cope with this task; you will need a special glue for polyethylene with good adhesive characteristics.

Polyethylene is a very popular material, which is endowed with many useful properties. It is used as insulation, electrical insulator, packaging and greenhouse material, and reliable protection against moisture. Polyethylene is capable of absorbing neutrons, which are the most dangerous type of radiation. Due to the fact that this substance is a chemically resistant material, a reasonable question arises - how to glue polyethylene?

Bonding polyethylene surfaces is a process that has not only a chemical basis, but also an electrical one. This means that the glue must stick well to plastic film, and when hardening, firmly adhere the parts to each other. Modern industrial production has found ways to firmly glue polyethylene.

Here is an example of the most popular options:

  • welding of polyethylene parts with a hot object;
  • usage various types glue.

Hot iron for gluing polyethylene

Before gluing the polyethylene, using a hot iron, lay the edges of the plastic film on the surface wooden slats and align them. Fold the newspaper in two layers and iron the parts to be glued through it. The lath is necessary to create an even joint.

When using an iron, a reasonable question may arise: to what temperature should it be heated? It’s difficult to give any advice here, because it directly depends on how thick the plastic film you use. Therefore, adjust the temperature during the gluing process of the material. If the polyethylene parts become less durable and the seam is almost invisible, then the temperature must be reduced. If the parts are poorly connected to each other and no changes occur to them, then the temperature is too low and should be increased.

From the video you will learn a lot of new things:

To prevent burning of the polyethylene, the iron and the parts to be glued should not touch for more than one second.

To check the strength of the connection, pull the glued parts in opposite sides. If the seam comes apart, the process will have to be repeated again.

Bonding polyethylene with glue BF - 2 and BF - 4

To reliably glue the polyethylene film, you can use BF - 2 or BF - 4 glue. However, their use is possible only after the surface preparation stage. This work can be done even by people who do not have experience or practical skills.

  • before gluing the plastic film, clean and then degrease its surface;
  • Apply a layer of glue to the treated surface. It hardens very quickly, so apply the parts to each other immediately;
  • leave the glued parts for several hours until the glue has completely set;

This procedure is suitable for working with different types glue.

Remember that glue is a rather toxic substance that causes an allergic reaction. Therefore, prepare protective gloves for working with it in advance.

For greater convenience, apply glue glue gun, for charging which ready-made cartridges are used. This is especially true when gluing polyethylene in large volumes. For example, if you need to do work such as gluing film for a greenhouse.

Two-component acrylate adhesive for gluing polyethylene

An excellent option for gluing polyethylene is Easy – MixPE–PP adhesive, manufactured by Weicon. It is designed specifically for materials with low adhesion properties. As a rule, most liquids do not adhere well to plastic film. However, this adhesive contains tiny glass beads, which allows the adhesive to remain in place, creating a gap of the desired size. This ensures strong bonding of the bonded surfaces. It is one of the best adhesives for polyethylene, making it ideal for firmly bonding polyethylene greenhouse film.

The glue is a paste-like substance that is well dosed, easily mixed and applied to the surfaces to be glued.

Easy – MixPE–PP is good because it can be used immediately after opening. The adhesive contains a special primer that changes the structure of the surfaces intended for gluing. This makes it possible to ensure strong adhesion of materials at home, while preparatory work are not required for their processing.

Epoxy adhesive for polyethylene surfaces

Another means that can be used to glue polyethylene film is epoxy glue. It is worth noting that it is not designed specifically for polyethylene, but it does contain a phenol-formaldehyde resin that has excellent adhesion to polyethylene surfaces.

When using epoxy glue, the following sequence of work must be followed:

  • treat each of the bonded surfaces with emery cloth, degrease them and dry them;
  • Next, both surfaces will need to be treated with an oxidizing agent. To do this, you can use chromic anhydride (15 - 25% solution) or potassium dichromate (20 - 30% solution). Be extremely careful as these substances are carcinogens and are dangerous. An equally effective, but safer oxidizing agent is a strong solution of potassium permanganate. After treating the surfaces, you need to let them dry again;
  • prepare epoxy glue as stated in the instructions;
  • apply thin layer glue onto the surfaces to be glued and join them;
  • leave for several hours, observing temperature regime ranging from +30º to + 45˚Celsius. For stronger bonding, the holding time can be extended to a day.
