Composition and scope of application of paint with liquid plastic, top 11 brands

Liquid plastic for windows refers to compositions created on the basis of polymers and having a fluid consistency until contact with air (in a certain temperature range) or chemicals. The material is used in the installation and repair of translucent structures for sealing seams, eliminating voids and connecting individual elements. It is resistant to precipitation, temperature fluctuations, and does not fade in the sun. Liquid plastic for PVC windows is called an improved sealant, since it perfectly copes with the functions of standard analogues, but is free from most of their disadvantages: changes in color and shape, peeling from the surface, etc.

Composition and features of liquid plastic

The name “liquid plastic” combines finishing materials with various purposes: paint, enamel, coating for cars, glue and polyurethane for molding. They differ in composition and properties:

Thanks to the plastic-effect body coating, the car looks clean and shiny, just like after a wash. Dye is added to the anti-corrosion composition to correct the color of the car. An analogue of liquid plastic is polycarbonate glass, which is used to build greenhouses, and fiberglass for bottles.

What kind of material is this

Adhesive for plastic windows is based on cyanoacrylate.
Other esters and polymer compounds that provide high adhesive ability can be used as the main component: polyurethane, high-viscosity organic or synthetic resins (alkyd, acrylic). The finished product has low fluidity, but quickly fuses with the material, acting on the principle of diffuse welding. Polymer plastic is suitable for small home repairs and is used to seal leaks and ensure the integrity of water pipes. Due to its good adhesion, liquid plastic connects surfaces of various natures; they do not require thorough cleaning before processing.

Compound

Liquid plastic for windows is produced in two forms: single-component and multi-component. In a one-component composition, the main ingredient is a solvent, which dissolves part of the plane being joined, allowing macromolecules to penetrate inside, forming a durable seam. Other additives are amorphous viscous substances. Plasticizers are added that increase heat resistance, moisture resistance, reduce fading, and are fungicidal. Natural and artificial pigments and modifiers are added.

Multicomponent adhesive materials are created from a complex of compounds. Two-component products require pre-mixing in strict proportions before application. They are often used in the creative field for pouring plastic figures and in design for making parts. They are characterized by rapid hardening and long-term retention of shape.

Purpose

The adhesive product is effective in any repair work. It efficiently glues objects from a variety of materials:

• organic glass;
• wood;
• plastic;
• polycarbonates;
• plastic and aluminum windows with rigid PVC profile;
• polyvinyl chloride;
• polyethylene terephthalate glycol (PETG);
• metal with modular coating;
• sheet polystyrene.

Due to the wide range of receptive surfaces, polymer adhesive is versatile. It is used both for repairs and for creativity. Liquefied plastic, when hardened, holds its shape for a long time, therefore it is applicable in the process of making crafts.

As a sealant, liquid plastic shows consistent results. By caulking the hole in the drain pipe, a sealed condition is created and the hole no longer leaks. However, experts recommend not using the product in places of direct and constant contact with water, because... this negatively affects the grip strength.

Areas of application of plastic paint

Paint with liquid plastic is suitable for wood, drywall, brick, concrete. Using plastic paint, walls and ceilings are prepared for wallpaper and final painting. Liquid polymer is used in the following areas:

• construction;
• Finishing work;
• Automotive industry;
• shipbuilding.

Polymer paint is used to apply car markings on city streets and highways. Liquid plastic is used to paint water and gas pipes, fences, gates, and metal safes. Enamel with polyurethane, acrylic and alkyd protects surfaces from precipitation and ultraviolet radiation. It is also used to cover wooden architectural decorations and balconies.

The use of liquid polymers in various activities

Flowable polyvinyl chloride compounds are used to seal polymer windows. Polyvinyl chloride, when introduced into window cracks, promotes rapid chemical welding with the plastic structure, resulting in a transparent, homogeneous structure.

Terms of use

They work with liquid plastic at a temperature of +5…+35 degrees. After application, the paint sets within an hour. For outdoor work, choose a dry, windless day. If the temperature indoors or outdoors is above thirty-five degrees, it is better to postpone painting. In the heat, the paint peels off. Do not work with liquid plastic during sudden temperature fluctuations and high humidity. Condensation will reduce the strength of the coating. The composition is applied with a roller, paint brush or spray gun.

Secrets of coloring silicone products

If problems with painting rarely arise with the previous type of polymer, then with liquid and paste silicone things are completely different. In truth, experts call it one of the most difficult tinting compounds. Why? The reason is the special structure of silicone, in which there is no room for foreign impurities - pigments. As a result, even with proper surface preparation and compliance with all painting rules, the risk of paint peeling remains high. So, let's get acquainted with some secrets of coloring silicone products.

• Do not attempt to paint silicone products with traditional coatings. Adhesion is only possible with silicone-based paints. The most suitable option is special metallic pastes with additives.
• Do not forget that the softer the silicone product, the worse the paint will adhere to it. This is due to the high content of inert oil in soft silicone, which does not allow coatings to linger on the surface.
• You can paint both the silicone mass during its preparation and the surface of the finished products. Another method of painting is subsurface. Craftsmen recommend using it, since the risk of peeling is minimal.

Unlike paints, all kinds of decor “get along” perfectly with silicone. To decorate products you can use glitter, flock and pearlescent powders. It is strictly forbidden to paint or decorate baking dishes and other food products!

Aerosol paints

This category of coatings includes paints already known to us, namely, polyurethane enamel and soft-touch. But you don’t need brushes to apply them. In addition, the coatings in the cylinders are completely ready for use. Unlike previous materials, they do not need to be mixed, which greatly simplifies the work. Painting products with spray paints is an art that can only be perfected over time.

The main “enemy” of a master working with a cylinder is unsightly smudges. They occur if you stay in one place for too long while painting.

There is no need to achieve a perfect surface while applying the first layer. In any case, repainting will be required, so for the first time it is better to focus on the absence of smudges, rather than on eliminating gaps.

The second layer can be applied only 30-40 minutes after the first. After completing the work, inspect the surface. If you are satisfied with the result, leave the product for 2-3 days for the paint to completely polymerize. If not, apply another layer of paint 30 minutes after the second.

The choice of shades of aerosol paints will pleasantly surprise the most demanding craftsmen. Manufacturers produce coatings that not only color plastic, but also make it resemble wood, metal, etc.

Pros and cons of use

Liquid plastic for windows has many advantages. It is easy to use, adheres quickly and firmly, does not emit toxic products, and is environmentally friendly. Its versatility allows the product to be used in many areas to satisfy creative needs. Once cured, a strong, sealed seam bond is formed. Due to the variety of brands on the market, the user selects the specific option he needs.

Among the shortcomings of the product is the strong odor of the original liquid, which complicates operations. Drying too quickly limits the technician’s time to align the adhesive line. For many people, the high price is a barrier to purchase.

User reviews

Evgeniy G.

I bought liquid plastic for windows and was pleased. Fixed the crack without fuss, no long preparations, degreased and applied! It holds tightly and is almost invisible. The price confused me at first, but it took very little mixture, so it will last a long time.

Andrey S.

I always keep a tube of PVC glue at home in stock. Convenient to fill any hole. I recently used it to seal a hole in a pipe. The composition is transparent, has a strong smell, but the patch is odorless. It sets instantly.

Anastasia M.

I buy compound to make decorative figures. I really like that once it hardens, the design is strong enough to sharpen and touch up here and there. The paint goes on great! The product does not smell of anything.

Description and technical specifications

Liquid plastic is a one-component transparent polymer with low viscosity. It has the properties of diffuse welding, almost instantly connects elements, creating a strong monolithic seam, almost invisible during external inspection. The frozen mass has the following characteristics:

• resistance to temperature changes;
• low heat conductivity;
• resistance to aggressive environmental influences;
• UV resistance;
• high strength;
• environmental friendliness;
• safety;
• long-term color retention.

In terms of composition, it is liquid plastic, which, penetrating into the structure of the parts being connected, after polymerization forms a monolithic connection with an even, dense structure.

After application, the mixture sets in 2-4 minutes, and complete hardening, providing maximum strength, occurs within a day.

How to apply it correctly?

To apply liquid plastic, you should contact a professional installation organization. If this is not possible, this work can be done with your own hands , provided that the following flow chart is strictly followed:

• 
  The surface to be processed must be cleaned of dust, grease and other sources of contamination.

• Before applying the substance, it is necessary to inspect the surface for the absence of cleaning agent residues or lint from rags or paper towels.
• Experts recommend cleaning the surface with acetone-containing substances, which quickly evaporate into the atmosphere and do not contain greasy impurities.
• After cleaning, the surface is dried with a hair dryer until traces of moisture are completely removed.
• The tube with glue is opened, if necessary, the seal is pierced with the spike of the lid, and, in the case of using a container with a plastic cap, its tip is carefully cut off with scissors.
• The tube with the dispenser is brought to the assembly seam or crack, after which the master begins to slowly squeeze the composition out of the container.
• 1 minute after application, the substance begins to polymerize and can be smoothed out with slight pressure using a plastic scraper or fingertip. Before carrying out this procedure, it is recommended to moisten the contact surface in water to prevent sticking to the adhesive composition that has not completely dried.

Before starting to use a plastic window, you should wait at least a day, since this is the period required for the final formation of the crystal lattice.

Errors and difficulties during work

When applying glue and surface treatment, the master can make a number of mistakes that will affect the result :

• If dust particles remain on the surface, the glue begins to peel off after drying.
• When applying the composition to a wet surface, the substance loses all adhesive properties.
• In case of uneven extrusion or delay in the movement of the tube, the processing line will be uneven, which will require additional processing of the material.
• When working with glue in subzero temperatures, the substance may lose its performance properties.
• If the adhesive is not pressed after application, air particles may form between the contact surface and the substance, which affects the strength and uniformity of the material after polymerization.

Considering that the liquid composition contains toxic volatile substances, you should follow safety precautions when working - use gloves and a respirator.

Application process of this sealant and precautions

As a rule, the process itself does not look complicated and is easy to do:

It is important to first clean the surfaces of parts to be glued from dust, dirt and grease, and then dry them thoroughly. To perform this procedure, it is permissible to use only napkins or small pieces of fabric that do not have fine lint. It is important to leave an even strip along the length of the entire joint, onto which the liquid plastic itself is then applied.

It is important to do this very carefully, never smearing the sealant from the surface of the part. After application, you must wait about a quarter of an hour. Within the recommended period of time, the sealant reaches complete drying. In cases where liquid plastic accidentally gets on the surface of metal elements or parts, it is necessary to use heavy artillery in the form of appropriate cleaners.

As you can see from the material described above, this procedure is extremely simple and even a beginner can perform it.

Attention! When working with this material, you must remember that it contains cyanoacrylate, which is a dangerous chemical.

When working with it, it is important to follow the safety rules:

• Keep the product away from people prone to allergic reactions;
• Work with it only with strong gloves;
• Put a protective mask on your face;
• After finishing work with it, ventilate the room well.
