What kind of material is this for plastic structures??

A special polymer mixture known as liquid plastic adhesive is intended to seal joints between a translucent structure’s PVC frame and an opening in an outer wall.

Considering the substance enables you to accomplish the following outcomes:

• Used as diffusion cold welding for joining plastic parts.
• After application and polymerization, it forms a smooth, uniform surface that does not stand out from the general PVC construction material.
• The chemical composition includes the same components as a standard plastic window profile.

Liquid plastic is a one-component material that is sold in transparent or white forms. It polymerizes when it comes into contact with air.

Composition

The following fundamental ingredients are used in the synthesis of liquid plastic, a complex polymer compound:

• Polyvinyl chloride compound, identical in composition to standard plastic.
• Cyanacrylate is a substance that gives structure and strength to the product after hardening.
• Thermoplastic polymer, designed to store the substance in a viscous form.
• Hardener, which reacts with atmospheric air molecules for rapid polymerization.

"Liquid plastic" glue comes in professional and home varieties. Installation teams are provided with two-component compositions that include hardeners. The degree and rate of polymerization of the liquid substance after application can be independently controlled by the master, contingent upon the adhesive composition’s concentration.

Purpose

The following kinds of construction, installation, and repair work are completed with liquid plastic:

• When fixing auxiliary elements of PVC framing frames for translucent structures – window sills, slopes and other framing elements.
• For sealing seams between homogeneous plastic elements when joining them in a plane or in an orthogonal direction.
• If necessary, install decorative elements for framing the window structure on both the front and interior sides.

Standard silicone or acrylic sealants, which shield installation gaps from moisture, dust, and solid pollutants from the atmosphere, are frequently replaced with liquid plastic.

Specifications

All forms of liquid plastic share the following technical traits, regardless of the producer, pricing strategy, amount of glue used, and other factors:

• The volumetric mass of the substance ranges from 990 to 1100 kg/m3 .
• Depending on the chemical composition, it can be supplied in liquid or viscous form, which determines the ease of application and the degree of penetration of the substance into hard-to-reach places.
• It is characterized by an increased rate of polymerization – it begins to hold its shape without the possibility of adjustment within 2 – 6 minutes after application.
• Strength gain after application lasts no more than a day until the composition is uniform with the main plastic element.
• When using liquid plastic, special attention should be paid to the ambient temperature. Optimal parameters are from 20 to 25 o C. At temperatures below 5 o C, it loses its physical and mechanical properties, the hardening of the substance practically stops completely.
• When working with liquid plastic, care must be taken to ensure there is no excess humidity in the room. The maximum permissible concentration of water vapor should not exceed 55 – 60%.

The material shouldn’t change color once it has dried. If the clear composition starts to get hazy, either there is excessive humidity present or there was inadequate surface preparation.

Composition requirements

A number of operational and technological requirements are imposed when using a substance:

• High level of adhesion to plastic and other building materials.
• Increased resistance to temperature changes, regardless of where the substance is used.
• Mechanical strength of the material.
• No shrinkage with subsequent crack formation.
• Absolutely waterproof.
• Resistance against exposure to weakly concentrated alkaline and acidic reagents.
• Increased rate of polymerization and development of design strength.

Every adhesive composition is made at the plant in compliance with pre-established specifications that are released following extensive testing of the substance. The manufacturer gives the customer a product passport with all the maximum operating parameters when they buy a large batch. Liquid plastic retains its manufacturer-declared properties once these indicators are met.

For effective PVC window installation and repair, liquid plastic glue (like Cosmofen and Creative) is required. Strong, long-lasting bonds are created by these adhesives, guaranteeing that windows are weather- and weatherproof. This post will go over the qualities and advantages of these adhesives, as well as practical application tips and reasons why pros use them for both new installations and repairs. In any building or remodeling project, knowing how to use liquid plastic glue correctly can significantly extend the life and functionality of PVC windows.

Famous brands

Even though liquid plastic is still relatively new to the consumer market, it is already being produced by a number of well-known companies that specialize in sealant production.

Because of the competition this fosters among factories, quality and a reasonable retail price are guaranteed. The following companies are among the most well-known producers of "liquid plastic" glue:

Cosmofen

• does not crack in winter;
• does not support the development of bacteria.

Retail pricing for a 300 ml plastic container and a 100 ml hardener in a separate container begins at 700 rubles.

Poly Art Fast

Two-part mixture from a chemical plant in Russia. One of the adhesive categories under consideration with the fastest setting speed. Its beige color makes it easy to use for installing window structures that are ivory or cream in tone.

A substance weighing 640 g in total can be purchased for 990 rubles per unit. You must ensure that the product you select is authentic, as fake goods do not offer the right amount of strength and adhesion. You should read online reviews from actual customers before making a purchase of liquid plastic.

Criterias of choice

Selecting the appropriate liquid plastic for window structure installation or repair is crucial to achieving the intended outcome. Regardless of the composition’s technical attributes and component count, the following considerations need to be made:

• The optimal level of viscosity. The substance should not spread along the processed plane, but at the same time, too thick the composition will not be able to penetrate inaccessible places.
• After polymerization and complete solidification, the glue should keep in shape, not crack and have increased resistance against shock effects.
• High -quality liquid plastic can be stained in any color using acrylic compositions.
• After drying, glue can be sanded with abrasive materials without loss of the structure of the crystal lattice.
• The deadline for polymerization of the quality composition should not exceed 10 minutes.
• After drying, liquid plastic should have a neutral smell and not release toxic toxins into the atmosphere when heated.

You should familiarize yourself on the manufacturer’s website with the details of manufacturing the product before making a purchase of liquid plastic. Usually, a copy of the environmental safety certificate—which certifies that the composition is safe for use in residential settings—is also attached.

How to apply correctly?

In order to apply liquid plastic, you ought to get in touch with a reputable installation company. If this isn’t feasible, you can complete the task yourself as long as you strictly adhere to the following technological map:

• The surface to be processed must be free 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 that quickly evaporate into the atmosphere and do not contain greasy impurities.
• After cleaning, the surface is dried with a hair dryer until all traces of moisture are 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.
• A tube with a dispenser is brought to the mounting seam or crack, after which the master begins slow squeezing out the composition from the container.
• 1 minute after application, the substance begins to be polymerized, and it can be smoothed out with a slight pressure with a plastic scrap or finger pad. Before carrying out this procedure, it is recommended to moisten the contact surface in the water to exclude adhesion to not completely dry adhesion.

You should wait for at least a day before operating a plastic window, as this time is necessary for the crystal lattice to fully form.

Errors and difficulties during work

The following mistakes that the master can make when applying glue and surface treatment could have an impact on the outcome:

• If particles of dust remain on the surface, the glue begins to exfoliate 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 at 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.

Wearing gloves and a respirator while working is advised because the liquid composition contains volatile and toxic substances.

Pros and cons of use

Professionals and amateurs alike frequently use liquid plastic adhesive because of its flawless qualities and enhanced dependability. Benefits of using glue:

• After hardening, the substance forms a structure identical to a standard PVC product. Thus, a monolithic, inextricable structure is achieved.
• The adhesive properties of the material allow it to be used for cold welding of any polymer materials, regardless of the nature of the damage and the length of the installation gap.
• Convenient for joining mutually orthogonal slopes or for sealing a plastic window sill board with a window frame.
• The substance does not support the proliferation of microorganisms. Mold does not form on the surface, regardless of air humidity.
• Adhesion does not occur through simple adhesion of particles, but at the molecular level, that is, the principle of material diffusion is applied.
• After polymerization, the connected surfaces are absolutely sealed and do not allow moisture, grease and dust particles to pass through.
• Almost every composition has a fire safety certificate, which indicates an increased combustion threshold in the event of a fire in the room.
• When placing liquid plastic on an untreated surface, not only better adhesion of materials is achieved, but also the smoothing out of minor defects.

Notwithstanding its many benefits, the substance has a few minor drawbacks as well:

• Increased retail price. Using standard silicone, acrylic or rubber sealants is much cheaper.
• Difficulty in correcting errors due to rapid strength gain.
• Rapid polymerization of the composition complicates the process of finishing the joint surface.

No matter the operating conditions or the temperature and humidity parameters of the air indoors or outdoors, high-quality adhesive compositions can function for up to 15 to 20 years without breaking down or needing to be replaced.

User reviews

When sealing PVC elements for transparent structures, many customers who have used liquid plastic glue share their experiences with other network users, pointing out both benefits and drawbacks.

• No odor, quick application, high mechanical strength.
• Hardening of the material too quickly after application.
• The application of the material requires experience and skill to achieve a flawless result.
