Liquid plastic (two-component) is a polyurethane system that can harden very quickly. From polyurethane liquid plastic, using the method of open casting (rotation), you can produce souvenirs, create furniture decor and structural elements. Products made from liquid plastic last much longer than their counterparts made from any other materials.
The polyurethane system has a high degree of detail and is suitable for casting small parts and small decorative items.
In the Polimerika online store you can always buy liquid plastic at low prices.
Removing plastic paint
- Random drops of glue on the surface of the plastic structure are removed with a thin blade. The next step is to treat the area with a special solvent.
- Water-based plastic paint is removed from the surface with water before it dries. When the material has already dried, it is removed with a knife.
- The metal-based Cosmofen material is removed with a solvent. When it dries, it can be easily removed. The coating looks like a film. The tenacity of the composition with metal is zero.
Areas of application
Modern manufacturers have come up with many different products for processing and insulating windows. ZhP is able to cope with the cracks that form during the installation of slopes. Installing such elements allows you to cope with several construction defects:
- It is the slopes that allow you to transform the window structure, due to which it will acquire an improved and harmonious appearance.
- During dismantling of old panels, deformation of the opening may occur. It can be easily removed using slopes.
- The level of lighting in the room is significantly improved. The desired effect is achieved due to the fact that the opening is equipped with an additional reflective surface.
- High-quality slopes allow you to increase the level of thermal insulation, due to which you can ensure the most favorable microclimate in the room.
- The penetration of dust and extraneous noise is prevented.
All these factors influence the fact that a window structure cannot do without installing plastic slopes of suitable size. But in order for such products to fully cope with the obligations assigned to them, their connection with the main fabric must be as strong as possible. To solve this problem, the ZhP was developed. The craftsman must carefully close the technological seams, as well as fix some auxiliary elements (plates, drains, protective strips). This is precisely what explains the need to use universal sealants.
Specifications
The product allows you to quickly combine elements to form an imperceptible, even seam. The beneficial properties of PVC glue are due to a set of characteristics:
- non-toxic gluing;
- resistance to high temperatures and temperature changes;
- water resistance;
- not exposed to sunlight, protected from UV radiation;
- setting in a short time (2-4 minutes);
- increased degree of resistance under the influence of aggressive environmental factors;
- does not change color over time;
- easy to apply.
How to work with polyurethane liquid plastic
To obtain liquid plastic for molds, you need to mix the two components included in the package in a 1:1 ratio. The components contained in the package can only be mixed if the filling system has warmed up to room temperature.
Before starting work, you need to shake the two components (2-3 minutes of shaking will be enough). Stir until the mixture becomes homogeneous. Mix the two components only with a wooden stick. You can mix by hand, but you can also use a mixer (in this case, you should not mix the filling system for more than 25-30 seconds).
Pour the filling into the prepared special mold and wait 20 minutes. After the specified time has passed, it is necessary to remove the finished product from the mold. Important! The mixture, freshly prepared for use, should be used within 2 minutes. Otherwise, the fill may lose some of its properties.
Criterias of choice
When selecting PVC glue, you need to take into account the purpose of the purchase. In rooms with high humidity, compositions that are unstable to moisture should not be used. For outdoor installation, you should choose materials that can withstand changing weather conditions. If a product is needed for creativity, you should pay attention to safe and least toxic options without a strong odor.
Selection criteria:
- after drying, the seam should not smell;
- maximum polymerization time 10-15 minutes;
- the mixture is not too dense, but does not spread;
- possibility of processing with grinding tools;
- availability of certification;
- impact resistance.
Further surface treatment
You can remove Cosmofen residues from tools using a cleaner from the same manufacturer. If glue gets on the PVC base, wait until the drying time is complete and carefully cut off the excess with a thin blade.
Not completely dried glue can be wiped off with Cosmofen 597 or Cosmo CL-300.110 cleaner. But it is better to immediately carry out all the work carefully without any blots, because due to the high strength of the hardened composition, it is not always possible to remove its excess and stains.
Grouting of seams is started only after the composition has completely dried, so as not to break the tightness of the seams.
Composition requirements
Before releasing a product for sale, it is carefully checked to ensure compliance with technical requirements. The test is carried out by qualified employees of independent companies during practical tests. The results are entered into the product passport - the main document required for delivery to stores.
A quality product must be mechanically strong, resistant to acids and alkalis, and alcohol-containing solutions. The seam formed does not allow moisture to pass through, does not shrink after complete drying, does not crack or peel off.
The composition quickly hardens, polymerizes, and the lubricated area becomes stronger. It is not subject to temperature changes, pressure, or ultraviolet radiation. The adhesive product exhibits strong adhesion to a number of building materials.
Use of casting resin
The use of injection molded plastics is intended for the production of various products:
Casting method
- artistic products (masks, sculptures);
- nozzles, bushings;
- relief products;
- medical prostheses;
- building blocks;
- rollers, wheels;
- containers resistant to chemical reagents.
For casting, it is customary to use a component composition, which is based on 2 elements: a base and a hardener. Both components interact when mixed, resulting in a solid polymer structure.
A technology in which plastic is cast into a silicone mold is widely used. Take two mixtures, combine them with each other and mix thoroughly. The resulting two-component mixture is poured into a specially prepared silicone mold and left for 15 minutes. After hardening, the outer shell of the mold is carefully removed. The output is a solid product that exactly repeats the configuration of the original silicone mold.
There are many different types of molds for pouring various products
To create medical prosthetics, masks and sculptures from plastic, they use the technology of casting it into a polyurethane mold. Depending on the components used, the output is a material with the desired degree of transparency.
Precautionary measures
Since Cosmofen glue contains cyanoacrylate, which is not entirely safe for humans when exposed directly to the body, you should follow some rules so as not to harm yourself.
1. All work must be carried out with gloves so that the glue does not get on the skin, otherwise this can lead to instant gluing of hands to things or to each other.
2. To avoid inhaling glue vapors, you must wear protective equipment: a face mask or a respirator.
3. The room must be well ventilated.
4. For people with allergies, it is better to leave this work to someone else to avoid undesirable consequences of exposure to Cosmofen.
5. Sealants are quite flammable. Using open fire near glue or smoking indoors is strictly prohibited.

Flaws
- Quick adhesion to the surface is a minus for beginners. You need to work with the mixture quickly and correctly, since there is little time left to correct the position of the parts to be glued.
- The substrate to be treated must be completely dry. Only after complete polymerization can the seam be exposed to moisture.
- Some products are difficult to remove from the surface if accidentally applied. To remove excess you need a special solvent.
- Cosmofen is not good for gluing porous materials.
- Fixed, non-elastic seam.
- Cosmofen is highly flammable; fire safety regulations must be observed.
