Lacques for polymer coating (plastic): types, features, pros and cons, classification and properties of popular varnishes

Polymer coatings, also referred to as plastics, are ubiquitous in everyday life and can be found in everything from car parts to household goods. Different kinds of lacquers are applied to these materials to improve their appearance and longevity. These specialist varnishes impart a desired finish—matte, metallic, or glossy—while also protecting the surface. Choosing the appropriate lacquer for a given application can be made easier by being aware of the types and characteristics of these lacquers.

For polymer coatings, a variety of lacquers are available, each with special characteristics. The most widely used types of lacquers are epoxy, polyurethane, and acrylic. Acrylic lacquers are renowned for being easy to apply and having a rapid drying time. Polyurethane lacquers are perfect for high-wear surfaces because they offer exceptional durability and chemical and scratch resistance. Superior adhesion and protection are provided by epoxy lacquers, particularly in abrasive environments.

Every lacquer type has advantages and disadvantages. Even though they are simple to use, acrylic lacquers might not be as durable as alternatives made of polyurethane or epoxy. Even though they are long-lasting, polyurethane lacquers can be harder to apply and take longer to cure. Although epoxy lacquers offer superior protection, they can be more costly and necessitate careful mixing and application methods.

Depending on their chemical makeup and intended application, these varnishes can have different properties and classifications. For instance, water-based acrylic lacquers are good for indoor use because they produce less volatile organic compounds (VOCs) and are environmentally friendly. Contrarily, solvent-based lacquers perform better in terms of finish and durability but can be more harmful to the environment and need to be applied with adequate ventilation.

Well-liked varnishes on the market meet a variety of requirements and tastes. While some are focused on offering long-lasting protection and a high-end finish, others are made to be simple to use and apply quickly. Making an informed decision can help ensure the best outcomes for any project involving polymer coatings. This can be achieved by being aware of the unique qualities and applications of these lacquers.

Why is plastic covered with varnish

The lacquered composition serves as a barrier. It enables you to preserve a polymer base and stop its deformation as a result. The potential to create a decorative surface is the second moment. On the plane, a thick film with a glossy shine develops.

Furniture varnish

You can alter the color scheme or deepen the base of the object by using specific solutions. Thus, by combining multiple tones, it is possible to create an optical illusion on the surface.

You can increase the operational qualities of polymer parts by varnishing them properly.

  • Thanks to a strong film, it is possible to prevent mechanical destruction of the plane.
  • Thus, the risks of chips, scratches and cracks are reduced. However, when choosing, it is necessary to take into account the composition of the varnish.
  • The fact is that not all solutions can be used for plastic elements.

Malar brushes

Certain types, for instance, spread out quickly on the aircraft, whereas others do not dry out after application. The third species starts to adhere to the surface and leave stains.

Which varnish to choose for plastic

It is advised to use common solutions made especially for plastic if the varnish is being used as an additional layer of protection. These compounds can produce a matte film or a glossy shine after application.

Amber oil varnish

Paints and varnishes have pigments in their composition that give the coating an extra color. Together, let’s determine which substances are appropriate for use in plastic processing.

It is advised that you familiarize yourself with the components that went into making the paintwork before purchasing it. Expert experts will assist in making the decision.

You can find out about the product’s features, precautions, and scope by reading the packaging instructions.

  • Liquids are not suitable for processing plastic, which contains alcohol, acetone and chemical solvents.
  • These components provoke the appearance of a chemical reaction between the liquid and polymer plastic.
  • For work, it is better to use brands with water -soluble components.
  • After application, they are evenly distributed on the surface, dry quickly and do not form caustic compounds.

Aerosol varnish for metal

For processing plastic, it is not advisable to use polyurethane or acrylic varnish based solely on water components without the addition of latex. As a matter of fact, divorces start to surface during the drying process. It eventually turns into the reason for chips and scratches.

Regarding uterine degree, the compositions are separated into:

  • Glossy;
  • Half -gloss;
  • Matte.

The varnish is craquelure

The use of a specialized protective filter to shield the finished coating from UV rays is regarded as one of the most crucial aspects of painting.

You can use this mixture for plastic processing if this component is present in the composition. When temperature and solar insolation change over time, this kind of coating won’t activate and won’t deform.

Alciden varnish

  • Polyurethane types of varnish after drying are accompanied by the appearance of a protective film.
  • It allows you to maintain the appearance of the product from scratches and possible deformations.
  • The painted plane is easily washed and cleaned using household chemicals.
  • The mechanical effect of abrasive particles does not change the quality of the protective film. The presence of glossy shine helps to achieve an impeccable look.

Water-based varnishes have a clear advantage when it comes to their environmental makeup. They don’t contain any aggressive ingredients and don’t damage the body. Such varnish does not develop a caustic odor when worked with.

How to choose a degree of dullness

Here, the choice of solution is based on personal preferences. Every variety has high aesthetic qualities as well as advantages. A glossy coating produces a brilliant, thick layer. Multiple applications of the composition allow for the creation of the "mirror" effect, which reflects light.

You can enhance the plastic’s color quality with matte film. The subject’s decorative qualities can be enhanced because of its homogeneous structure.

Glossy film is said by experts to be more practical. However, accuracy needs to be kept in mind while operating. The truth is that a single scratch can ruin the product’s appearance.


Paints and varnishes are applied almost exclusively by spraying. The paint is evenly distributed across the plastic’s surface thanks to this technique.

When handling aerosols, it’s important to consider the following requirements:

  • A spray can be kept perpendicular to the base of the object;
  • The distance between the aerosol and the surface should be at least 30 cm. If it is smaller, that stains can form on the plane;
  • Each layer should dry for 30-50 minutes. If you neglect this requirement, then during further operation the risks of the appearance of deformations and chips on the decorative plastic plastic increase are increased.
