Two-component paints are paintwork materials( paintwork materials), the components of which are supplied separately for further mixing before use. In comparison with one-component, two-component paints are characterized by increased quality: usually one layer is enough to create a high-quality coating.

formulations Composition types
Most often two-component compositions are produced on the basis of acrylic, polyurethane, epoxy resin. Also thixotropic and urethane-alkyd paints are produced. Differences between species concern not only the chemical composition and mixing proportions, but also the consumer characteristics, and hence the scope.
Areas of application:
- road transport;
- industrial mechanisms( prevent external negative effects on the treated surfaces);
- aluminum and its alloys( increase the adhesive qualities of materials);
- surfaces, galvanized( for example, galvanized steel);
- synthetic materials( polyesters, composites, etc.).
Most often, acrylic paints paint metal products, because such paints are distinguished by reliability, durability, bright tonality, resistance to ultraviolet radiation( which is especially valuable for surfaces located in the open air).
Two-component paints based on epoxy resin - the preferred option if you need to get a strong coating, resistant to chemical attack( including resisting acids and alkalis).Such formulations are resistant to complex climatic conditions( high and low temperatures, abundant precipitation).
Epoxy varnishes are used for painting tanks with chemical compounds. Paintwork material is perfect for painting surfaces and metal and concrete.
It is convenient to use such a paint from a technological point of view, since epoxy compounds are universal and they can process all surfaces of the room.
Two-component paint based on polyurethane is the best solution for painting wood surfaces. Polyurethane is also suitable for other materials, especially metallic materials such as steel, cast iron, aluminum, etc.
Advantages of polyurethane two-component paints:
- are easily mixed with other components;
- high hiding power and for a high-quality coating, one layer is usually enough;
- are characterized by stability, as a result of which no staining occurs after staining;
- are resistant to mechanical influences( bumps, scratches, etc.);
- surface is aesthetically pleasing( brightness, gloss, etc.).
Other variants of
formulations Another version of the two-component paint is thixotropic solutions. They are widely used for painting wood products, including in the furniture industry. The paint is usually based on an alkydoamine composite material, due to which the surface is transferred to higher strength and high resistance to external influences.
For surfaces subject to increased friction and wear, urethane-alkyd paint is used. Such paints, in particular, are used for painting concrete and wood structures.
Please note! Two-component compositions are much larger than listed in the article, but here we are talking about the most proven time.
Judging of new paint and varnish materials is sometimes quite difficult due to the lack of a long practice of their application. Two-component paints are not in vain used at industrial facilities. This fact indicates their reliability, safety and durability. However, the cost of such paints is high, so their use is justified on vast surfaces. Small parts can be painted with ordinary paint, for example, from an aerosol can.
