FAQ

The main difference between single-component and two-component paint is in how it hardens and forms the protective film.

Single-component paint (1K) is ready to use: it does not require catalysts and dries by solvent evaporation or exposure to air. It is easier to apply, ideal for small touch-ups or DIY projects. However, it offers lower resistance to scratches, solvents, and UV rays compared to two-component versions.
Two-component paint (2K), on the other hand, contains a colored base to be mixed with a hardener (catalyst). The resulting chemical reaction creates a much more durable and glossy film, typical of professional coatings. This type of product is preferred in body shops, especially on new cars or complete restorations.

In summary: 1K for convenience and quick touch-ups; 2K for durability, gloss, and professional results.

Acrylic and polyurethane paints are among the most used in the automotive sector, but they have very different characteristics.

Acrylic paint is based on light resins that dry quickly. It is easy to apply, sands well, and provides a good aesthetic effect, but offers medium resistance to external agents. It is perfect for touch-ups, vintage restorations, or for those seeking a balance between quality and simplicity.
Polyurethane paint, on the other hand, is a high-performance two-component product: it resists impacts, scratches, solvents, and UV rays better. The result is a harder and glossier film, with long-lasting shine. However, it requires more care in mixing and proper protection during application, as it contains isocyanates.

In summary: acrylic for convenience and a “craft” finish, polyurethane for durability and a professional look.
