In the automotive industry, a 2K paint thinner is a specialized solvent used with 2K paint systems to achieve a professional-grade, high-durability finish. The term "2K" refers to the two main parts that are mixed just before use: a base paint and a separate hardener (or activator). The thinner, sometimes called a "reducer," is the third component added to this mix.
The primary function of a 2K thinner is to lower the paint's viscosity, making it easier to apply with a spray gun. This is critical for achieving a smooth, uniform, and high-quality finish without defects such as "orange peel," runs, or sags. This 2K paint thinner can also be used to thin polyurethane paints.
There are different variants of 2K thinners in our product line, varying in quality and drying time.
