What is the Difference Between 1K and 2K Automotive Paint?
1 Answers
1K and 2K automotive paints differ as follows: 1. 1K: 1K refers to single-component color bases that rely on solvent evaporation to cure and form a film. In automotive repair paint series, there are 1K solid color bases, 1K pearl/metallic bases, and 1K primer surfacers (such as Su Grey). These require good coating adhesion, weather resistance, smoothness, uniform and clear metallic or pearl arrangement, and excellent gloss and line reflection when coated with matching clear paint. 2. 2K Color Bases: 2K refers to two-component color bases, consisting of Part A (hardener) and Part B (resin), which must be mixed in a specific ratio to undergo a chemical reaction for curing, film formation, and drying. In automotive repair paint series, there are 2K solid color bases, 2K clear coats, and 2K epoxy primers. These require good fullness and gloss, firm paint film, and excellent weather resistance.
