Two component (also referred to as 2K) polyurethane enamels are paints that require the intermixing of resin with a hardener. This causes a reaction that chemically bonds the two components together to produce a paint film that is generally  superior to one component paints in several ways:

1. Chemical resistance
2. Fade resistance
3. Abrasion resistance

While not all two component polyurethanes are equal in composition and performance, as a class, they are considered the gold standard for liquid coatings. Their excellent appearance and durability make them a popular finishing choice for a wide range of products and substrates.
