The primary component of paint is referred to as the resin. The type of paint comes from the resin system – Polyvinylidene Fluoride (PVDF), Polyester, Acrylic, Polyurethane or Epoxy. It is not uncommon for a coating to contain several resins, which help the coating perform to specific requirements.
Paint coatings can be classified by function, curing system, volatile components, and resin system.
Function can be described as filler, surfacer, size coat, primer, tie coat and clear coat.
Different types of curing systems include air dry, air dry/force dry, bake/cure, catalyzed, and radiation.
Solvents, waterborne (water based and water reducible) and 100% solids.
