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 Classifications:
Paint coatings can be classified by function, curing system, volatile components, and resin system.
Function:
Function can be described as filler, surfacer, size coat, primer, tie coat and clear coat.
Curing System:
Different types of curing systems include air dry, air dry/force dry, bake/cure, catalyzed, and radiation.
Volatile Components:
Solvents, waterborne (water based and water reducible) and 100% solids.
Resin System:
Acrylic, Epoxy, Polyester, Polyurethane, Vinyl and PVDF (often referred to as Kynar or Kynar 500. Kynar 500® is not a finished paint, it is a trade name for PVDF (polyvinylidene fluoride) resin, as is Hylar 5000®. Kynar 500® is a registered trademark belonging to Arkema Inc.
