| Paint Components: The three main components of an (organic) paint coating are:
Pigment:
provides opacity, color (also can provide corrosion resistance, water barrier
properties, viscosity control, etc.); primer coatings are sometimes named after a pigment,
for example zinc-rich primer.
Binder (resin):
binds the ingredients (holds everything together), forms the film; also known as
the non-volatile vehicle; paint coatings are often named after the resin, for example
epoxy, vinyl, polyurethane, acrylic, etc.
Volatile vehicle (solvent or dispersant):
dissolves or disperses the binder, allows the coating to spread out.
A distinction can be made between a non-convertible
coating (cures by evaporation of the solvent without a chemical change to the resin) and a
convertible coating (cures by a chemical change in the resin,
polymerization).
