Synthetic enamel paints are based on the alkyds/drying oils which have hard films with gloss retention. The films show excellent brushing properties and little tendency to yellowing on exposure to the environment. The pigment volume concentration controls the gloss, washability, adhesion and durability. The drying may occur at room temperature by oxidation and polymerization. Used on various substrates like wood, metal, train coaches, automobiles industries etc.
