A lacquer is usually defined as a solution of organic film forming material (s) in organic solvent (s) from which the solvent evaporates, during and after application to a substrate, and in which the drying mechanism is solely via evaporation. Films of true lacquers stay permanently soluble in similar solvents to those used as a ‘carrier’ for the film-forming components. The binder in these non-convertible coatings remains thermoplastic, in contrast to convertible coatings which thermoset due to chemical reaction.
