Lacquer & Varnish Information Lacquer is a fast drying coating that cures strictly by solvent evaporation. It can contain any number of different resins including cellulose nitrate, CAB, vinyl, acrylic and polyurethane to name a few. Varnish is oil cooked with resin that cures by oxidative polymerization. It too can contain many different resins both synthetic and natural including the two most common ones alkyd and polyurethane. Polyurethane is shorthand that refers to a resin, not a finish. Polyurethane resins are used in oil varnishes, waterbased coatings, lacquers and cross-linking finishes which are often referred to simply as "polyurethane". All are durable, time proven products.
