What is catalyzed urethane?
Catalyzed urethane is a product that is made primarily from urethane resin. This product also hardens primarily by chemical reaction. Unlike the epoxies, it weathers very well and is used as a premium top coat. As both of the above products “dry” by chemical reaction and not evaporation the over spray will stay wet longer and greater care is required in protecting the surroundings from overspray.
