ABSTRACT:
An improved durable, low density, high build polyurethane coating is disclosed, as well as its method of manufacture. A slow reacting polyisocyanate is combined with a polyol so as to form a uniform mixture with an extremely long pot life. The low viscosity uniform mixture can then be sprayed onto a substrate using a conventional spray gun. A polyurethane catalyst is introduced after formation of the uniform mixture, preferably via a second spray nozzle so that catalyst is externally mixed into the polyisocyanate/polyol spray stream. This is a 100%, or near 100%, solids system so that there is very low volatile organic compound emissions.
