EVOLUTION 2590-3 is a 1:1 by volume, slow curing polyurethane resin. It is designed to be sprayed with chopped glass and cures to a hard and durable coating. When used for fiber reinforcement a minimum thickness of 80 mils is recommended. Gel time is affected by thickness application. The thicker it is applied, the faster it will cure.
