| ADIPRENE LW 520 is a polyether-based liquid casting urethane polymer, prepared with an aliphatic diisocyanate, that yields tough, high quality elastomers in the 90 durometer A hardness range when cured with methylene dianiline. It is readily processable by conventional hand and machine mixing techniques. |
