BX-51 Urethane Elastomer
BX-51 is a two-part polyurethane molding system. BX-51 is mixed 100:97 by weight (or 1 Part-A Iso to 1 Part-B Curative by volume) and cures at room temperature. BX-51 cures to a high hardness, Shore A 50 2, gray rubber. Ultimate properties are obtained after 3-4 days of room temperature cure.
