Hypro® 2000X174 ETB
Hypro (f.k.a. Hycar®) 2000X174 ETB is an epoxy-functional synthetic rubber. It is the reaction product of epichlorohydrin and Hypro 2000X162 Carboxyl-Terminated polybutadiene (CTB).
It is a 100%-solids, reactive polymer designed to incorporate synthetic rubber into a thermoset matrix by reacting it with conventional epoxy hardeners.
