Hypro® 1300X63 ETBN

Hypro® 1300X63 ETBN

Hypro (f.k.a. Hycar®) 1300X63 ETBN is an epoxy-functional synthetic rubber. It is the reaction product of epichlorohydrin and Hypro 1300X13 Carboxyl-Terminated Butadiene-Acrylonitrile copolymer (CTBN).
It is a 100%-solids, reactive polymer designed to incorporate synthetic rubber into a thermoset matrix by reacting it with conventional epoxy hardeners.

Hypro 1300X63 ETBN provides rubber-toughening benefits in 2K epoxy systems and in heat-cured 1K systems.

In 2K systems:
Lower-viscosity alternative to epoxy-resin adducts with CTBNs
Alternative to amine-terminated CTBN where there is incompatibility with the amine co-curatives
Complementary toughener with other toughening agents
