Hypro® Epoxy-Functional Butadiene-Acrylonitrile Polymers (formerly Hycar® ETBN)

Hypro 2000X174, 1300X68 and 1300X63 are glycidyl-esters of  butadiene (ETB) and butadiene-acrylonitrile (ETBN) co-polymers incorporate 100% rubber toughening into epoxy matrix without pre-reaction or additional epoxy resin.  Excellent for epoxy composites and adhesives.  Contains no Bisphenol A.  These products are developmental and specification ranges are subject to change based on manufacturing history.

Hypro 1300X40 and 1300X44 ETBN are epoxy-terminated butadiene-acrylonitrile (ETBN) resin adducts with no excess epoxy.  The Hypro ETBN have much higher rubber content when compared to HyPox CTBN-modified epoxies.
