HYPOX® RF 928 N

HYPOX® RF 928 N Adduct is an epoxy phenol novolac resin toughened with a CTBN (carboxyl-terminated butadiene-acrylonitrile) co-polymer. With a low viscosity, a functionality of 2.3, and 20% elastomer content, it enhances toughness without significantly affecting Tg. Formulations with this adduct show improved impact, thermal cycling, peel, tensile shear strengths, and low-temperature properties. It also offers better chemical and heat resistance than DGEBA-toughened epoxies at the same rubber level.
