CVC Thermoset Specialties Introduces Epoxy Toughening Agent for -40 °C Automobile Adhesives

MOORESTOWN, NJ., October 24, 2019— CVC Thermoset Specialties, an Emerald Performance Materials company, introduces HyPox® RA875, its newest carboxyl-terminated acrylonitrile-butadiene (CTBN) epoxy adduct toughening agent. HyPox RA875 enables improved peel strength at room temperature and temperatures down to -40°C and enhanced adhesion to oily substrates when compared to core-shell rubber (CSR).

A clean, dry surface is crucial to the performance of adhesives. However, automotive applications often have constraints that make fully cleaning a substrate impossible. When formulated with HyPox RA875, automotive structural adhesives demonstrate improved adhesion to oily substrates. HyPox RA875 reduces rejections due to adhesive failure, which improves production.

HyPox RA875 also helps to strengthen adhesives. It maintains excellent properties of high crosslink density such as high modulus and failure strength, excellent adhesive strength, and low creep — while reducing the brittleness of the epoxy. Adhesives with HyPox RA875 demonstrate improved peel strength when used on electro-galvanized steel, aluminum and hot-dipped galvanized steel.

HyPox RA875 is part of CVC Thermoset Specialties’ line of elastomer-modified epoxy resins designed to merge the benefits of CTBN-toughened chemistry with the convenience of conventional 1- or 2-part epoxy handling and performance.
