Hypro™ Reactive Liquid Polymers

Hypro™ Reactive Liquid Polymers (RLP) feature carboxyl, amine and methacrylate vinyl reactive functional groups. The letter designations below are the key to the RLP product nomenclature. Hypro polymers are 3,000-4,000 molecular weight liquids that vary in acrylonitrile and butadiene content. Acrylonitrile will increase resin compatibility, viscosity and raise Tg. Reactive liquid polymers are used as co-reactants in thermoset systems. At low levels they function as tougheners, improving impact resistance and peel strength while maintaining mechanical and thermal properties. At higher levels they provide high elastomeric properties tothermoset materials.

HyPox™ Elastomer Modified Epoxy Resins

Elastomer modification to epoxy resins is a valuable way to merge the benefits of alternate polymer chemistry with the convenience of conventional 1 or 2 part epoxy handling and performance. Currently, CVC offers CTBN modification for toughening and chip resistance, Dimer Acid modification for flexibility and Urethane modification for adhesion to difficult surfaces. These are grouped under the series designation:
 D Series - Dimer Acid Modified Epoxy Resins
 U Series - Urethane Modified Epoxy Resins
 R Series - CTBN Modified Resins
Each resin system is further divided by resin base:
“A” for Bisphenol A, “F” for Novolacs and “M” for Glycols

Compact tension specimens exemplify toughening. Stress whitening is
seen in the sample with HyPox™ indicative of a toughened system.
The sample without HyPox does not demonstrate any stress whitening,
thus is quite brittle.
