HyPox RF933
HyPox RF933
HyPox RF933 adduct is an epoxy phenol novolac resin modified with CTBN. This product has a functionality of 2.6 and an elastomer content of 20%. The rubber improves the toughness of cured epoxy formulations through the development of two phases during cure. Compared to DGEBA (EEW 188 g/eq) modified at an equal rubber level, HyPox® RF933 adduct should provide improved chemical and heat resistance because of its higher functionality. Formulations incorporating this adduct will exhibit improvements in impact and thermal cycling resistance, peel, and tensile shear strengths, and low-temperature mechanical properties compared to non-rubber-modified epoxy formulations.
This adduct should be considered for use as the sole resin or as a part of the resin component of your formulation. The optimum concentration of HyPox RF933 adduct should be determined empirically. Typical applications generally incorporate 5-15 phr (parts per hundred parts resin) rubber to achieve optimal toughness; higher concentrations improve flexibility.
