Epoxy resin E732

for composites

E732 is a snap cure toughened epoxy resin matrix optimized for press curing (compression molding) prepreg applications. With a cure time of 4 minutes at 160°C (320°F), an onset Tg of 170°C (338°F) is achieved. At this higher temperature, medium to high production rates can be accomplished, with customers’ able to produce beyond 50,000 parts per year. Toray E732 is a versatile matrix with a range of processing options allowing a variety of automotive and industrial applications to be realized.
