EPALLOY® 8330
EPALLOY 8330 is a 3.6 functional epoxy phenol novolac resin exhibiting lower viscosity than competitively available commercial alternates. Close process controls produce a resin significantly lower in viscosity than other epoxy novolacs of similar functionality. EPALLOY 8330 combines low hydrolyzable chloride content with good reactivity. It is non-crystallizing and compatible with all standard curing agents and most resin systems and solvents. Because of its lower viscosity, EPALLOY 8330 is excellent for use in hot melt prepreg, filament winding and circuit board applications where high performance is required.
