EPALLOY 8350 is a 3.6 functional epoxy phenol novolac resin exhibiting slightly higher viscosity than CVC’s standard high functionality resin.  This version incorporates slightly higher advancement as measured by EEW and hydroxyl content. EPALLOY 8350 combines low hydrolyzable chlorides with good reactivity.  It is non-crystallizing and compatible with all standard curing agents and most resin systems and solvents.  Because of its high functionality, EPALLOY 8350 is excellent for use in hot melt prepreg, filament winding and circuit board applications where high temperature performance is required.
