This type of epoxy vinyl ester, using free radical initiators, such as peroxides do hardener after heating can end up with double bond of the vinyl polymerization of crosslinking sclerosis. • Pure epoxy vinyl ester degree of tensile elongation of 3%, heat distortion temperature (HDT) of about 100-120 ° C, associated with hardening of the turn of the increased density, which extends density has decreased, but the HDT increased.Epoxy resin Manufacture
