SYNTEVEN 930 is an isophtalic-modified unsaturated polyester resin in Diallyl phthalate. It is used to formulate styrene free varnish with good reactivity with Redox Cobalt / MEKP catalysis and in hot curing, in the presence of TBPB. The presence of reactive monomer also allows crosslinking by U.V. radiation after the addition of photoinitiator.
