WebVESTANAT® EP-DC 1241 is a heterofunctional monomer, comprising both, an isocyanate group and an acrylic function. It is based on isophorone diisocyanate (IPDI) and a hydroxyfunctional acrylate. VESTANAT® EP-DC 1241 is characterized by a very low content of di-adduct and monomeric IPDI. This allows for a very selective synthesis of the resin ...
