Application

Pyromellitic dianhydride glycerol dimethacrylate (PMGDM) is an adhesive monomer synthesized from pyromellitic dianhydride and glycerol dimethacrylate. As a mixture of the para- and meta isomers, PMGDM has several advantages over more traditional adhesive monomers. PMGDM can be applied in thicker layers, and additives and/or additional initiators to improve curing can be readily incorporated.
