SINOMER® GMA is a monomer contains acrylate's "C=C"bond and Epoxy Group. With the high reactivity of "C=C", it can be autopolymerizated, or polymerizated with many other monomers;with Epoxy group, it can take reaction with hydroxy-group, amino-group, carboxyl-group or anhydrides, in order to have more functional groups enter into products for more functions.
