Glycidyl Methacrylate
CAS Number: 106-91-2
Glycidyl methacrylate (GMA) is an epoxy-functional methacrylic monomer that introduces reactive oxirane groups into polymer backbones. GMA-containing copolymers can be thermally or acid-crosslinked through epoxy ring-opening reactions, making them ideal for powder coating binders, reactive compatibilizers, and self-crosslinking latex systems.
