GMA 300G

GMA-300G is a highly functional, glycidyl-functional acrylic polymer capable of reacting with carboxyl and amine-functional compounds to form durable coatings.  It can be used either as a sole curing agent for polyesters to make polyester-acrylic hybrids, or as a fortifying additive resin at amounts of 1-5% in systems such as polyester-TGIC or hybrids to boost crosslink density, film hardness and chemical resistance. GMA-300G is ground version of GMA-300.


GMA-300G can also be used in specialized applications such as high temperature powder coating formulations based on polysiloxane chemistry.  See the GMA-300G Technical Brief #1 for details regarding how this product gives better film integrity than TGIC as the polyester curing agent. Dosage of GMA-300G as a crosslinker depends on the equivalent weight of the polyester resin.


As with any raw material, laboratory evaluation is required for each formulation to determine the best processing method and the optimum concentration of GMA-300G.
