Durable Dielectric Molding Compounds

GRE EPO-TEC continues to innovate thermoset epoxy formulations to achieve new standards of toughness, impact strength, and moisture resistance. Our molding compounds are an excellent choice for the most challenging environments where electrical devices are subject to corrosives, chemicals, heat and shock.

We have also developed "green" formulations with low thermoset temperatures and fast cure rates to lower the cost of molding.
