G-10 and G-11 Glass Epoxies are used in electrical insulation of appliance lines, electronic lines and mechanic lines. G-10 and G-11 Glass Epoxies are created from electrical alkali-free glass cloth that has been impregnated with an epoxy resin under pressure and heat. G-10 and G-11 possess high mechanical properties at medium humidity and good dielectric stability at high humidity. They are also fire-resistant. G-10 and G-11 can be easily machined and die-cut.
