Epoxy encapsulants

Epoxy is used to cast in and protect electronics when high chemical resistance is needed or when gas tightness and low moisture absorption in the casting compound is desired. Epoxy products with fire protection classification up to UL94-V0, thermally conductive and in heat class up to class F. Transparent materials are also available for LEDs. Most epoxies used for potting are 2-component materials that cure at room temperature. For higher temperature and chemical resistance, the epoxy is usually heat-curing, possibly two-component or one-component.
