Electrical Systems

Epotec® Epoxy Systems are best known for casting into molds, cavities, cores and patterns. They are also extensively used for encapsulation, impregnation and protection of electrical and electronic assemblies and components. Usually low-pressure-reacted resins are utilized and curing is performed at room temperature to elevated temperature, up to 200°C. Room temperature curing Epotec® Systems are preferred for low voltage, small components, while heat-cured Epotec® Systems offer extremely high physical, thermal and chemical resistance. As such, heat-cured Epotec® Systems are used for medium and high voltage applications.
