Epotec® Epoxy Resins for Electrical Applications is best-known for castings into mold, cavities, cores and patterns. They are also extensively used for encapsulation and protection of electrical and electronic components. Room-temperature curing resins are preferred for low voltage, small components, while heat-cure resins offer extremely high physical, thermal and chemical properties and used for medium and high voltage applications in electrical and electronic industries.
