Epoxy Resins

July 18th Fact-of-the-Day

Epoxy resins are a family of thermosetting resins widely used in potting, casting and encapsulating electrical and electronic components because of their excellent electrical properties, dimensional stability, resistance to high temperatures, resistance to attack by a wide range of corrosive chemicals, and their strong adhesions to metal, glass, fibers, and other materials. Epoxy resins are cured by catalysts that promote self-polymerization or by cross-link agents known as hardeners. Most of the curing materials are liquids of moderately low viscosity that can be blended with resins at room temperature which makes potting and encapsulating electronic components relatively easy. Commercially-encapsulated components range from miniature switches and coils to large motors, transformers, insulators, and other components weighing several pounds. ©2005 Martek International All rights reserved.
