Ther-O-Bond 1500 is a versatile epoxy casting system developed for high performance, production potting and encapsulating applications where low shrinkage and rapid air evacuation are required. This formulation has a very low surface tension and a flowable viscosity, which affords excellent air release. Ther-O-Bond 1500 adheres to rigid plastics and laminates, metals and ceramics, has a low coefficient of thermal expansion and is readily machined and shaped with ordinary shop tools. Black in color, the fully cured epoxy system is an excellent electrical insulator which provides good resistance to electrolysis, leakage and corrosion from water, weather, gases and chemical compounds.
