Product Introduction
Momentive SILTRUST™ TSE3663 is a two-component, condensation-cure silicone potting material designed for electronic applications. It cures at room temperature to form an elastic, durable rubber that offers primerless adhesion to metals, plastics, ceramics, and glass. With low viscosity, excellent dielectric strength, and strong deep-section curing, it provides reliable protection for sensitive electronic assemblies.
