Product Introduction
Momentive SNAPSIL™ TSE387 is a one-component, oxime-curing silicone adhesive sealant that cures at room temperature into a flexible, elastomeric rubber. Its flowable consistency enables easy dispensing and strong primerless adhesion to metals, plastics, ceramics, and glass. With excellent electrical insulation, weatherability, chemical resistance, and versatility, TSE387 is ideal for sealing, coating, potting, and bonding in industrial and electronic applications.
