Product Introduction
Momentive SNAPSIL™ TSE397 is a fast-curing, one-component silicone adhesive sealant that forms an elastic rubber upon exposure to atmospheric moisture. Its non-corrosive formulation—validated by MIL-A-46146B—allows safe use with sensitive metals such as copper. With rapid cure speed, excellent high/low temperature resistance, outstanding environmental durability, low odor, and high electrical insulation, TSE397 is a preferred solution for electronic sealing and assembly tasks.
