Product Introduction
Momentive TSE3941W is a one-component, non-corrosive silicone adhesive sealant that cures upon exposure to atmospheric moisture, forming a durable, elastic, and flame-retardant silicone rubber. Engineered with low volatility and low odor, it delivers excellent adhesion to many substrates while maintaining strong mechanical and electrical properties. Recognized under UL94V-0, TSE3941W is suitable for applications requiring reliable sealing, bonding, and environmental resistance.
