Product Introduction
Momentive SNAPSIL™ RTV102 is a one-component, paste-consistency silicone adhesive sealant designed for general-purpose bonding and sealing applications. It cures at room temperature into a tough, durable silicone rubber and provides excellent electrical insulation, weatherability, and resistance to high and low temperatures. RTV102 is suitable for vertical and overhead surfaces and is widely used for formed-in-place gaskets, sealing, and electrical insulation tasks.
