Product Introduction
Momentive SNAPSIL™ RTV116 is a one-component, self-leveling silicone adhesive sealant formulated for high-temperature performance within the RTV100 Series. It cures at room temperature when exposed to atmospheric moisture, forming a tough and resilient silicone rubber. RTV116 flows into tight crevices and small voids, making it ideal for applications requiring a flowable sealant. Designed for section depths below 6 mm (¼ inch), it provides excellent weatherability, ozone resistance, chemical resistance, and reliable electrical insulation.
