RTV SILICONE ADHESIVES
RTV Silicone, or Room-Temperature-Vulcanizing silicone, is a type of silicone rubber adhesive used for numerous sealing and bonding applications. There are many variations of RTV silicone that offer different characteristics specific to the most challenging applications. GRR offers the following series of RTV Silicone adhesives.
The ASI 502 100% RTV Silicone is a one-component, moisture cure, acetoxy silicone that cures to form an extremely durable rubber that can withstand a variety of extreme environments. Unlike many organic sealants, ASI 502 is extremely resistant to degradation, weathering, extreme temperatures, and mold and mildew. ASI 502 meets the requirements of NSF Standard 51 and FDA Regulation No. 21 CFR 177.2600 for food grade applications. ASI 502 100% RTV Silicone can be applied to bother vertical and overhead joints without sagging and is easy to extrude at both hot and cold temperatures. It will adhere to most common building materials as well.
