ASI 502

High Performance 100% RTV Silicone

INDUSTRIAL & CONSTRUCTION

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 both 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.

Strength will start to develop immediately and continue increasing for 7 days after application. ASI recommends testing strength and adhesion on the 7th day. ASI 502 suggested application temperature range: -35°F to 150°F. ASI 502 can be used at temperatures higher than 400°F for intermittent periods. Testing should be done to confirm temperature requirements are met.
