## Description

ASI 502 is a 100% RTV Silicone that is UL & NSF Recognized. ASI 502 is a one-part, moisture-curing RTV (room temperature vulcanizing) silicone that cures to a strong, silicone rubber that maintains long-term durability and flexibility. ASI 502 100% RTV Silicone is a non-slump sealant and can be applied to vertical or overhead surfaces without flowing or sagging. Because ASI 502 is a 100% RTV silicone sealant, it has excellent resistance to weathering including ozone, ultra-violet radiation, freeze-thaw conditions and airborne chemicals. Fully cured, ASI 502 has excellent adhesion to glass, metal, porcelain, ceramic, wood, most plastics and many other nonporous substrates. ASI 100% RTV Silicone (ASI 502) can be applied to surface temperatures from -18°C to +50°C (0°F to +120°F) and after curing, withstands constant operating temperatures from -70 to +400 degrees F. Typical Uses: ASI 502 is an excellent sealant and/or adhesive for many applications where a long-term, permanently flexible bond or seal is required.

## Questions & Answers

**Q: Is it microwave-safe?**
A: yes but it doesn't taste very good when heated

**Q: is this conductive?**
A: You don't need heat for it to seal, if this is what you were asking.

**Q: Can this be used on granite counter top seam?**
A: We used it successfully between our granite counter and our cooktop.

**Q: Don't want an adhesive, but to make a gasket to seal the lid of a pot, and keep steam in. Will this product adhere to only one object after curing?**
A: Yes, you can use this as a gasket maker.   I put a thick bead on the frame to the door of my smoker, kept the door open for a couple days so it cured, and now have a very tight seal when the door is shut.
