It cures to a durable, flexible rubber that withstands extreme temperatures (-70°F to +400°F) and harsh weathering, while adhering to a wide range of materials including glass, metal, wood, and plastics. FDA-approved for incidental food contact, its sleek black finish blends seamlessly on dark surfaces, making it the go-to choice for both industrial and kitchen applications. ## 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. Review: Very Easy to Use - This silicone is easy to apply. You do not need a caulk gun or any other tool. You apply it straight from the tube. I found it to be very clean. It has a semi-gloss to satin presentation when dried. I used it to fill some gaps in some black painted wood that I put together and it was perfect. It blended right in with the pained wood. It adhered to the wood very well and filled the gaps seamlessly. It looks great. Review: Great for kitchen sink seal! - Worked great for our below kitchen sink which is black on black granite. Can't see the seal like the clear silicon that the installers used. be mindful if you use it for this, remember to clean occasionally! ## Features - 100% RTV Silicone is a non-slump sealant and can be applied to vertical or overhead surfaces without flowing or sagging - one-part, moisture-curing RTV (room temperature vulcanizing) silicone that cures to a strong, silicone rubber that maintains long-term durability and flexibility - excellent resistance to weathering including ozone, ultra-violet radiation, freeze-thaw conditions and airborne chemicals - Fully cured, it has an excellent adhesion to glass, metal, porcelain, ceramic, wood, most plastics and many other nonporous substrates - permitted under regulations of the Food and Drug Administration where incidental food contact might be involved.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very Easy to Use *by G***T on July 4, 2025* This silicone is easy to apply.
