ASI aquarium sealant 502 is a 100% RTV Silicone that is UL & NSF Recognized. ASI 502 is a one-part, moisture-curing RTV (room temperature vulcanizing) silicone for aquarium 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 industrial applications where a long-term, permanently flexible bond or seal is required.
