ASI 502 Industrial Silicone Sealant/Adhesive 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 is a non-slump sealant and can be applied to vertical or overhead surfaces without flowing or sagging.Because ASI 502 is a 100% 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 502 can be applied to surface temperatures from -18 Degrees C to +50 Degrees C (0 Degrees F to +120 Degrees F) and after curing, withstands constant operating temperatures from -70 to +400 degrees F.
