Seal Bond® 404 - RTV Silicone
SB 404 is a 100% RTV Silicone that is UL & NSF Recognized. SB 404 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. SB 404 100% RTV Silicone is a non-slump sealant and can be applied to vertical or overhead surfaces without flowing or sagging. Because SB 404 is a 100% RTV silicone sealant, it has excellent resistance to weathering including ozone, ultra-violet radiation, freeze-thaw conditions and airborne chemicals.
