ASI 504

Multi-Purpose RTV Silicone


ASI 504 Multi-Purpose RTV Silicone 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 504 RTV Silicone contains no solvents or isocyanates which makes it VOC compliant. Due to the formulation, ASI 504 RTV Silicone Sealant works well for a variety of applications. ASI 504 RTV Silicone is a non-slump sealant and can be applied to vertical or overhead surfaces without flowing or sagging. ASI 504 Multi-Purpose RTV Silicone also has excellent resistance to weathering including ozone, ultra-violet radiation, freeze-thaw conditions and airborne chemicals. ASI 504 Multi-Purpose RTV Silicone 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 -57°C to +205°C (-70°F to 400°F).
