Silicone road sealant


S327 is a one-component, non-sag silicone sealant specially designed for long-lasting weatherproof sealing of expansion joints in airport runways, highways, tunnels, bridges, and other concrete pavements. It features low modulus and good elastic recovery. Accelerated artificial weathering tests show that its excellent weather resistance is fully capable of withstanding the harsh high and low temperature and strong ultraviolet environment of concrete pavements.
