ITW Permatex® Black Silicone Adhesive Sealant
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber
Material Notes:	Permatex® Black Silicone Adhesive Sealant (low odor formula) is a general purpose, single component, room temperature vulcanizing (RTV) compound, designed for the sealing of mechanical assemblies. Upon curing from the exposure to moisture in the air, this non-sagging paste forms a tough, flexible, waterproof seal of silicone rubber, which resists aging, weathering and thermal cycling without hardening, shrinking or cracking. Not recommended for engine gasketing applications or windshield installation. Permatex® Black Silicone Adhesive Sealant cures on exposure to moisture in the air. The product dries tack free in 1 hour and fully cures in 24 hours. Cure times will vary with temperature, humidity and gap. Information provided by ITW Performance Polymers.
