3M 2000+ Fire Barrier Silicone Sealant

3M Fire Barrier Silicone Sealant 2000+ is a ready-to-use, gun-grade, one-component silicone elastomer that cures upon exposure to atmospheric humidity to form a flexible firestop seal. This material helps control the spread of fire, smoke and noxious gasses before, during and after exposure to afire when installed in accordance with a listed through penetration or fire-resistive joint assembly. 3M Fire Barrier Silicone Sealant 2000+ firestops dynamic construction joints, blank openings and penetrations passing through fire-rated floor, floor/ceiling or wall assemblies and other fire-rated interior building construction. The sealant remains elastomeric, bonds to most common construction materials and exhibits excellent weatherability during construction. No mixing is required.Information provided by 3M
