3M CP 25WB+ Fire Barrier Sealant
Categories:	Polymer; Thermoset
Material Notes:	3M Fire Barrier Sealant CP 25WB+ is a high-performance, ready-to-use, gun-grade, latex-based, intumescent sealant that dries to form a monolithic fire-stop seal that also acts as a barrier to airborne sound transmission. 3M Fire Barrier Sealant CP 25WB+ helps control the spread of fire, smoke and noxious gasses before, during and after exposure to a fire when installed in accordance with a listed through penetration or fire-resistive joint assembly system. 3M Fire Barrier Sealant CP25WB+ firestops blank openings and penetrations passing through fire-rated floor, floor/ceiling or wall assemblies and other fire-rated interior building construction. The unique intumescent property of this material allows 3M Fire Barrier Sealant CP25WB+ to expand and help maintain a firestop penetration seal for up to 4 hrs as penetratants are exposed to fire. 3M Fire Barrier Sealant CP25WB+ exhibits excellent adhesion to a full range of construction substrates and penetrants. No mixing is required. Information provided by 3M
