3M CP-25WB+ Fire Barrier Sealant

3M Fire Barrier Sealant CP-25WB+ is ready-to-use, gun-grade, latex-based, intumescent sealant that dries to form a monolithic firestop seal that also acts as a barrier to airborne sound transmission. 3M cp-25WB+ Fire Barrier Sealant 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. The unique intumescent property of this material allows 3M CP-25WB+ to expand and help maintain a firestop penetration seal for up to 4 hours as penetrants are exposed to fire. Exhibits excellent adhesion to a full range of construction substrates and penetrants. No mixing is required.
