Cp 25wb+ Fire Barrier Sealant, Red, 10.1 Oz. Cartridge

3M Fire Barrier Sealant CP 25WB+ is a one-component, latex-based, intumescent firestop sealant designed to seal penetrations in fire-rated walls, floors and joints. This ready-to-use sealant dries to form a monolithic firestop seal that helps control the spread of fire, smoke and noxious gases before, during and after exposure to fire. When exposed to heat, the sealant's intumescent properties cause it to expand, helping maintain the integrity of the firestop penetration seal for up to 4 hours.

In addition to its firestop capabilities, this sealant also reduces airborne sound transmission, making it useful for creating quieter interior spaces. The one-component, gun-grade formula is ready to apply directly from the cartridge, simplifying field installation and reducing preparation time on the job site.
