We formulated this fire sealant to dry and form a monolithic firestop seal that also acts as a barrier to airborne sound transmission. 3M™ fire barrier sealant CP 25WB+ is a red, 1-component, gun grade, latex based, intumescent firestop sealant. This fire barrier sealant helps control the spread of fire, smoke and noxious gases before, during and after exposure to a fire. Tough and ready to use, 3M™ fire barrier sealant CP 25WB+ is a high performance, 1-component, latex based, intumescent sealant that dries to form a monolithic firestop seal. This sealant also acts as a barrier to airborne sound transmission. As penetrants are exposed to fire, the unique intumescent property of this material allows 3M™ fire barrier sealant CP 25WB+ to expand and help maintain a firestop penetration seal for up to 4 hours. This sealant is designed to help control the spread of fire, smoke and noxious gases before, during and after exposure to a fire when installed in accordance with a listed through-penetration or fire-resistive joint assembly system (STC-Rating of 54 when tested in a STC 54-rated wall assembly). 3M™ fire barrier sealant CP 25WB+ firestops blank openings and penetrations passing through fire-rated floor, floor/ceiling or wall assemblies and other fire-rated interior building construction. This halogen-free sealant is capable of expanding a minimum of 3 times its dried volume when exposed to temperatures above 1000 deg f (538 deg C). We engineered this sag-resistant sealant to exhibit strong adhesion to a full range of construction substrates and penetrants.
