Our 3M? fire barrier sealant FD 150+ is a gun-grade, latex-based, elastomeric sealant that cures upon exposure to the atmosphere to form a monolithic flexible firestop seal. When properly installed, this sealant helps control the spread of fire, smoke and noxious gasses before, during and after exposure to a fire and exhibits excellent adhesion to a full range of construction substrates.

Engineered to form a monolithic seal after drying, 3M Fire Barrier Sealant IC 15WB+ is a yellow, one-part, gun-grade, intumescent firestop sealant that provides up to 3 hr fire protection in tested and listed systems. This helps prevent the spread of fire, smoke and noxious gas, while also acting as an acoustic barrier to help minimize noise transfer.
