3M FD 150+ Blue Fire Barrier Sealant, Blue, 40 to 122 deg F, 10.1 oz Cartridge

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.
