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. It helps control the spread of fire, smoke, and noxious gases before, during, and after exposure to a fire, with excellent adhesion to a full range of construction substrates.
This sealant has been firestop tested up to 3 hours according to ASTM E 814 (UL 1479) and CAN/ULC S115, and fire resistive joint systems up to 4 hours per ASTM E 1966 (UL 2079). Its high-solids formula ensures limited shrinkage and remains pliable, allowing for typical pipe movement. Water-based for easy installation, cleanup, and disposal. Re-enterable and repairable, it offers a reliable fire barrier solution for commercial and industrial applications. Ships tracked via ExpressBox, duties included, arrives in 11-13 days.
