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.
