3M Fire Barrier Sealant IC 15WB+, Yellow, 4.5 Gallon (Pail)

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-hour 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.

Establish a Strong Firestop Barrier
​Designed to prevent the spread of fire, smoke and noxious gas, 3M™ Fire Barrier Sealant IC 15WB+ is a one-part, gun-grade, latex-based, intumescent firestop sealant. This firestop sealant provides up to 3-hour fire protection in accordance with ASTM E 814 (UL 1479) and CAN/ULC S115. In addition, this product is fire resistance tested for static construction joint systems in accordance with ASTM E 1966 (UL 2079). This sealant has been formulated to form a monolithic firestop seal that also helps minimize sound transfer, acting as a barrier to airborne sound transmission (STC-Rating of 54 when tested in a STC 54-rated wall assembly).
