Product Description
Engineered to form a monolithic seal after drying, 3M Fire Barrier Sealant IC 15WB+ is a yellow, one-part, gun-grade, intumescent fire-stop 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. 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).
3M Fire Barrier Sealant IC 15WB+ is easily cleaned-up with water. This sealant is paintable, as well as re-enterable and repairable. It is a halogen-free sealant that features exceptional adhesion, excellent caulk rate and sag-resistance. In addition, inspectors can instantly recognize 3M Fire Barrier Sealant IC 15WB+ by its distinctive yellow color.
3M Fire Barrier Sealant IC 15WB+ firestops through penetrations passing through fire-rated floor, floor/ceiling or wall assemblies, as well as other fire-rated interior building partitions and assemblies (e.g. static construction joints or blank openings). In addition, the unique intumescent property of this material allows 3M Fire Barrier Sealant IC 15WB+ to expand and help maintain a firestop penetration seal for up to 3 hours of fire exposure. 3M Fire Barrier Sealant IC 15WB+ bonds to most construction substrates, including: gypsum wallboard, concrete, metals, wood, plastic and cable jacketing. This sealant meets the intent of LEED VOC environmental regulations, International Building Code (IBC) and other key life safety building code requirements.

Application Instructions
Surface Preparation: Surfaces to be sealed or bonded should be clean and dry. Surfaces should be free from grease, mold release, oil, water/condensation, and other contaminants that may affect the adhesion of the sealant. Abrading with 180 to 220 grit abrasive followed by a solvent wipe will improve the bond strength. Suitable solvents include 3M Adhesive Remover or methyl ethyl ketone (MEK).
* Multiple cases may be shipped per package in order to minimize the charge for shipping.
