Ic 15wb+ Fire Barrier Sealant, Yellow, 10.1 Oz.

The 3M IC 15WB+ Fire Barrier Sealant is a yellow, one-part, gun-grade, intumescent firestop sealant designed to protect wall and floor penetrations from fire, smoke, and noxious gases. This water-based sealant forms a monolithic seal after drying and expands during a fire to maintain a tight barrier against flames and smoke, making it essential for both residential and commercial applications where fire safety and code compliance are critical.

This versatile sealant bonds effectively to a variety of materials including concrete, metal, wood, plastic, and cable jacketing. Beyond fire protection, it also functions as an acoustic barrier to help minimize noise transfer between spaces. The bright yellow color makes it easily recognizable on job sites, and the water-based formulation allows for simple cleanup with soap and water, saving time and reducing waste.
