The 3M Fire Barrier Sealant CP 25WB+ is a latex-based sealant designed to firestop openings in fire-rated constructions. It comes in a twenty-ounce sausage pack and can be applied with standard caulking tools. This sealant dries to a solid form, which reduces sound transmission.
This sealant expands when heated, forming an effective barrier against fire, smoke, and gases.
