3M 7000059394 Fire Barrier Sealant Cp 25WB+ 27 Oz

Product Description

The 3M 7000059394 is a latex-based intumescent firestop sealant designed to seal penetrations through fire-rated construction assemblies. When properly installed in tested and listed systems, it provides up to 4-hour fire protection. The sealant is water-based, requires no mixing, and dries to a red color for easy visual inspection. It helps prevent the spread of fire, smoke, and noxious gases through wall and floor penetrations. This product is installed by licensed firestop contractors, journeyman electricians, plumbers, and mechanical contractors working on commercial or multi-family residential construction.

This sealant is applied in fire-rated wall and floor assemblies where pipes, conduit, cable trays, ducts, and other building system components penetrate fire-rated barriers. It is suited for both new construction and retrofit applications. The product meets International Building Code requirements and other key life safety building code standards. It also meets the intent of LEED VOC environmental regulations, making it appropriate for green building projects. When installed in an STC 54-rated wall assembly, it achieves an STC rating of 54, providing an acoustic barrier that minimizes noise transfer between occupied spaces.
