3M 7000006379 Fire Barrier Sealant Cp 25WB Plus 5 Gal

Product Description

The 3M 7000006379 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 delivers up to 4-hour fire protection. The sealant expands when exposed to heat, blocking the spread of fire, smoke, and noxious gases through wall and floor openings. It dries to a red color for easy inspection and requires no mixing before application. With an STC rating of 54 when tested in an STC 54-rated wall assembly, it also serves as an acoustic barrier, minimizing noise transfer between compartments. This product is suited for installation by licensed contractors, firestop specialty installers, and mechanical or electrical trades working in commercial and residential construction.

This sealant is used to firestop through-penetrations in fire-rated walls and floor assemblies where cables, conduit, pipe, and other items pass through rated construction. It meets International Building Code requirements and other key life safety building code standards. The low-VOC, water-based formula meets the intent of LEED VOC environmental regulations, making it appropriate for green building projects. It is applicable in both new construction and retrofit firestop applications where code compliance and system listing are required.
