3M 7100006311 Fire Barrier Sealant Cp 25WB+ 2 Gallon

Product Description

The 3M 7100006311 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 hours of fire protection. The sealant dries to a red color for easy visual inspection and requires no mixing. It helps prevent the spread of fire, smoke, and noxious gases through penetration points, making it a code-critical material for commercial and residential construction. Licensed contractors and fire protection installers apply this product as part of a complete firestop system.

This sealant is used in fire-rated wall and floor assemblies where pipes, conduit, cable trays, and other items penetrate rated construction. It serves as both a firestop and an acoustic barrier, achieving an STC rating of 54 when tested in an STC 54-rated wall assembly. It also supports smoke-seal requirements for systems requiring an optional L-Rating. The 2-gallon pail format suits multi-penetration commercial jobs and larger residential projects where volume application is required.

Installation Notes

Installation must be performed by a qualified firestop contractor or licensed tradesperson in accordance with the specific tested system design and applicable building codes, including IBC requirements.
