3M 7000145569 Cp 25WB+ Firestop Sealant 20 Fl Oz

Product Description

The 3M 7000145569 is a latex-based intumescent firestop sealant designed for use in fire-rated construction assemblies. When properly installed in tested and listed systems, it provides up to 4-hour fire protection. The sealant expands under heat to block the spread of fire, smoke, and noxious gases through penetrations in fire-rated walls, floors, and ceilings. It dries to a red color for easy visual inspection and requires no mixing. It also functions as an acoustic barrier, achieving an STC rating of 54 when tested in an STC 54-rated wall assembly.

This product is suited for commercial and residential construction where penetrating items such as conduit, pipe, cable, and duct pass through fire-rated assemblies. It is installed by licensed contractors, fire protection specialists, and journeyman tradespeople working on new construction or retrofit projects that must meet International Building Code requirements and other life-safety code mandates. The sausage-style packaging is compatible with standard bulk sausage guns for controlled application in confined penetration openings.
