3M Firestop Sealant, 15WB+, 10.1 Oz.

Firestops through penetrations passing through fire-rated floor, floor/ceiling or wall assemblies, as well as other fire-rated interior building partitions and assemblies (eg static construction or blank openings). In addition, the unique intumescent property of this material allows the sealant to expand and help maintain a firestop penetration up to 3 hours as penetrants are exposed to fire. Sealant bonds to most construction substrates, including gypsum wallboard, concrete, metals, wood, plastic including CPVC and cable jacketing. No mixing is required.Helps minimize sound transferSag-resistantHalogen-freeExcellent adhesionRe-enterable/repairableExcellent caulk ratePaintableWater Clean upCPVC compatible
