The 3M 7010353044 is a non-slump, single-component, neutral-cure elastomeric silicone firestop sealant designed to seal penetrations in fire-rated wall and floor assemblies. It delivers up to 3-hour fire protection against the spread of fire, smoke, and noxious gas in tested and listed systems. The sealant also meets UL Water Leakage Test W Rating Class 1 requirements per ANSI/UL 1479, providing a watertight barrier at penetration points. With an STC rating of 56 when tested in an STC 56-rated wall assembly, it also reduces airborne sound transmission. Ready to use with no mixing required, it ships in a 20 fl oz sausage-style package in light gray color.
This sealant is used in commercial and residential construction where building codes require firestopping at penetrations through fire-rated assemblies. Typical applications include pipe, conduit, cable, and duct penetrations through rated walls and floors. It is suited for projects requiring compliance with International Building Code life safety requirements and installations where W Rating and optional L Rating smoke-seal performance are specified. It also meets the intent of LEED VOC environmental regulations, making it appropriate for green building projects.
Designed for use in tested and listed firestop systems per ANSI/UL 1479 for penetrations through fire-rated wall and floor assemblies including pipes, conduit, cables, and ducts.
Installation should be performed by a qualified firestop contractor or trades professional familiar with applicable building and fire codes, including IBC requirements. Clean and prepare the substrate per the tested system design before applying sealant. Do not apply over wet or contaminated surfaces. Verify the specific tested and listed system design for the penetration type and assembly rating before installation to ensure code compliance.
