3M Fire Barrier Sealant FD 150+ is a gun-grade, latex-based, elastomeric sealant that cures upon exposure to the atmosphere to form a monolithic flexible firestop seal. When properly installed, this sealant helps control the spread of fire, smoke and noxious gasses before, during and after exposure to a fire and exhibits excellent adhesion to a full range of construction substrates.

Tried and Tested Fire Protection
Ready-to-use, 3M™ Fire Barrier Sealant FD 150+ is a latex-based elastomeric sealant. This gun-grade sealant cures when dispensed to form a monolithic flexible firestop seal and, when properly installed, this product provides up to 4-hour fire protection in tested and listed systems. We formulated this sealant to help prevent the spread of fire, smoke and noxious gas and firestop joints and through penetrations through floor slabs, walls and other fire-rated building partitions and assemblies. This firestop sealant offers a continuous seal with ± 19% movement capability for construction joints and typical pipe movement and exhibits excellent adhesion to a full range of construction substrates.

Recommended Applications

• Construction joints
• Piping, all non-combustible and small diameter combustible
• Cables

Fire Barrier Features
3M™ Fire Barrier Sealant FD 150+ acts as an acoustic barrier by minimizing noise transfer (STC-Rating of 56 when tested in a STC 56-rated wall assembly). We designed this fire barrier sealant to be water-based for easy installation, cleanup and disposal. In addition, the high-solids formula produces limited shrinkage. This halogen-free sealant is sag-resistant and has an excellent caulk rate (applied with conventional caulking equipment). It dries to the touch in 30 – 60 minutes and can be painted. In addition, this sealant has been engineered to be re-enterable and repairable.

Designed by 3M, this sealant forms a flexible, monolithic firestop seal that controls fire, smoke, and gas spread. Its gun-grade format ensures smooth application, ideal for various fire-rated building assemblies.

Flexible Sealant Movement Capability

This FD 150+ model features a continuous seal that remains pliable, allowing for typical pipe movement without cracking. Its elastomeric properties accommodate ±19% movement, which is essential for construction joints and penetrations.

Such flexibility helps maintain the integrity of fire barriers over time, especially in dynamic building environments. The limestone color blends well with many substrates, enhancing aesthetic consistency.

High-Solids Formula Benefits

The high-solids formula of this 3M sealant means limited shrinkage after curing, ensuring a durable and lasting seal. This characteristic helps maintain firestop performance and reduces maintenance needs.

Available in a 10.1 fl oz cartridge, the sealant is easy to apply with conventional caulking equipment. Its water-based nature also simplifies cleanup and disposal, making it user-friendly on job sites.

Multi-Viscosity Grade Versatility

The multi-viscosity grade of the FD 150+ sealant offers excellent sealing and caulking properties, suitable for various construction applications. This versatility supports use on different substrates and joint types.

Packaged in a convenient 12-case format, it provides enough material for multiple projects or large-scale jobs, ensuring consistent quality and performance across applications.

Convenient Cartridge Packaging

This fire barrier sealant is supplied in a 10.1 fl oz cartridge, packaged 12 per case, which balances ease of use with efficient supply management. The cartridge format supports precise dispensing and reduces waste.

Its ready-to-use design speeds up installation, while the pack count suits contractors needing reliable quantities for commercial or industrial firestop projects.
