3M Fire Barrier IC 15WB+ Sealant :
Intumescent Firestop Protection
Intumescent Firestop Protection
- 3M™ Fire Barrier Sealant IC 15WB+ is a one-component, latex-based, intumescent firestop sealant that expands when exposed to high temperatures, helping prevent the spread of fire, smoke, and harmful gases through service penetrations and building openings.
- This easy-to-apply, gun-grade sealant dries to form a durable, monolithic fire barrier while also reducing airborne sound transmission. It is suitable for a wide range of mechanical, electrical, and plumbing (MEP) applications and adheres to most common construction materials, including concrete, gypsum board, metal, wood, plastic pipes, and cable jackets.
- Engineered for both new construction and retrofit projects, it provides up to 3 hours of certified fire protection and supports compliance with international building and fire safety standards.
Key Features of
3M Fire Barrier Sealant
Up to 3 Hours Fire Resistance
Provides certified fire protection for penetrations and joints in fire-rated assemblies for up to 3 hours.
Intumescent Technology
Expands when exposed to high temperatures to seal gaps created by melting combustible materials.
Excellent Acoustic Performance
Acts as a sound barrier with an STC rating of up to 54 when installed in tested wall assemblies.
Re-Enterable and Repairable
Allows future cable additions, maintenance work, and modifications with minimal disruption.
Easy Water Cleanup
Tools and excess material can be cleaned with water before curing.
Easy One-Part Application
Ready-to-use formulation requires no mixing and can be applied using a standard caulking gun.
Strong Adhesion
Bonds effectively to concrete, gypsum board, metals, wood, cable jackets, and various plastic materials, including CPVC.
Sag-Resistant Formula
Suitable for vertical, horizontal, and overhead applications.
Paintable Finish
Can be painted after curing to blend with surrounding surfaces.
Low VOC & Halogen-Free
Environmentally responsible formulation that supports green building requirements.

Frequently asked questions
Here are some common questions about
3M Fire Barrier IC WB+ Sealant
3M™ Fire Barrier Sealant IC 15WB+ is a one-part, latex-based, intumescent firestop sealant designed to seal penetrations and openings in fire-rated walls, floors, floor/ceiling assemblies, and construction joints.
When installed as part of tested and listed firestop systems, IC 15WB+ provides up to 3 hours of fire protection and helps prevent the spread of fire, smoke, and noxious gases.
It is suitable for a variety of through-penetration applications, including metallic and plastic pipes, CPVC pipes, conduits, power and communication cables, cable trays, busways, HVAC ducts, insulated pipes, blank openings, and static construction joints.
Yes. The sealant is designed for mechanical, electrical, and plumbing applications where service penetrations pass through fire-rated assemblies.
Yes. 3M specifies adhesion to plastic, including CPVC, making it suitable for approved firestop systems involving CPVC piping.
Yes. The sealant also acts as a barrier to airborne sound transmission and has an STC rating of 54 when tested in an STC 54-rated wall assembly.
Yes. It is a ready-to-use, gun-grade sealant that requires no mixing and can be applied using conventional caulking equipment.
Yes. The sealant is paintable after curing, allowing it to blend with surrounding surfaces where required.
Yes. It is designed to be re-enterable and repairable, which can be useful for future maintenance or modifications to service penetrations.
The opening and penetrating items should be cleaned to promote proper adhesion. Surfaces should be dry and frost-free before installation, and the applicable tested firestop system should be followed for backing material and sealant depth.
