3M™ Fire Barrier IC 15WB Sealant
Expands in High Temperatures to Seal Out Smoke and Flames
|
What's special about this sealant?
3M™ Fire Barrier IC 15WB Sealant is a latex sealant designed for use as a one-part fire, smoke, noxious gas and water sealant. |
The unique intumescent property of this material (expands when heated) means that as the noncombustible pipe, cable or pipe insulation is consumed by fire, sealant expands to maintain the penetration seal.
- Halogen-free
- Fast dry: Tack-free in approximately 8 to 12 minutes @ 73°F (23°C)
- Paintable. Best results obtained after 72 hour cure
- Minimal shrinkage
- Yellow color
- Water seal: Seals against inadvertent water spills in the unexpanded state
- High sealant rate: 2000 g/min. with 1/4 in. (6 mm) nozzle
- Point contact allowed
- Continuous Operating Temperature not to exceed 120°F (48°C)
IC 15WB Sealant features superior adhesion strength, sealant rate and no-sag application with UL Classified fire protection systems plus a halogen-free formula.
3M™ Fire Barrier IC 15WB Sealant can be installed with a standard caulking gun, pneumatic pumping equipment or it can be easily applied with a putty knife or trowel.
Sealant bonds to gypsum wallboard, concrete, metals, wood and cable jacketing. No mixing is required. Tool within 5 minutes of application, if required.

If it's yellow and 3M, it's UL-tested

It's not safe to assume that because a firestop caulk is red, it has been UL-tested for your applications. 3M offers the yellow firestop caulk that has been UL-tested to ASTM E 814 for the most common applications.
3M Fire Barrier IC 15WB Caulk is an affordable firestop caulk that helps you stay on budget. Our distinctive yellow firestop caulk makes inspections easier. Plus, our fire barrier sealant provides protection around typical pipe and cable penetrations through fire-rated construction.
