3M™ Fire Barrier IC 15WB Sealant

• Water Base: Easy clean up, no special handling, routine disposal 
• Intumescent: Expands when heated to maintain seal around items consumed by fire. 
• Endothermic: Absorbs heat energy, releases chemically bound water
• Thixotropic: Will not sag or run in overhead or vertical applications

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.
