NEWS ARTICLE ARCHIVES3M™ Fire Barrier IC 15WB+ Sealant from SignetThe 3M Fire Barrier IC 15WB+ Sealant is a latex sealant designed for use as a one-part fire, smoke, noxious gas and water resistant sealant. In addition, the unique intumescent property of this material (expands when heated) means that as the combustible cable insulation is consumed by fire, the sealant expands to maintain the penetration seal. IC 15WB+ Sealant can be installed with a standard or bulk 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, plastic and cable jacketing. No mixing is required. Tool within 5 minutes of application, if required. IC 15WB+ Sealant provides Fire Resistance Ratings of up to 2 hours. Product Features
