3M™ Fire Barrier Water Tight Sealant 3000 WT: Product Data Sheet 

Ready-to-use, 3M™ Fire Barrier Water Tight Sealant 3000 WT is an intumescent, silicone elastomeric sealant. This gun-grade sealant cures upon exposure to the atmosphere 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. This sealant is water-tight to help prevent the intrusion of moisture. It is an ideal choice for CPVC piping. 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.

• Firestop tested up to 4 hours in accordance with ASTM E814 (UL 1479) and CAN/ULC-S114
• High-solids formula produces limited shrinkage
• Continuous seal remains pliable and allows for typical pipe movement
