Tried and Tested Fire Protection
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. 3M 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.

High-performance intumescent silicone achieves the benefits of a firestop and watertight seal

Fire Barrier Features
3M™ Fire Barrier Water Tight Sealant 3000 WT acts as an acoustic barrier by minimizing noise transfer (STC-Rating of 53 when tested in a STC 54-rated wall assembly). In addition, the high-solids formula produces limited shrinkage. This halogen-free sealant is sag-resistant and has an excellent caulk rate (applied with conventional caulking equipment). It dries to the touch in 30 — 60 minutes and can be painted. In addition, this sealant has been engineered to be re-enterable and repairable.
