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.
