What's special about this silicone sealant?

3M™ Fire Barrier 2000 Silicone Sealant (Non-slump) is a ready-to-use, gun-grade, one-component silicone elastomer. It cures upon exposure to atmospheric humidity to form a flexible seal. 3M™ Fire Barrier Sealant firestop openings and penetrations through floor slabs, walls and other fire-related building partitions and assemblies. 3M™ Fire Barrier Sealant, when installed properly, will control the spread of fire before, during and after exposure to open flames.

  • Unvented spaces where sealant is not exposed to atmospheric moisture
  • Wet or frost-coated surfaces
  • Areas that are continuously damp or immersed in water
  • “Yellow” brass (high zinc, 34 to 37 percent zinc)
