3M™ Fire Barrier 2000 Silicone Sealant (Non-slump) is a ready-to-use, gun-grade, one-component silicone elastomer designed for firestop applications. It cures upon exposure to atmospheric humidity to form a flexible seal, supporting consistent performance in a range of installation conditions.

This fire barrier sealant is used to firestop openings and penetrations through floor slabs, walls, and other fire-rated building partitions and assemblies. When properly installed, 3M™ Fire Barrier Sealant helps control the spread of fire before, during, and after exposure to open flames.
  • Great for top-of-wall/head-of-wall joints
  • Superior adhesion
  • Provides up to a 4-hour fire-rating
  • Cures upon exposure to atmospheric humidity
  • Applied with conventional caulking gun
