Single component fire rated sealant and is a noncombustible filler caulking used for fire blocking applications in the annular space around wires, pipes, ducts, vents, cable lines and other penetrations to the building envelope. It is a non-slumping sealant that sets to form a hard surface. Can be applied to any gap or penetration where the specification is noncombustible and/or ASTM-E136 rated.
