Description

The 3M FIRE BARRIER CAULK IC 15WB+ is a 10.1 oz cartridge of firestop sealant designed to help minimize sound transfer. This water-based and paintable sealant offers exceptional adhesion for long-term performance and can be applied with conventional caulking equipment. Its sag-resistant properties ensure clean application, and the sealant is re-enterable and repairable.

The IC 15WB+ firestop sealant has been tested for static construction joint systems and through-penetration applications for up to 3 hours in accordance with ASTM E 814 (UL 1479) and CAN/ULC S115. It features a halogen-free formula and is compatible with CPVC piping.
