Metacaulk 350i Intumescent Firestop Sealant

Metacaulk® 350i is an intumescent, water-based, non-sag caulking grade sealant that is easy to apply and is great for retrofits. It cures to an elastomeric seal that is suitable where dynamic movement is expected. In the event of a fire, Metacaulk® 350i will prevent the spread of flames, smoke, hot gases and water through joint openings and through-penetrations. Metacaulk® 350i systems are rated for 1, 2 and 3 hours in accordance with the ASTM E814 (UL 1479), UL 2079 and ULC-S115-95 test standards.
