Metacaulk® 350i is a one-component general purpose fire rated sealant and smoke seal for construction joints and through-penetrations. Metacaulk® 350i is a water-based, extremely intumescent, non-sag caulking grade sealant 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 is easily applied with a conventional caulking gun, bulk loading gun or can be troweled or pumped from the pail.
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.
