Metacaulk MC-150 Firestop Sealant

Metacaulk MC-150+  Firestop Sealant

Metacaulk MC 150+ is one component, general purpose fire-rated sealant and smoke seal for construction joints and through-penetrations. It prevents the spread of flames, smoke, and gas through penetration openings. Metacaulk® MC 150+ is a water-based, non-sag caulking grade sealant that is easy to apply as well as to retrofit. It cures to an elastomeric seal that is suitable where dynamic movement is expected in the event of a fire. Metacaulk® MC 150+ will prevent the spread of flames, smoke, hot gases and water through joint openings and through-penetrations.

Metacaulk® MC 150+ is applied with a conventional caulking gun, bulk loading gun or can be troweled or pumped directly from the pail.

Metacaulk MC 150+ systems are rated for up to 4 hours in accordance with ASTM E814 (UP1479) and ASTM E1966 (UL 2079) test standards.
