Metacaulk® MC-150+ Firestop Sealant is a 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.
MC-150+ Firestop Sealant is a water-based, non-sag caulking-grade sealant that is easy to apply and retrofit. It cures an elastomeric seal suitable where dynamic movement is expected in the event of a fire. MC 150+ Firestop Sealant will prevent the spread of flames, smoke, hot gases, and water through joint openings and penetrations.
Metacaulk® MC 150+ can be applied with a conventional caulking gun, bulk loading gun, or 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.
