metacaulk® 835+ is a one component, fire-rated elastomeric neutral, moisture cure silicone sealant for use in through penetration firestops and construction joints. Available in caulk-grade and self-leveling. In the event of a fire, metacaulk® 835+ will prevent the spread of flames, smoke, gas and water through penetration openings. metacaulk® 835+ caulk-grade is a flexible, non-slumping sealant with excellent moisture resistance. For use in interior or exterior expansion and control joints and interior or exterior penetrations. Because metacaulk® 835+ is silicone based, it can be used in systems where dynamic movement is expected. metacaulk® 835+ is protected in a wet stage as well as in a dry stage against mold growth with a combination of biocides.
