K-FLEX K-FIRE SEALANT N

K-FLEX K-FIRE SEALANT N is a single-component, water-based, non-sag sealant for fire-rated construction joints and service penetrations. It provides fire, smoke and acoustic sealing and restricts the passage of flames, smoke, hot gases and water during a fire. The product can be applied with a conventional caulking gun, bulk-loading gun or trowel. Tested systems are rated for up to four hours in accordance with ASTM E814 and ASTM E1966, while biocides protect against mould growth in both wet and cured states.
