K-FLEX K-FIRE SEALANT M

K-FLEX K-FIRE SEALANT M is a single-component, water-based intumescent sealant for construction joints and service penetrations. It cures to an elastomeric seal suited to applications where dynamic movement is expected. In a fire, the sealant restricts the spread of flames, smoke, hot gases and water through joint openings and penetrations. A combination of biocides protects the product against mould growth in both its wet and cured states.
