Evostik fire rate foam filler is a modified one component polyurethane foam for the filling/sealing of joints & gaps requiring fire resistant properties. The foam expands rapidly after dispensing & quickly cures to a fine honeycomb structured foam by reacting with atmospheric moisture. It has excellent thermal & acoustic insulation properties & forms a strong bond to most construction materials. The propellant used has no ozone depleting potential. The product is supplied in pressurised aerosol canisters that forms an airtight seal to prevent transmission of smoke. Achieves 4-hours fire rating. Tested to BS476: Part 20.
Size: 700ml.
