Fire Resistant is a single-component polyurethane foam in an aerosol canister. As the product is dispensed it produces a foam which reacting with the humidity in the air, increases in volume, gradually hardens and loses its initial tackiness. A grey, semi-rigid, waterproof and adhesive foam is produced. Its special formula provides the hardened foam with high resistance to fire. The hardened foam may be cut, holed, sanded, painted and plastered. It adheres firmly to wood, concrete, tile, asbestos cement, metal, glass and various plastics with the exception of polyethylene, Teflon and silicon. It also has high resistance to water, detergents, micro- organisms and chemical agents. Its uniform cellular structure and dimensional stability and the mechanical properties of the hardened foam make Fire Resistant ideal for gluing, securing, isolating, sealing and plugging when high resistance to fire is required. Using Fire Resistant, you can obtain joints with fire resistance up to REI 120, without the use of additional material such as rock wool on walls right down to a minimum thickness of 10 cm. The product is certified as EC 1 Plus by GEV in terms of very low emissions of volatile organic substances.
This has been proven in tests performed by CSI, Bollate (MI), an accredited testing agency authorised by the Civil Protection Directorate of the Italian Interior Ministry. CSI performed fire resistance tests in accordance with the standards EN 1366-4 and EN 1363-1. These tests showed that joints foamed with Fire Resistant as described in the table below prevent the passage of flames, fire and gas and guarantee thermal insulation for up to 120 minutes. The joints tested had the following geometries (see the Official Classification Test Reports No. CSI1760RF and No. CSI1761RF of 05/07/12). The wall was made with aerated, autoclaved concrete with a density of 500 kg/m³.

Fire Resistant is used for sealing linear joints in applications subject to fire regulations (EI classification).
Fire Resistant can also be used in applications where no specific fire resistance requirements covered by existing classifications are stipulated. In other words, it can be used in all those applications where a standard single-component polyurethane foam is required.
Fire Resistant complies with CEI 64-8, art. 511.1 having successfully passed the 850 °C Glow Wire Test as per CEI EN 60695-2-11 (certificate available on request). It can therefore also be used for fixing electrical conductors and junction boxes.
