Hempafire Extreme 550 is a two component epoxy solvent-free, chemically curing intumescent coating for passive fire protection of structural steel against cellulosic fires.
It is optimized from R30 to R120 fire durations and for in-shop applications. Fire protection at R180 and R240 may be possible depending on the project.
On-site applications may be possible depending on the equipment and set up.
As intumescent fire protection for structural steel in interior and exterior service conditions, up to Type X (EAD350402-00-1106 / EN 16623) and C5 conditions (ISO 12944-2). Suitable for I section beams, H columns, hollow sections and cellular beams. As a repair and touch-up coating for damaged areas of Hempafire Extreme 550.
Features
– Very competitive thicknesses resulting in reduced paint consumption and less coats to apply.
– Wide coverage of protectable Hp/A, allowing the use of light steel sections for higher fire ratings.
– Fire protection up to 4 hours. Optimized for the range of R30 toR120.
– Excellent durability towards mechanical damages, chemical resistance and weather exposure.
– Weather resistant and up to C5 conditions without topcoat. Topcoat only needed for aesthetic purposes.
– Smooth surface and compatible with a wide range of topcoats, allowing the desired Aesthetic finish of the steel.
– Reduced application costs and Fast process time, combining high DFT/coat with a reduced total PFP thicknesses to apply. Protection achieved in less coats.
– One product for most common steel sections to reduce complexity in application and specification.
– It has been approved and 3rd party certified according to EN13381- 8 and BS 476-21. It has ETA with CE mark and ApplusFire approvals.
– Can be applied up to 3-5 mm [118-196 mils] dry film thickness per coat (depending on the set up), thus providing the required protection in less coats.
– Optimized to maximize throughput and DFT/coat with plural feed application equipment. Application with single leg equipment also possible for touch ups / small areas.
– Solvent free / 100% solids, product has very low VOC. Environmental Product Declaration with third-party certification is ongoing (Type III EPD, acc. to ISO 14025, EN 15804). Product can contribute to EPD credits for LEED and BREEAM projects.
– Complies with EU Directive 2004/42/EC, The Paints Directive on the limitation of volatile organic compounds: subcategory i.
Certificates / Approvals
