Intumescent coating : Hempafire Extreme 550

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.

Recommended use 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 to
R120.
- 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.
