Hempafire Optima 500 is a very low VOC, one-component waterborne acrylic thin film intumescent coating for passive fire protection of structural steel against cellulosic fires. It has been optimized for On-site applications at R120. Applications in shop and/or R180 may be possible depending on the project.
  • Features

    Developed to increase the efficiency of the entire PFP project, from initial specification through to final application. Increased productivity thanks to high DFT per coat and faster drying, thus providing the required fire protection in less coats, reduced application costs and faster process time. Tested and approved according to EN13381-8 for up to 120 minutes fire protection. It has ETA with 3rd party verified CE mark. It has BS-476 Assessment for up to 180 minutes fire protection with ApplusFire certificate. One product for most common section types to reduce the complexity in the application and design specification stages. Ease of application contributes to smooth surface and excellent aesthetic results of protected steel. Environmental Product Declaration with third-party certification available (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.
  • Recommended use
