Brosteel Ultra 60 is a thin-film waterborne intumescent coating designed to provide 30 and 60 minutes fire resistance on standard structural steel members in internal environments. Steelwork to be coated with Brosteel Ultra 60 must be primed with anti-corrosion primer suited to the intended environment of the building and applied to the manufacturer's specification with the exceptions that the dry film thickness does not exceed 100 microns and that thermoplastic, bitumen or chlorinated rubber coatings are not used. If the steel has been galvanised or coated with a zinc-rich primer, a suitable tie-coat should be applied. In a fire, the Intumescent base coat softens and expands to form a carbon foam layer, which insulates and protects the structure from intense heat.
