Australia’s first certified flame-retardant polyurea coating
The economic impact of corrosion is often exacerbated in harsh climatic environments and in workplaces with heavy traffic wear from operation of large vehicles and equipment. Excessive moisture, heat and abrasion can accelerate the deterioration of machinery, vehicles and assets. Applying a protective surface coating is one way of minimising or reducing the effect. One coating material for harsh conditions—including those in a combat zone—supplied by Rhino Linings Australia (RLA) is Rhino Extreme 11-50 FR. While the material has been available for several years, it was only late in 2016 that the fire resistant nature of the product received certification. RLA’s Technical Manager, Robert Idzes, said “The formal certification of Rhino Extreme 11-50 FR has opened up a range of new opportunities for industrial and commercial applications of the product.” The spray-applied pure polyurea is suitable for any application, such as a fuel bund—secondary containment area—that requires a fire resistant surface. Historically, bunds have been constructed of concrete or brick, but in recent years have been coated with a spray-applied pure polyurea or welded plastic liner to prevent leaks. Fire is a potential hazard if a leak does occur, especially where fuel, sodium hydroxide, sulphuric acid and other highly flammable materials are stored. The flame resistant properties of Rhino Extreme 11-50 FR significantly reduces the burn rate allowing safety officers and staff time to extinguish the flames before major damage is caused to the liner or catastrophic failure occurs. “The Rhino Extreme 11-50 FR is the latest Flame Retardant product to meet US Federal Aviation Regulation 25 (FAR 25) Flammability testing for aircraft,” said Denis Baker, Special Projects Engineer at RLA. “In addition, it also meets UL 94, which is another high standard at the moment for coatings.” The FAR 25.853 tests the self-extinguishing performance of materials under fire conditions.
