Steelguard FM550 is a one component thin-film solvent borne intumescent coating designed for providing a fire protective coating to structural steelwork in an industrial environment.
Steelguard FM550 has been tested to national and international standards and can be used in dry, internal environments without the use of a protective topcoat. Steelguard FM550 is an excellent fire resistant product that provides up to 2 hours of protection from cellulosic fires and provides surface with 12 months of weather resistance, when a topcoat isn't used, providing the structure isn't immersed in water or exposed to high humidity.
Steelguard FM550 can be applied using airless spray for optimum performance and a brush should only be used for touch ups and small tricky areas. Steelguard FM550 should not be applied below 5 degrees or above 50 degrees Celsius, otherwise it may not adhere to the surface properly. With quick drying time FM550 is dry in just 30 minutes and be recoated after 6 hours in conditions of around 20 degrees Celsius.
Surface and Environment
Steelguard FM550 can be used of on-site or off-site application and when dry produces a high quality, white matt, protective coating that can be used internally or externally to ensure that structural steel has the utmost protection from the risk of fire.
