Thermocoat WI is a low odour, water-based coating, making it user and environmentally friendly. Thermoguard Flame Retardant Topcoats are 2010 compliant and safe to use in accordance with manufacturer’s instructions.
The heat of a fire triggers a catalytic reaction, causing the expansion of an insulating char layer up to 50 times the paint thickness. This layer keeps the steel below its critical temperature, thus maintaining the structural integrity of the building.
