Thermoguard Thermocoat WI is the ultimate water-based intumescent paint system providing essential fire protection to structural steel and cast iron. This high-performance intumescent coating is engineered to offer up to 90 minutes of fire resistance to load-bearing elements of structures, ensuring safety and compliance. When exposed to heat, the paint undergoes a chemical reaction, causing the expansion of an insulating char layer that protects the steel from reaching critical failure temperatures.
