FP100 is a high intumescent retardant coating that swells as a result of heat exposure or flame, converting combustible gases and tars to non-combustible carbon char causing the surface to bubble-up and creating a thermal barrier between the fire and the treated material. The carbon char is a poor conductor of heat, protecting the substrate from being consumed by the fire.
