FLAMEfixx dFx® is impregnated with dFx technology. This patented, industry-leading technology combines a globally approved, durable (d) wood preservative and a proprietary fire-retardant (Fx) into a single working solution. Once the timber is impregnated with the dFx® solution, the active ingredients are fixed in the wood for the life span of the timber. The fire-retardant component of FLAMEfixx dFx® is based on inorganic natural ingredients that don't contain hydrocarbon or carbon. This results in low smoke generation levels during combustion in a bush fire, wildfire or fire situation.
