For timber substrates that require class 0 Spread of Flame or Euro class B.
Nu-Flame Clear Impregnation is a water based, ready to use solution that is absorbed into the surface of the substrate.
Nu-Flame Clear Impregnation is easy to apply, possessing high diffusion properties it quickly penetrates the surface of the substrate. It does not require a protective finishing coat and can be left natural or if specified over-coated. Left naturally, timber may darken slightly.
Nu-Flame Clear Impregnation has non-flammable properties which restrict ignition and the spread of flame. It will not wash out once dry, it is not converted into smoke when exposed to high temperatures, and carbon char is restricted to the immediate area. Materials treated with Nu-Flame Clear Impregnation when exposed to temperatures of up to 1700°C are subject to charcoal forming, restricting the spread of flame.Purchase
