FR CROS 480 Ammonium Polyphosphate Budenheim Flame retardant / Fire retardant >> Phosphorus based Coatings >> Solventborne Flame retardant agent Long chain ammonium polyphosphate Excellent catalytic effect in the dehydration of C-OH groups Easily dispersible good storgae stability Neither toxic nor corrosive Does not produce toxic combustion gases FR CROS 480 is a long chain ammonium polyphosphate phase I halogen free, fine white powder, insoluble in organic solvents. Therefore is used as a catalyst, for solvent based intumescent coatings. Under the impact of heat, FR CROS 480 decomposes under emission of non combustible gases which by forming a blaketing gas layer prevent the access of oxygen to the substrate. The residual acidic polyphosphates act as catalyst for the intumescent reaction by dehydration of carbon rich material. Non-toxic, non-corrosive, halogen free ammonium polyphosphate flame retardant agent. Used in solvent based coatings. Possesses good storage stability. Decomposes under the impact of heat. Induces emission of non combustible gases that are forming a blanketing gas layer and prevent the access of oxygen to the substrate. The residual acidic polyphosphates act as catalyst for the intumescent reaction by dehydration of carbon rich material. Does not produce toxic combustion gases.
