Comparative Study of the Behavior of Ammonium Phosphate in Fireproofing Intumescent Formulations

A comparative study of the behavior of ammonium dihydrogen phosphate and partially substituted ammonium polyphosphates in fireproofing formulations based on organic solutions of polymers was made. Differences in the interaction of monomeric and polymeric acidic salts with the surface of a metal being protected were revealed.
