Chemical formula: NH4H2PO4

Monoammonium phosphate is a perfect antipyren. This powdery substance is equally effective in extinguishing fires of solid, liquid and gaseous materials (classes of fires A, B and C). Temperature increase, caused by fire, turns this fire-retarding agent into a fusible vitreous substance, which covers hard surfaces by a fire-retarding layer, therefore it can be used to fight both fires, caused by combustion of regular combustible materials, such as wood or paper, and fires that involve combustion of flammable oil products, gas and electrical equipment.
The absence of insoluble impurities provides complete solution of monoammonium phosphate and improves absorption in materials such as fabric, plywood or wood, to achieve high fire resistance of-impregnated materials.
