    摘要: Intumescent flame-retardant coating composition consisting substantially of a film-forming agent, an ammonium polyphosphate, one or more substances which are carbonizable under the action of heat, a dispersant, and optionally a filler. The coating composition additionally contains an ammonium polyphosphate activator weighing 0.5 to 50% of the weight of ammonium polyphosphate. The activator is constituted by at least one salt which contains water of crystallization which is liberated upon the composition being heated to about 35.degree. C.
