Fire resistance. Italian paint is made of various binders, fillers, foaming materials and additives, among which fly ash is also used as filler. The fire prevention mechanism is mainly that the hydration products of silicate in coatings absorb heat, decompose when heated, consume heat during phase change, produce non-toxic inert gas, destroy the necessary conditions for combustion and form a foaming layer. Thereby having strong fire resistance and not generating toxic gas.
