FIELD: chemistry.
SUBSTANCE: invention relates to aqueous compositions of intumescent coating. Composition contains a non-ionic surfactant with a hydrophilic-lipophilic balance (HLB) from 9 to 20 and an acid source. Cured coating deposited from the coating composition while heating in accordance with standard EN1363-1 on substrate of 1-foot H-beam from low-carbon steel W6x16 has coefficient of expansion of coke from 40 to 75.
EFFECT: higher fire-retardant efficiency of coating.
