This paper investigates the fire properties of a liquid organic component of an intumescent type of material for
protection from electromagnetic fields. The flammability group of the organic component of the protective composition
was determined depending on the thickness of the film. It is shown that an increase in the film thickness from 1 mm and
more even after 16 cycles of accelerated tests provides the first group of flammability. It was found that with a coating
thickness of 1 mm, the temperature of the flue gases slightly exceeds the critical value (260 °С) in the range of 86-106
sec and 255-266 sec, the weight loss is 5.2%, which makes it possible to classify the organic component of the protective
material as a flame retardant and non-flammable. The paper presents complete data on the fire dependence of the
considered water-dispersive binder with a complex of coke-forming agents. It was found that an organic binder of the
intumescent type with a film thickness of 1 mm, regardless of the test conditions, is characterized by the first group of
flammability.
