FIELD: polymer materials as corrosion protectors. SUBSTANCE: invention relates to epoxide resin-based compositions, which can be used for protection of materials and objects, preferably metallic, against effects produced by corrosive media including effects of sea water and/or mist with elevated concentration salt ions, as well as against solar radiation. Epoxide resin-based composition includes anticorrosive component containing liquid product from solid anthracites pyrolysis and additionally hexamethylenetetramine. For instance, liquid coal pyrolysis product can be used constituting azeotrope mixture consisting of paraffin-olefin compounds, monocyclic aromatic compounds, polycyclic aromatic compounds, neutral oxygen- containing compounds, and carboxylic acids. This product has freezing temperature no higher than -10 C, density at 20 C not higher than 1.06 g/cu.cm, and apparent viscosity at 50 C not higher than 1.3 s. Said product is preliminarily mixed with hexamethylenetetramine and resulting mixture is subjected to isothermal ageing at 100 +/- 5 C until gas formation ceased. To anticorrosive component, epoxide resin is added at 20 +/- 5 C. EFFECT: enhanced anticorrosive efficiency. 4 cl, 3 ex
