The article presents the results of experiments to study the effects of a mixture of phosphoric acid with hydroxyethylidene diphosphonic acid on rust and recrement. It has been found that it dissolves both of these iron corrosion products. Based on the results obtained, a primer converter of corrosion products has been developed, the film-forming agent of which is plasticized polyvinyl acetate dispersion.

The work proposed a novel approach for creating solvent-based polymer paints from powder coating waste. Polymer paints were created by dissolving powder coating waste with a complex solvent and adding a crosslinking agent — aliphatic polyisocyanate. The final product has been tested for quality control.

Underwater fullscale tests of the special underwater antifouling Exidis enamel out in the Pechersk Sea were carried. The enamel does not contain organic solvents and cuprous oxide. The enamel has a water displacement effect, antifouling and anti-corrosion properties. The composition contains environmentally valuable biocides that do not contain metal ions. Exidis enamel can be used as an antifouling material in the conditions of the Far North, Arctic and Antarctic has been established.

Various systems of flame retardant coatings are used to protect metal structures of platforms and rack structures of oil and gas facilities from low (in case of cryogenic liquids spill) and high temperatures (in case of possible development of hydrocarbon fire regime). The article presents the results of tests of fireproof coatings on epoxy binder after modeling of liquefied hydrocarbons spill and subsequent development of hydrocarbon fire regime. Experimental data for epoxy coatings under a standard fire regime are also presented. By solving the inverse heat conduction problem using finite element modeling it was possible to determine the thermophysical properties of the formed foam coke at the end of fire tests of metal structures with epoxy coatings. The average thickness of the epoxy coating to achieve fire protection efficiency of 120 min and the consumption of the coating for hydrocarbon fire mode compared to the consumption in the standard mode were determined. Nomograms of dependence of the time of reaching the critical temperature on the volume coefficient at standard and hydrocarbon fire modes, at different thickness of the dry layer of epoxy coating are constructed.
