PHYSICO CHEMICAL RESEARCH
13 Colloidal-chemical properties of pigmented water dispersions of methylphenylpolysiloxane resin and paint materials based on them — Doctor of Chemistry, Prof. Koshevar V. D., Shkadretsova V. G.

DOI 10.67632/0130-9013-2026-7/8-13-22
ABSTRACT. This study investigates the influence of the chemical nature, concentration, particle shape, pH of the dispersion medium, and various functional additives on the sedimentation and aggregative stability of mixed aqueous dispersions of methylphenylpolysiloxane resin and mineral powders (titanium dioxide, mica). The structural-rheological properties of such concentrated dispersed systems are examined. The experimental data obtained and the identified patterns form the basis for the development of a new water-dispersible heatresistant paint formulation.
KEYWORDS: methylphenylpolysiloxane latex, mixed dispersions of water-dispersible polymer, mica and titanium dioxide, anionic and non-ionic surfactants, dispersants, coalescents, structuring additives, rheological curves.

29 Study of resistance to petroleum products of paint and varnish compositions based on epoxy resins — Kozlova E. V., Fomichev A. P., Kirpal Yu. G., Malyavina Ya. M., Candidate of Tech. Sci. Silaeva A. A.

DOI 10.67632/0130-9013-2026-7/8-29-36
ABSTRACT. This paper examines the petroleum resistance of epoxy resin-based paint and varnish compositions for the production of coatings designed to protect the interior surfaces of pipelines operating in modern oil transportation environments. Optimal components for the production of a high-solid primer-enamel coating were selected. The properties of varnish compositions based on a phenalkamine hardener and an aminosilane hardener were studied, as well as their combination with active diluents of various functionalities — C12–14 alkyl glycidyl ether, alkylphenol monoglycidyl ether, and 1,4-butanediol diglycidyl ether—were also examined. The physical and mechanical properties of the resulting primer-enamel coating were also studied. The effect of fluoroplastic on increasing the coating's hydrophobicity was also examined.
KEYWORDS: epoxy oligomer, reactive diluent, epoxy hardeners, adhesion, impact strength, heat aging, chemical resistance, hydrophobicity.

37 Application of protective anti-corrosion coatings to large-diameter pipes — Candidate of Tech. Sci., Associate Professor Khrenov S. I., Senior lecturer Turchaninova Yu. S., Senior lecturer Melnikov P. V., Panushkin A. V.

DOI 10.67632/0130-9013-2026-7/8-37-41
ABSTRACT. A technological process and equipment for producing anti-corrosion coatings on large-diameter pipes have been developed. This process includes shot blasting and dust removal, induction heating, application of powder material, subsequent polymerization, and cooling of the finished coating. Approaches to developin equipment for a conveyor line for insulating large-diameter pipes have been proposed.
KEYWORDS: еlectrostatic spraying, equipment for producing anti-corrosion coatings, tubular products, coating application, conveyor line, protective coatings.

METHODS OF TESTING
42 Specific volume resistance as a monitor of the completeness of the curing process of organosilicate coatings — Krasilnikova L. N., Candidate Phys.-Mathem. Sci. Alekseev V. A., Dr. Chem. Sci. Prof. Shilova O. A.

DOI 10.67632/0130-9013-2026-7/8-42-48
ABSTRACT. The influence of both cold and hot curing modes on the specific volume resistance of coatings obtained from the organosilicate composition OS-51-03 and the KO-921 varnish was studied. Based on the obtained results, the possibility of using one of the parameters characterizing the electrophysical properties of coatings — specific volume resistance, as an indicator of the degree of curing of organosilicate coatings and the completion of this process is discussed.
KEYWORDS: organosilicate composition OS-51-03, KO-921 varnish, AGM-9 and MSN-7 hardeners, specific volume resistance, cold and hot curing, degree of curing.
