14 Investigation of the influence of certain functional additives on the properties of water-dispersion coating materials. Part 2 — Elizova O. S., Kolesnikov E. A., Candidate of Chem. Sci., Assoc. Prof. Nesterova A. G., Bazueva A. S., Pahomova O. M.
ABSTRACT. The investigation of the effects of coalescents and plasticizers of different chemical
natures on the properties of a water-dispersion acrylic floor enamel has been continued. The previous
publication examined the rheological properties of the formulations, their freeze–thaw resistance, andthe blocking resistance of the coatings. The present study investigates the properties of the resulting coatings, including gloss, hardness, abrasion resistance, and resistance to static water exposure. It has been demonstrated that the effects of the additives depend not only on their individual chemical nature but also on the combination of components. The results confirm the need for a comprehensive approach to the selection of functional additives, taking into account the overall set of technological and performance characteristics.
KEYWORDS: water-dispersion coating materials, acrylic floor enamel, coalescents, plasticizers.

32 Testing of an antifouling paint for underwater application on the floating nuclear thermal power plant «Akademik Lomonosov» — Ivanova A. M., Doctor of Tech. Sci. Drinberg A. S., Candidate of Ped. Sci. Danilova T. V., Aleksandrova A. Yu., Candidate of Chem. Sci. Didkovsky N. G.
ABSTRACT. A technology for producing antifouling materials designed for underwater application, ensuring the protection of underwater structures against biofouling in highly oxygenated marine environments has been developed. The underwater application technology was validated through actual diving operations. Betulin-based natural biocides, which have a minimal impact on marine flora and fauna, were utilized. The material is formulated using domestically sourced components. Field tests of thedeveloped materials on the underwater hull of floating nuclear power plant «Akademik Lomonosov» and on berthing structures in the town of Pevek were conducted.
KEYWORDS: biofouling, antifouling coatings, betulin, nuclear power plant, water displacement, oxygen
concentration in water.
46 Investigation of marble-like pattern formation in protective and decorative epoxy coatings on mineral substrates — Surnacheva M. M., Cand. Tech. Sci., Assoc. Prof. Fedyakova N. V.
ABSTRACT. Coating materials have been developed to produce decorative coating systems with a marblelike effect on mineral substrates. The film-forming component is a solution of a medium-molecular-weight epoxy resin in an organic solvent, with the addition of titanium dioxide and carbon black as pigments and fumed silica (Aerosil) as a filler. The interactions between pigments of different chemical nature, the influence of Aerosil as a functional additive, and the effect of coating thickness on pattern formation were investigated. The coating material used as the base layer of the system is intended for application to mineral substrates, such as concrete and glass, by pouring, flow coating, or dipping. The decorative effect is achieved by manually applying contrasting marble-like veins onto a continuous, uncured coating layer, resulting in a unique decorative pattern.
KEYWORDS: decorative solvent-based epoxy coating materials, marble, mineral substrates.

60 Raw components for UV-, LED- and EB-curable paints and varnishes used for painting of metal surfaces. Part 4: Adhesion promoters — Doctor of Tech. Sci. Nistratov A. V., Hua Chun, Yang Pengfei, Candidate of Chem. Sci. XIA Zhiyu Wilson, Nistratova O. V.
ABSTRACT. The summary overview of the range of adhesion promoters with their characteristics available
on the international market, potentially suitable for the manufacture of UV, LED and EB paint and varnish
materials for painting rolled and sheet metals, metal products, is presented.
KEYWORDS: paint and varnish materials, polymer coatings, adhesion promoters, metal surfaces.

24 Influence of the nature of leveling additives on UV-cured polyurethane varnish — Sozinova E. A., Burobin N. K.
ABSTRACT. This work investigated the influence of the nature of leveling additives and their concentration on the wettability and flowability of a material on a PVC substrate when added to a UV-curable polyurethane varnish. Wetting and flowability of the varnishes were determined by measuring the contact angle, material viscosity, and a special leveling test. The results of the study revealed the best chemical nature of the additive and its optimal concentration relative to the UV-curable polyurethane varnish.
KEYWORDS: leveling additives, wettability, spreading, surface tension, polyurethane varnish, coating defects.
