30 Effect of cellulose acetate butyrate molecular weight and acrylic binder type on the orientation of aluminum effect pigments — Postgraduate student Malyavina I. M., Bardina O. I., bachelor of the 4th year Moiseenkova Yu. V.
DOI 10.67632/130-9013-2026-9-30-36
ABSTRACT. This work is devoted to the study of the influence of the molecular weight of cellulose acetobutyrate (CAB) and the nature of the acrylic binder on the orientation of aluminum effect pigments in two-component polyurethane coatings. The results of the conducted studies show the need to select CABS based on the rheological response of a specific pigmented system, and a correlation has also been established between the rheological profile of the system and its decorative characteristics.
KEYWORDS: aluminum effect pigment, cellulose acetate butyrate, CAB, Silver Dollar, PVD, flop index, rheology,
acrylic polyol, particle orientation.

PROCESSING OF POLYMERS AND COMPOSITES
44 Аntistatic coatings for a wide range of applications using core-shell technology — Sumsky A. V., Candidate of Chem. Sci. Didkovsky N. G., Sokolov G. S., Doctor of Tech. Sci. Drinberg A. S.
DOI 10.67632/130-9013-2026-9-44-50
ABSTRACT. Requirements for antistatic coatings for various premises are formulated. The mechanisms of action of antistatic coatings are studied. The main types of conductive surfactants used to create antistatic coatings are considered. Methods for measuring surface and volume resistance of materials are presented.The development of a new generation of antistatic coatings using a polymer additive created using core-shell technology is described. It has been established that the introduction of 3–4% of the core-shell additive into a water-dispersed composition reduces surface resistance by more than half. It has been proven that the use of core-shell materials allows for a reduction in the content of conductive compounds in paint formulations and a wider range of coating colors.
KEYWORDS: static electricity, antistatic coatings, water-dispersed materials, specific surface resistance, specific
volume resistance, core-shell materials.

SAFETY
51 Development of a testing methodology for the determination of fire hazard indicators of paints and coatings using numerical simulation — Senior lecturer Grigoriev D. V., Senior lecturer Kovaleva S. A., Lyavin I. A.
DOI 10.67632/130-9013-2026-9-51-60
ABSTRACT. A two-stage testing methodology for the determination of fire hazard indicators of paints and coatings is proposed, targeting R&D specialists and technologists at paint manufacturers. The methodology integrates a preliminary computational-experimental Stage I — TGA/DSC analysis with metrological traceability, isoconversional pyrolysis kinetics, inverse model optimisation via PROPTI+FDS, and CFD simulation of a virtual cone calorimeter in FDS v.6 with V&V following NIST SP 1018 and MaCFP benchmarks — as a precursor to mandatory physical testing (Stage II). A four-class classification of paints by pyrolysis complexity, NAE metric with MaCFP Workshop 3 thresholds, LoC system, sensitivity index Si, and a formalised uncertainty budget (separating kinetic input data, model, and numerical solver contributions) are introduced. The methodology addresses the inapplicability of GOST 30244-94 to liquid paint formulations and may reduce physical testing by 40–60% during iterative formulation development.
KEYWORDS: paint and varnish materials, fire safety, numerical modeling of pyrolysis, FDS, cone calorimeter,
verification and validation, NAE, LoC, MaCFP, TGA, DSC, metrological traceability, measurement uncertainty.
