This article examines the scientific and technological basis of anticorrosive coatings formulated with nano-sized particles, the principal classes of nanofillers used in coating systems, their interaction with polymer matrices, and the key stages of coating formation. Corrosion remains one of the main causes of service-life reduction in metal structures, pipelines, transport equipment, agricultural machinery, and chemical apparatus. Conventional coatings often fail under moisture, chloride exposure, ultraviolet radiation, and mechanical damage. The incorporation of nano-sized fillers into epoxy, polyurethane, and sol-gel matrices can improve coating density, barrier behavior, adhesion, resistance to microcracking, and long-term protective performance. The paper discusses the roles of SiO2, ZnO, TiO2, Al2O3, graphene oxide, nanoclays, and related nanofillers. Rather than inventing laboratory data, the study follows an analytical IMRAD structure based on literature synthesis, comparison of composition–property relationships, and stage-by-stage modeling of the technological route. The analysis shows that when nanoparticle loading and dispersion are properly controlled, coating resistance to corrosive media, mechanical integrity, and operational durability improve substantially.
