Исследование влияния структуры аминных отвердителей на барьерные свойства эпоксидных систем

<jats:p>This paper presents the results of full-scale climatic tests of acrylic coatings in various colors, according to the international RAL color matching system (7016, 7024, 8017, 9003, 9005 — from the RAL Classic palette), designed to protect polyvinyl chloride products. The protective and decorative properties and weather resistance of dark-colored and white coatings were studied, and the aging of the material was assessed over 10 months of exposure in three climatic zones of Vietnam’s tropical climate temperate tropical, tropical monsoon, and subequatorial. The protective and decorative properties of the coatings were assessed both visually and by changes in optical characteristics — color and gloss. The results of full-scale tests demonstrated good weather resistance of the protective acrylic coatings in tropical conditions.</jats:p>
