Барьерные свойства покрытий оценивали по характеру частотных зависимостей емкости и сопротивления окрашенных металлических пластин при контакте с 3%-ным водным раствором хлорида натрия, а также по величине смещения потенциала разомкнутой цепи с окрашенным электродом в сравнении с неокрашенным. Экспериментально установлено, что большее содержание гель-фракции характерно для покрытий, сформированных из низковязких пленкообразующих составов. Показано, что физико-механические и защитные свойства эпоксидных покрытий зависят от содержания функциональных групп в эпоксидной смоле и природы аминного отвердителя. Обнаружено, что для получения покрытий с лучшими свойствами предпочтительнее использовать аминные отвердители, которые характеризуются невысоким содержанием аминных групп и сниженной долей вторичных аминогрупп. Выявлена взаимосвязь между защитными свойствами покрытий и величинами водопоглощения. Предложено использовать изучение особенностей водопоглощения покрытий как простой экспресс-метод оценки их барьерных свойств. Рассмотрены технологические аспекты применения исследуемых составов при производстве антикоррозионных лакокрасочных материалов и показаны преимущества применения низковязких эпоксидных пленкообразующих систем, не содержащих инертных растворителей.</p></abstract><trans-abstract xml:lang="en"><p>The article examines the physicomechanical and barrier properties of non-pigmented epoxy coatings formed from various film-forming systems based on epoxy resins and amine hardeners. The barrier properties of the coatings were evaluated by the nature of the frequency dependencies of the capacitance and resistance of the painted metal plates in contact with a 3 % aqueous solution of sodium chloride, and also by the magnitude of the displacement of the open circuit potential of the painted electrode compared to unpainted. It was experimentally established that a higher content of gel fraction is observed for coatings formed from low-viscosity film-forming compositions. It is shown that the physicomechanical and protective properties of epoxy coatings depend on the content of the functional groups in the epoxy resin and the nature of the amine hardener. It was found that to obtain coatings with better properties, it is preferable to use amine hardeners characterized by a low content of amine groups and a reduced proportion of secondary amino groups. A relationship was found between the protective properties of coatings and their water absorption. It is proposed to use the characteristics of water absorption of coatings as a simple method for assessing their barrier properties. The technological aspects of the use of the studied film-forming systems in the production of anticorrosive paints are considered. The advantages of using low viscosity epoxy film-forming systems without inert solvents are shown. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>эпоксидная смола</kwd><kwd>аминный отвердитель</kwd><kwd>барьерные свойства</kwd><kwd>емкость покрытия</kwd><kwd>сопротивление покрытия</kwd><kwd>потенциал разомкнутой цепи</kwd><kwd>водопоглощение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>epoxy resin</kwd><kwd>amine hardener</kwd><kwd>barrier properties</kwd><kwd>coating capacity</kwd><kwd>coating resistance</kwd><kwd>open circuit potential</kwd><kwd>water absorption</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Розенфельд, И.
