Впервые с помощью экспресс-метода определена стойкость порошковых полиэфирных лакокрасочных покрытий. Метод основан на эмпирической экспоненциальной зависимости стойкости покрытия от энергии активации термоокислительной деструкции пленкообразующего. Сделана количественная оценка влияния ключевых разрушающих факторов на стойкость покрытий. Экспресс-метод заметно сокращает время для сертификации порошковых красок по такому фактору как "стойкость" и их промышленное применение в качестве покрытий для металла, бетона, асбестовых плит.

For the first time ever durability of powder polyester paint coatings was determined by an express method. The method is based on empirical exponential dependence of coating durability on activation energy of thermal-oxidative degradation of paint filming agent. Quantitative evaluation of the impact of key destructive factors on coatings durability was made. The express method noticeably shortens time for certification of powder paints by such factor as “durability”, and their manufacturing application in obtaining coatings for metal, concrete, asbestos boards.
