Description
изоцианата и отверждают без дополнительного подогрева.isocyanate and cure without additional heating.
Использова 1ие предлагаемого способа позвол ет упростить технологию получени композиции. Введение карбоновых кислот и их производных в композицию дает возможность улзчшить совместимость полиэфиров с битумом и тем самым повысить физико-механические свойства. Исключение из композиции растворител снижает ее токсичность и пожароопасность.Using 1 of the proposed method allows to simplify the technology of the composition. The introduction of carboxylic acids and their derivatives into the composition makes it possible to improve the compatibility of polyesters with bitumen and thereby increase the physicomechanical properties. The exclusion from the composition of the solvent reduces its toxicity and fire hazard.
