Abstract

The structure and properties of urethane varnish coatings based on isocyanate-containing prepolymers are studied using the methods of atomic force microscopy, thermomechanical analysis, differential scanning calorimetry, and dynamic mechanical analysis. By the modification of isocyanate-containing prepolymers with dicyandiamide, the possibility of producing urethane varnish coatings having different supramolecular structure, high thermal and operational properties is shown.
