Self-Healing Paint and Varnish Polymer Coatings

Resumo

The literature, patent, and authors’ data on procedures for preparing self-healing polymer paint and varnish coatings are summarized. “External” and “internal” routes of preparing such coatings, in particular, microencapsulation technologies and procedures based on specific rheological properties of polymers, are analyzed in detail. It is concluded that the efficiency of the encapsulation method for preparing coatings is low. Prospects for using polyurethane and thermoplastic film-forming agents for preparing self-healing polymer paint and varnish coatings are demonstrated.
