Abstract

A method of promoting the adhesion between a coating based on at least one polymer and a substrate surface that can be made of different materials in which an adhesion promoter comprising at least one, optionally oligomeric, addition product having no terminal C═C double bonds and has hydrolyzable silane groups and other functional groups is included in the coating composition, included in a preliminary coating applied to the substrate surface prior to the actual coating, is applied between the coating and substrate surface, or any combination thereof.
