The Effect of Organosilanes on Protective Properties of Polymer Coatings for Underground Pipelines. Inhibition of Cathodic Peeling-off of Polymer Coatings from Metal

摘要

Protective properties of polymer coatings are mainly determined by their adhesion properties. Organosilanes represent the most commonly applied adhesion promoters; they are also capable of decelerating corrosion processes. In this study, the possibility of applying organosilanes in the function of inhibitors of cathodic peeling-off of polymer coatings has been investigated. It has been established that the introduction of vinyl silane to the coating results in the inhibition of cathodic peeling-off due to higher compatibility of vinyl with the components of the bitumen-polymer coating.
