Inhibited protective coatings based on polyurethane

  • L. М. Bilyi

We establish the synergism of inhibition of the corrosion processes in steel placed in weakly acid corrosive media by compositions of pigments based on zinc/iron phosphate and wollastonite. A mechanism of their protective action is proposed. The influence of filling of a polyurethane primer with a mixture of zinc/iron phosphate and wollastonite on its anticorrosion and physicomechanical characteristics is investigated. On the basis of the results of experimental investigations, we develop a new polyurethaneperchlorovinyl primer for protecting the problem sections of pipelines at the sites of earth–air transitions.
