Abstract

In this article influence of silicate fillers on operational properties of coatings, based on protective polymeric pastes VP-1 and VZP-1 with the lowered content of strontium chromate is studied. It is shown that microwollastonite introduction positively affects the adhesive durability, hardness and water absorption of the received coatings. It is established that partial replacement strontium chromate on microwollastonite as a part of VP-1 paste does not lead to decrease in protective properties of coatings, and in case of VZP-1 paste - allows to increase protective properties of coatings.
