Evaluation of corrosion protection of carbon steel by anticorrosive paints

Purpose - The paper aims to evaluate the anti-corrosion performance of inorganic pigments included in paint systems based on plasticized-chlorinated rubber for carbon steel in different environmental conditions. Design/methodology/approach - Paint systems based on chlorinated rubber and inorganic pigments such as zinc chromate, zinc phosphate, red iron oxide and treated iron industry waste powder were prepared. Immersion in 3.5 percent salt solution, as well as outdoor exposure tests, were performed and the paint physico-mechanical properties were tested to evaluate the paints' anti corrosive performance. Findings - The concentration and the type of pigments included in the prepared paint systems control their anticorrosive performance. Originality/value - The paper demonstrates how pigment consisting of treated iron industry waste powder could be used in anticorrosion paints for carbon steel.
