    Leaf extracts as green substitute to toxic zinc chromate and zinc phosphate additives in Polyurethane primers for corrosion inhibition of steel
    (Akadémiai Kiadó, 2021-10-13) Sodiya, Ezekiel Folorunso; Dawodu, Folasegun Anthony; nem
    Corrosion inhibition of steel by Polyurethane Extract-primer (PEP) containing plant leaf extracts was compared with Polyurethane Conventional primer (PCP) containing zinc phosphate and zinc chromate as inhibitors. The primers were investigated using gasometric technique in 5 °C steps of temperature increase from 25 to 50 °C in 1.0 M HCl as corrodent. The PEP of 34.24 percent actives compared with PCP of 56.35 percent actives gave the same inhibition efficiencies of 82.4%. Extract primers of low percent active concentration were more effective and less expensive than that of conventional primers.
