Nardeli, Jessica V.; Fugivara, Cecilio S.; Taryba, Maryna; Montemor, M. F.; Benedetti, Assis V. published the artcile< Self-healing ability based on hydrogen bonds in organic coatings for corrosion protection of AA1200>, Formula: C19H34O2, the main research area is aluminum alloy corrosion resistant coating polyurethane microstructure.
Biobased polyurethane coatings derived from vegetable oils, with 2 different compositions, were prepared and applied on the AA1200 aluminum alloy to confer corrosion protection. The influence of the ratio between the polyester (flexible segment) and the prepolymer (rigid segment) was investigated. IR spectroscopy studies evidenced the difference between the areas of the bands (-NH) and optical and SEM evidenced the morphol. features of the coating surface before and after immersion in aggressive medium. The barrier properties and anti-corrosion performance of the coatings were evaluated by electrochem. impedance spectroscopy and the results revealed an increase of impedance over the immersion time. Localized corrosion studies confirmed the self-healing effect in coatings formulated with the highest content of polyester.
Corrosion Science published new progress about Anticorrosive coating materials. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Formula: C19H34O2.
