Synthesis and properties of morphologically different particles with the structure of zincite and periclase in organic coatings

Abstract

Purpose

The purpose of this paper is to synthesize MeO‐type pigments, focusing on the oxides containing zinc and magnesium.

Design/methodology/approach

Oxides ZnO and MgO were synthesized, their morphology was evaluated, and their impact on the physical properties of the paint film were assessed. A pigment of ZnO/core‐shell type also was synthesized. The physical‐chemical property of the synthesized pigments and the anticorrosion efficiencies of the paint films pigmented by them were determined. The binder used in the researched coatings was epoxy‐ester resin.

Findings

The shape of the particles was identified in the synthesized pigments. X‐ray diffraction analysis revealed the degree of precipitation and lattice parameters. All of the synthesized pigments had good anticorrosion efficiency in an epoxyester coating.

Practical implications

The synthesized pigments can be used conveniently in coatings protecting metal substrates against corrosion.

Originality/value

Of benefit is the fact that the synthesized pigments do not contain any environmentally harmful substances.
