This article explains how the process works. According to researchers at Al-Azhare university and Helwan university in Egypt, a considerable improvement in durability and the film performance of coatings can be achieved with a new raw material pre-cursor - m-phenylene dioxy diacetic acid (PDODA). This recently synthesised material can be used in the production of various alkyds and polyester-amide resins by partial substitution of phthalic anhydride.

Langues : Américain (ame) Index. décimale : 667.9 Revêtements et enduits Résumé : Metal complex pigments have been widely used for various applications such as pigments in coatings. This work presents the use of microwave technique (Green chemistry) for the synthesis of new copper(II), nickel(II), iron(III), and chromium(III) Schiff base complexes derived from metal salts and Schiff base ligand. Also, the microwave technique was used in the synthesis of Schiff base ligand which is derived from selected amine, namely methoxy-tolidine, and selected aldehyde, namely 2-hydroxynaphthaldehyde. The prepared ligand and metal complex pigments were characterized by elemental analysis, NMR, spectral UV–Vis, infrared, and thermal gravimetric analysis. The physical and mechanical properties and corrosion resistance of dry paint films were also examined. The obtained results revealed that the prepared metal complex pigments showed excellent mechanical and corrosion resistance.
