Corrosion Resistant Paints for Automotive

Corrosion inhibitor for metal coatings that prevents paint falling off and extends the corrosion protection period. The inhibitor is a tertiary amine compound with a hydroxyethyl group. It is prepared by reacting an isocyanate with a primary amine and a secondary amine in the presence of water. The reaction forms a tertiary amine with a hydroxyethyl group as an intermediate, which is then used as the corrosion inhibitor. The inhibitor is added to the coating formulation to prevent metal corrosion when the coating is applied.

Mechanochemical synthesis of a composite inhibitory pigment for corrosion protection of metal structures in corrosive environments. The pigment is formed through a solid-state reaction between synthetic zeolite NaA and zinc dihydrogen phosphate in a planetary ball mill, resulting in the formation of a nanostructured zinc phosphate phase on the zeolite surface. This composite pigment, with a 1:1 zeolite to zinc dihydrogen phosphate ratio, exhibits enhanced solubility in corrosive environments compared to traditional zinc phosphate pigments, while maintaining sufficient inhibitory properties to prevent underfilm corrosion. The composite is then combined with epoxy resin and other additives to create a protective coating system.
