ANTICORROSION COATING COMPOSITION WITH AQUEOUS DISPERSION CONTAINING ORGANIC TITANATE Russian patent published in 2010 - IPC C09D183/04 C09D5/10 C09D5/08 

FIELD: chemistry.

SUBSTANCE: invention relates to an anticorrosion coating composition for metal components based on metal particles in an aqueous dispersion which is based on metal particles in an aqueous dispersion which contains 0.3-24 % organic titanate, 10-40% metal particles or mixture of metal particles, 1-25% silane based binder, and water - the remaining percentage up to 100%, provided that the sum of the percentage of the organic titanate and silane based binder is between 5 and 25%. The invention also relates to an anticorrosion coating for metal components made from the disclosed coating composition, as well a metal substrate onto which the anticorrosion coating is applied through sputtering, drainage-impregnation or centrifugation-impregnation, where the coating layer is then thermally treated, preferably at temperature between 180°C and 350°C for 10-60 minutes by supplying heat through convection or radiation, or for a period of time between 30 second and 5 minutes through electromagnetic induction. The invention also relates to an aqueous composition of C₁-C₈ tetraalkyl titanate for preparing a composition for coating a metal substrate in an aqueous dispersion obtained from a water-soluble organic solvent, silane-containing binder which has in its structure at least one functional group which can be hydrolysed to a hydroxyl group and water, as well as to use in preliminary processing of adhesives or coatings, for subsequent processing as a metal particle based sealant when passivating substrates based on steel, zinc, aluminium or steel having a zinc based coating, or in an additive for improving adhesion of coatings or adhesives in an aqueous phase.

EFFECT: design of a method of obtaining an efficient anticorrosion coating.
