METHOD OF PLATING METAL SHEET, PARTICULARLY ZINC SHEET Russian patent published in 2010 - IPC C23C22/00 C23C22/83 C09D5/08 

FIELD: metallurgy.

SUBSTANCE: in compliance with proposed method, metal is cleaned, subjected to conversion treatment by means of contact with conversion solution containing at least one simple or complex salt of at least one metal. Note here that conversion layer is formed that contains 0.01 to 0.07 mmole/m² of metal M. If required, is it rinsed by water and/or dried, brought in contact with coating material containing c1) from 5 to 30 wt % of one or several cross-linking burn-in urethane resins with blocked isocyanate groups. Note also that not over 5% of available carbon atoms exist in aromatic and/or unsaturated groups, c2) from 10 to 30 wt % of one or several cross-linking agents for component (c1, c3) from 4 to 30 wt % of one or several antirust pigments, the rest making one or several organic solvents and/or water, and, if required, other auxiliary substances. Produced coat is hardened by heating substrate to at least 100°C.

EFFECT: simplified procedure.
