FIELD: chemistry.
SUBSTANCE: conversion composition is proposed for applying a substrate to a metal containing a complexing agent for metals in the amount of 0.005 g/1000 g of the composition to 3 g/1000 g of the composition capable of binding and/or removing copper and/or iron from the metal surface, a metal cation and an aqueous carrier. A coated product and a method of its production are also proposed.
EFFECT: composition provides removal of copper or iron from treated metal surface, as well as subsequent production of conversion coating that increases corrosion resistance of the metal surface.
