ABSTRACT:
A method of treating inorganic materials such as metals to ensure strong adhesion of a subsequently applied coating of another material, such as a paint, comprises the steps of applying to a surface of the material a composition containing a complexing agent comprising both a sulph-hydro and a carboxylic acid group and applying over the complexing agent a film-forming coating which also contains a complexing agent comprising both a sulph-hydro and a carboxylic acid group and/or an anti-oxidant.
