ABSTRACT:
An aqueous metal surface treatment composition comprising the following ingredients:(A) an aqueous dispersion of a phenolic resin that includes a reaction product of(i) a phenolic resin precursor;(ii) a modifying agent, comprising a hydrocarbyl moiety bonded to at least one functional moiety that enables the modifying agent to react with the phenolic resin precursor; and at least one ionic moiety comprising an ionizable sulfur or phosphorous group; and(iii) at least one multi-hydroxyphenolic compound; and(B) optionally an acid where (iii) in (A) is optional where the reaction product contains two or more reactive phenolic methylol groups.
