ABSTRACT:
Substantially improved retention of hydrophilicity after exposure to high temperature can be provided on a metal substrate, particularly an aluminum alloy of the type used for heat exchanger fins by an aqueous liquid hydrophilicizing treatment composition containing acrylic and/or methacrylic acid polymer or copolymer, polyether alcohol, and alkali metal silicate. The treatment composition may also contain an anti-microbial agent and additional alkalinizer. The hydrophilicizing treatment is preferably applied over a conventional conversion coating, particularly a chromium phosphate or chromium oxide conversion coating.
