CA 2172614

The invention relates to a nonabrasive corrosion-resistant, hydrophilic coating on aluminum sheet such as fin stock, produced by applying to the sheet surface a coating material containing, in an aqueous vehicle, effective amounts of nitrilotrismethylenetriphosphonic acid, phosphoric acid, and borate material of the group consisting of zinc borate and sodium borate, and essentially free of silica, alumina and precursors thereof, and heating the surface to establish the coating thereon. The coating formulation may also contain up to about 1 wt. % of polyacrylic acid and a surfactant to aid in application.

L'invention concerne un revêtement hydrophile non abrasif résistant à la corrosion pour des tôles d'aluminium utilisées par exemple dans la fabrication d'ailettes. On produit le revêtement selon l'invention en appliquant sur la surface de la tôle un matériau d'enduction contenant, dans un véhicule aqueux, des doses efficaces d'acide nitrilotriméthylènetriphosphonique, de l'acide phosphonique, et une matière boratée du groupe comprenant le borate de zinc et le borate de sodium, et ne contenant ni silice, ni alumine, ni précurseurs de ces derniers. On chauffe ensuite la surface avant d'y appliquer le revêtement. La formulation du revêtement peut également comprendre jusqu'à environ 1 % en poids d'acide polyacrylique et un agent tensioactif facilitant l'application de celui-ci.
