Abstract
The subject invention relates to compositions of matter for treating aluminum surfaces for rendering them tarnish and corrosive resistant. The compositions comprise an alkali metal silicate including sodium and potassium and lithium silicates and a soluble organic polymer having displaceable hydrogens or displaced hydrogens. The organic polymers having displaceable hydrogens may be derived from hydroxyls, carboxylic acids, amides, sulfonic acids, carbohydrates, and phosphoric acids. The composition may be readily applied by spraying or dipping them in concentration less than about 5% in an aqueous system.
