Abstract: An aqueous liquid passivate composition for treating metal surfaces having dispersed therein solid particles which result in a transparent or translucent, preferably colorless, corrosion resistant coating, upon drying of the aqueous liquid passivate composition, the coating providing better resistance to heating by solar energy than the untreated metal surface at lower coating thicknesses than paint.

Abstract: Storage-stable organic passivate formulations that are essentially chromium-free are provided comprising non-ionic or non-ionically stabilized organic film forming resin; at least one complex fluoride and optionally, dissolved phosphate anions, at least one component comprising vanadium, at least one inorganic oxide in dispersed form; and at least one wax in dispersed form.

Abstract: The invention provides high solids epoxy-based autodeposition coating materials that have improved moisture barrier properties and/or anti-corrosive properties and a means to obtain the high solids epoxy-based autodeposition coating materials that eliminates/minimizes the need for process solvents. A hydrophobic water barrier enhancing agent, epoxy pre-polymer and ethylenically unsaturated monomer, as an alternative to organic solvent, are combined to yield an epoxy pre-polymer-monomer-hydrophobic water barrier enhancing agent blend, which may be blended with other coating components and additives. The resulting blend is then dispersed in water with surfactant and the ethylenically unsaturated monomer is polymerized (in the presence of other formulation components) to yield a dispersion. The dispersion may then be used as one component of a coating formulation. The coating formulation can then be applied to materials and cured to form a final coating.
