    Abstract: A corrosion-protection composition that generally includes a water-soluble trivalent chromium salt and a water-soluble polymer is disclosed. The composition preferably is in the form of an aqueous solution (i.e., the composition additionally includes water as a solvent) that can be applied to an active-metal substrate to form a coated substrate and a corrosion-protection film upon drying. Additional ingredients in the corrosion-protection composition can include a second water-soluble salt (e.g., cobalt, manganese, nickel, and/or iron salts), a crosslinking agent, and/or a coloring agent. The corrosion-protection composition is substantially free of hexavalent chromium, capable of forming a film on an active-metal substrate, and is substantially non-reactive with the active-metal substrate. Once applied, the corrosion protection-film is resistant to moisture.

    Abstract: Compositions and processes are disclosed for producing improved electrical insulation, environmental protection, corrosion resistance and improved paint adhesion for metals; e.g., ferrous, aluminum, or magnesium alloys; as well as other substrates such as anodized metals, glasses, paints, plastics, semiconductors, microprocessors, ceramics, cements, silicon wafers, electronic components, skin, hair, and wood upon contact. The compositions and processes comprise use of one or more Group IV-A metals, such as zirconium, in combination with one or more non-fluoanions while fluorides are specifically excluded from the processes and compositions above certain levels. The processes can contain pretreatment stages that serve to activate a substrate surface and/or promote formation of metal- and mixed-metal oxide matrices through use of an oxygen donor. The compositions are at a pH below about 5.0 and are preferably in a range between about 1.0 and about 4.0. The coatings may contain additives such as surfactants, sequestering agents, or other organic additives for improved corrosion protection and paint adhesion. The substrate may be treated by immersion, spray, fogging or rollcoat and other common application techniques.
