The present invention uses titanate compounds to replace chromates in metal primer paints used for corrosion protection on metal substrates.

Non-chromate primer for painting

Non-chromate solutions for treating and/or etching metals, particularly, aluminum, aluminum alloys, steel and titanium, and method of applying same wherein the solutions include either a titanate or titanium dioxide as a 'drop-in replacement' for a chromium-containing compound in a metal surface etching solution that otherwise would contain chromium.

Chromate-free method for surface etching of stainless steel

Chromate-free method for surface etching of titanium

Chromate-free method for surface etching of aluminum and aluminum alloys

A coating composition which contains a polymeric complex between polyaniline and a polymeric ion. In addition to the said polymeric complex, the composition contains a water-dispersable binder. The composition is useful as a water-borne paint to be applied onto a metal substrate electrophoretically or non-electrophoretically.

Water-borne polymeric complex and anti-corrosive composition

Non-chromate solutions for treating and/or etching metals, particularly, aluminum, aluminum alloys, steel and titanium, and method of applying same wherein the solutions include either a titanate or titanium dioxide as a &ldquo;drop-in replacement&rdquo; for a chromium-containing compound in a metal surface etching solution that otherwise would contain chromium.

Non-chromate metal surface etching solutions

A non-chromate conversion coating and method of applying same wherein the coating comprises a titanate, such as potassium titanate or sodium metatitanate, as a &ldquo;drop-in replacement&rdquo; for a chromate in an otherwise chromate-containing conversion coating.

Non-chromate conversion coatings

An anti-corrosive polymeric complex which is comprised of a plurality of double-stranded molecular complexes. Each of the molecular complexes are comprised of a strand of a conductive polymer and a strand of a copolymer. The strands of the polymeric complex are non-covalently bonded to each other along the contour of the strands to form a side-by-side, twisted, double-stranded configuration.

Electroactive polymer coatings for corrosion control

A junction photodetector employing Pb.sub.1-x Sn.sub.x Te in narrow film strips grown epitaxially on an appropriate substrate. An appropriate metal overlaps the film to form a metal-semiconductor contact.
