Abstract: This invention relates to an autodeposition bath composition comprising a nitrogen containing compound, said bath being suitable for generating a uniform autodeposition coating on two or more of ferrous, aluminum, magnesium and zinciferous multi-metal substrate surfaces, treated either sequentially or simultaneously. The invention also provides autodeposition concentrate compositions for use in the bath, methods of making and using the concentrate and bath, as well as metal articles comprising an autodeposition coating according to the invention.

Abstract: This invention provided an aqueous coating composition for metal surface pre-treatment comprising: (i) at least one organosilane with at least one hydrolyzable substituent; (ii) at least one water soluble and/or water dispersible silane-functional oligomer; (iii) at least one water-soluble compound of the elements Zr and/or Ti; The resultant sol-gel coating composition reveals an extended shelf life and after surface pre-treatment using the invented coating compositions the metal substrates have higher resistance to corrosion, humidity and solvent and at the same time have better surface conductivity and paintability.

Abstract: The invention provides an improved appearance, glossy, autodepositing coating composition that maintains its desirable properties such as moisture barrier properties, although it is still able to deliver a glossy finish. No additional coatings are necessary over the instant coating to achieve a gloss. The glossy composition is accomplished by narrowing the molecular weight distribution and the molecular weight of an autodepositing epoxy dispersion coating by adding a chain transfer agent. The chain transfer agent is a thiol-containing compound made from an epoxy resin mixed with at least one ethylenically unsaturated monomer polymerized through a polymerization process, a curing agent, and a starter composition of peroxide, FeF3, and hydrofluoric acid. By eliminating the starter composition, a bath concentrate suitable for selling is manufactured.

Abstract: Novel low viscosity oligomeric polyols and the use thereof in coating compositions are disclosed. The novel low viscosity oligomeric polyols may be prepared by reacting at least one melamine aldehyde resin and at least one of ?,?-diol, ?,?-diol, or mixture thereof. The reaction may occur in the presence of an acid catalyst. Coating compositions with a low VOC able to cure under ambient and forced dry conditions while providing good application and performance characteristics, such as an improved scratch resistance, are also disclosed.
