20130266814 | GLOSSY IMPROVED APPEARANCE AUTO-DEPOSITION COATING, AND METHODS OF APPLYING SAME - 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. | 10-10-2013 |

20130316171 | CO-CURE PROCESS FOR AUTODEPOSITION COATING - A coated article comprising a metal surface, a first layer of an uncured autodeposition coating and a second uncured paint layer deposited sequentially on the surface without intermediate curing of the autodeposition coating, a process of co-curing said autodeposition coating and paint layer or layers, and a cured coated article having chemical bonds between the cured autodeposition coating layer and at least the cured paint layer immediately adjacent to the cured autodeposition coating layer. | 11-28-2013 |
20140234641 | SINGLE BATH AUTODEPOSITION COATING FOR COMBINATION METAL SUBSTRATES AND METHODS THEREFOR - 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. | 08-21-2014 |
