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.
