The bath viscosity is close to that of water with little or no organic solvents in the coating bath. Another characteristic of the Autophoretic® coating process is that. Autophoretic Coating Process is a waterborne process in which organic polymeric emulsion gets chemically deposited on the surface of a clean metal substrate. Has anyone ever used or know anything about the Autophoretic® Coating Process? Thomas Moffitt. Massachusett’s Office of. Technical Assistance, Boston, MA.

Autophoretic® Coating Process

Each process has its own advantages and disadvantages. The performance specifications of the coating on one hand and the costing on the other will help you decide which bath to dip into. This article includes a list of referencesbut its sources remain autophkretic because it has insufficient inline citations. Electrocoating is another means of coating truck and auto frames.

CED, which means “cathodic electrodeposition”, is a type of electrophoretic deposition wherein the work is cathodic. The two processes are thus autophoretic coating process similar, but with with one drawing its power from the inherent chemistry and the other autophoretic coating process external power applied.

Articles sutophoretic in-text citations from April Autophoretic coating process articles lacking in-text citations Articles needing additional references from April All articles needing additional references Articles with multiple maintenance issues. I’m searching for any independent research about autodeposition coating. Of course, that doesn’t mean that ALL parts will chip and rust!

Want to decide on the process. An example of all of these types of coating is a product label on many drinks bottles- one side has an all-over functional coating the adhesive and the other side has one or more decorative autophoretic coating process in an appropriate pattern the printing to form the words and images.


Autophoretic Coating Process

The comparison is rather analogous to autocatalytic electroless plating vs. This diffusion control leads to a uniform coating thickness on complex shapes and autophoretic coating process recessed areas. Are there procedures in place to preclude hydrogen damage autophoretic coating process such parts? Initially, the deposition process is quite rapid, but slows down as the film increases in thickness.

But in case of electrocoating, the surface atom of the lattice may form bond autophoretic coating process foreign atoms. Autodeposition and hot dip coating are based on two different coating principles. In some speciality shops the preferred method of painting truck and car frames is powder coating.

April Learn how and when to remove this template message. The autolhoretic thickness of the autodeposited film is time and temperature related.

Since its inception, this unique process has been employed to coat billions of square feet of surface. December 7, A. Autophoretic coating process excellent point does seem to apply to e-coating of the I. Thanks for the insights on the advantages of autophoretic coating. autophoreic

However it is not with typical bath chemistry and requires some additional considerations due to the build up of zinc in coating bath. Autophoretic coating process not trying to give anyone a hard time, but finishing.

ACC will meet a 0T bend test.

We have two lines running with ACC. Autophoretic coating process contact your local PPG office for autophoretic coating process paper. Second line has just been commissioned for heavy vehicle brake plates. Typically, film thickness is controlled from 0. So I am very glad to join this discussion. The equipment for the autophoretic process can be manufactured by companies approved by that chemical company.

Learn how and when to remove these template messages. Parts up to approx. On leaving the bath, the coating consists of two layers; one is a very autophoretic coating process reacted layer; while the other is composed of undeposited excess polymer and activator from the bath.


It’s one more tool in the arsenal, and will fill the needs some of the time; autophoretic coating process you have to look at the actual parts and the actual service conditions. The purpose of applying the coating may be decorative, functional, or both. A number of these non-all-over coating processes autophoretic coating process printing processes. Since this process involves a mild acid acting on the base part, can it result in delayed cracking under stress from hydrogen damage on a quench and tempered part as with other processes i.

By using this site, you agree to the Terms of Use and Privacy Policy. Autophoretic coating has sort of a spring-loaded chemistry that reacts with the metal, causing chemical changes in the coating materials in the tank that result in deposition of the coating onto the substrate. A further consideration for ‘non-all-over’ coatings is that control is needed as to where the coating is to be applied.

But now we have another process reported to offer percent advantages over competitive autophoretic coating process and 0 percent disadvantages. If you cannot pass this test, you may have a pretreatment problem. The equipment for this process can be manufactured by many companies.

But as a semantic clarification, I think we’re talking about electrocoating electropainting, cathodic electrodeposition — and that you meant “electrocoating” rather than “electrostatic coating”. Thanks for the help.
