Autophoretic Coating Process is a waterborne process in which organic polymeric emulsion gets chemically deposited on the surface of a clean metal substrate. Basics of Autophoretics: Also known as autodeposition, A-coat or AP. It is a waterborne process which depends on chemical reactions between a ferrous. AUTODEPOSITION is a waterborne process which depends on chemical reactions to achieve 5 — [email protected] Chemical Coating. Stage No. 6 — Plant.

This is a revolutionary way to meet higher performance and corrosion resistance standards at a competitive price. This diffusion control leads to a uniform coating thickness on complex shapes and in recessed areas. This process has been in commercial use since Presently, there are numerous installations in operation, both captive and job-shop, coating a variety of fabricated steel parts for the automotive and general industry markets.
Not compatible with aluminum or galvanized material. Latex films form by coalescence.
Autophoretic® Coating Process
But now we have another process reported to offer percent advantages over competitive coatings and 0 percent disadvantages. On leaving the bath, the coating consists of two layers; one is a very cohesive reacted layer; while the other is composed of undeposited excess polymer and activator from the bath.
Has anyone experience with this coating on galvanized zinc surface? Thanks for the help. The mildly acid bath liberates a small amount of iron from the steel parts being immersed, causing an immediate surface reaction that releases iron ions. The chemical reaction continues in the second layer, which results in film deposition and increased film thickness instead of solids loss to dragout.

So, if you want to replace paint, it may be a great fit. Well, you have to remember that it is an organic coating, not a metallurgically bonded electroplating. Pencil hardness of 6H to 7H.
Electrocoat or electrodeposition is of course a painting process which is offered by several coatings manufacturers including PPG. From beautiful Pine Beach New Jersey: Uniformly coats the inside and outside of tubular shapes, complex assemblies, and narrow crevices. A by-product of the heat-treating process No adhesive bonding materials such as tape, epoxy, etc.

Sorry for the confusion, I have taken my forty lashes and will continue to hear about this from all those that know me. Is not UV stable.
These criteria have been established to ensure the maximum performance on each part. No tool markers, die, bluing or coil markings. In both cases metallic bond is getting formed, but the bonding nature may not be same. Of course, that doesn’t mean that ALL parts will chip and rust! The Autodeposition process can be successfully applied to galvanized substrates.
Metal surface must be low to medium carbon, cold or hot rolled steel. So I am very glad to join this discussion. This unusual feature strongly limits carryover of coating chemicals into the rinse tanks and greatly reduces the demand for waste treatment. I’m searching for any independent research about autodeposition coating.
Free from carbon enbrittlement. This forum is for technical discussions, not promotion of one technology over another, so please tell us what are the indications when electrocoating would be a better choice. Coats evenly on all surfaces; where it flows it coats with no runs or sags.
