AUTOPHORETIC COATING PROCESS PDF

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.

Has anyone experience with this coating on galvanized zinc surface?

Autophodetic newly deposited organic film is adherent yet quite porous. The bath viscosity is close to that of water with little or no organic solvents in the coating bath.

The line would most likely only be procss to process zinc substrates and not plain steel at the same time. If not, I’m not so sure that this work would have legitimate scholarly value: The continuous formation of coating provides a film with a high degree of surface protection and corrosion resistance.

If you try our search engine, I’m sure you can find some more. This unusual feature strongly limits carryover of coating chemicals into the rinse tanks and greatly reduces the demand autophorstic waste treatment. A by-product of the heat-treating process No adhesive bonding materials such as tape, epoxy, etc. Withstands nicking and marring for better handling.

Autophoretic® Coating Process

The chemical reaction with the metal and the paint flows quickly as the film builds providing a self-limiting feature which results in a uniform thickness for the entire part. Thomas Moffitt Massachusett’s Office of Technical Assistance, Boston, MA Well, you have to remember that it is an organic coating, not a metallurgically bonded electroplating.

We have two lines running with ACC. We pocess at it for replacing some heavy zinc plating on couplings and had to dismiss it because the parts are handled very roughly and will chip and rust.

Since its inception, this unique process has been employed to coat billions of square feet of surface.

Not compatible with aluminum or galvanized material. This is a revolutionary way to meet higher performance and corrosion resistance standards at a competitive price. Autodeposition and hot dip coating are based on two different coating principles. This diffusion control leads to a uniform coating thickness on complex shapes and in recessed areas. Are there procedures in place to preclude hydrogen damage in such parts? This allows the coating dispersion to flow into and around the most complex shapes.

The coating thickness of the autodeposited film is time and temperature related. Coating may be bent back on itself with no cracking or peeling. From beautiful Pine Beach New Jersey: Depends on solvent, time, and temperature. Unlike coating processes that require a charge to deposit the coating i. These criteria have been established to ensure the maximum performance on each part.

All information presented is for general reference and does not represent a professional opinion nor the policy of an author’s employer. The chemical reaction continues in the second layer, which results in film deposition and increased film thickness instead of solids loss to dragout. Latex films form by coalescence. Second line has just been commissioned for heavy vehicle brake plates. Presently, there are numerous installations in operation, both captive and job-shop, coating a variety of fabricated steel parts for procews automotive and general industry markets.

Free from carbon enbrittlement. However it is not with typical bath chemistry and requires some additional considerations due to the build up of zinc in coating bath. In both cases metallic bond is getting formed, but the bonding nature may not be same. Uniformly coats the inside and outside of tubular shapes, complex assemblies, and narrow crevices. These ions interact with the latex in solution causing coating deposition on the surface of the steel parts.

High corrosion resistance Generally hrs. One through electric circuit another without. Initially, the deposition process is quite rapid, but slows down as the film increases in thickness. Pencil hardness of 6H to 7H. Coats evenly on all surfaces; where it flows it coats with no runs or sags. Sorry for the confusion, I have taken my forty lashes and will continue to hear about this from all those that know me.

No compounds or lubricants containing animal fat, paraffin, detergents or silicate ingredients.

Metal surface must be low to medium carbon, cold or hot rolled steel. So I am very glad to join this discussion.

Well, you have to remember that it is an organic coating, not a metallurgically bonded electroplating. 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.

But now we have another process reported to offer percent advantages over competitive coatings and 0 percent disadvantages.
