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.

Description of Autophoretic®

Coats evenly on all surfaces; where it flows it coats with no runs or sags. Typically, film thickness is controlled from 0.

Has anyone experience with this coating on galvanized zinc surface? No tool markers, die, bluing or coil markings. This is a revolutionary way to meet higher performance and corrosion resistance standards at a competitive price. We looked 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. The line would most likely only be able to process zinc substrates and not plain steel at the same time.

The continuous formation of coating provides a film with a high degree of surface protection and corrosion resistance.

So I am very glad to join this discussion. Initially, the deposition process is quite rapid, but slows down as the film increases in thickness. The metal surface of the part requires only cleaning and rinsing to prepare for the chemical reaction to take place; NO electrical charge or pre-coat is required. A by-product of the heat-treating process No adhesive bonding materials such as tape, epoxy, etc.

From beautiful Pine Beach New Jersey: These ions interact with the latex in solution causing coating deposition on the surface of the steel parts. The coating 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.

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.

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. It’s not possible to diagnose a finishing problem or the hazards of an operation via these pages. Sorry for the confusion, I auyophoretic taken my forty lashes and will continue to hear about this from all those that know me.

High corrosion resistance Generally hrs.

Is not UV stable. Are there procedures in place to preclude hydrogen damage in such parts? Metal surface must be low to medium carbon, cold or hot rolled steel. These criteria have been established to ensure the maximum performance on each part.

The Autodeposition process can be successfully applied to galvanized substrates. I just read what I wrote above and I am not sure why I said coaating I did. The ocating of these stages leads to considerable savings in required floor space, energy, and operating costs, as well as the total elimination of toxic metals from the process.

Free from carbon enbrittlement. I have developed, researched, and produced autodeposition coatings, and lead this coatings to be applied in procesa automobile factories for many years.

But in case of electrocoating, the surface atom of the lattice may form bond with foreign atoms. This diffusion control leads to a uniform coating thickness on complex shapes and in recessed areas.

Autophoretic® Coating Process

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. This unusual feature strongly limits carryover of coating chemicals into the rinse tanks and greatly reduces the demand for waste treatment. Coating may be bent back on itself with no cracking or peeling.

Please contact your local PPG office for that paper. In both cases metallic bond is getting formed, but the bonding nature may not be same. Pencil hardness of 6H to 7H. In hot dip coating, where Zn getting may be diffused into the lattice structure of the Fe and get attached simple substitution. Second line has just been commissioned for heavy vehicle brake plates.
