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? Pencil hardness of 6H to 7H. Sorry for the confusion, I have taken my forty coatinng and will continue to hear about this from all those that know me. 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.

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 able to process zinc substrates and not plain steel at the same time.

Free from carbon enbrittlement. From beautiful Pine Beach New Jersey: Metal surface must be low to medium carbon, cold or hot rolled steel.

One through electric circuit another without. But in case of electrocoating, the surface atom of the lattice may form bond with foreign atoms. A by-product of the heat-treating process No adhesive bonding materials such as tape, epoxy, etc.

So, if you want to replace paint, it may be a great fit. 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.

Presently, there are numerous installations in operation, both captive and job-shop, coating a variety of fabricated steel parts for the automotive procesz general industry markets.

This unusual feature strongly limits carryover of coating chemicals into the rinse tanks and greatly reduces the demand for waste treatment. It’s not possible to diagnose a finishing problem or the hazards of an operation via these pages. High corrosion resistance Generally hrs. It’s one more tool in the arsenal, and will fill the needs some of the time; but you have to look at the actual parts and the actual service conditions. coatinf

The chemical reaction continues in the second layer, which results in film deposition and increased film thickness instead of solids loss to dragout. The Autodeposition process can be successfully applied to galvanized substrates. Initially, the deposition process is quite rapid, but slows down as the film increases in thickness.

This is a revolutionary way to meet higher performance and corrosion resistance standards at a competitive price. The newly deposited organic film is adherent yet quite porous. In hot dip coating, where Zn getting may be diffused into the lattice structure of the Fe and get attached simple substitution.

Well, you have to remember that it is an organic coating, not a metallurgically bonded electroplating. So I am very glad to join this discussion. Thanks for the help. This diffusion control leads to a uniform coating thickness on complex shapes and in recessed areas. Ajtophoretic coating procesx of the autodeposited film is time and temperature related.

Not compatible with aluminum or galvanized material. These criteria have been established to ensure the maximum performance on each part. Please contact your local PPG office for that paper. Latex films form by coalescence. If the condition of the received materials deviates from the above stated criteria, performance suffers significantly.
