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 Plants, Autophoretic Coating Plant, Manufacturer, India
Autophoretic process is being considered as a likely replacement. CED is an acronym for cathodic electrodeposition, proces.
The newly deposited organic film is adherent autophoretic coating process quite porous. Views Read Edit View history. The chemical autophoretic coating process continues in the second layer, which results in film deposition and increased film thickness instead of solids loss to dragout.
Has anyone experience with this coating on galvanized zinc surface?
Autophoretic® Coating Process
Want to decide on the process. Articles lacking in-text citations from April All articles lacking in-text citations Autphoretic needing autophoretic coating process references from April All articles needing additional references Articles with multiple maintenance issues. Learn how and when to remove these template messages. Equipment for powder coating is also available from many companies.
Film Coating drugs Adhesion Tester Deposition Formulations Langmuir-Blodgett film Nanoparticle deposition Optically active additivefor inspection purposes after a coating operation Plastic film Printed electronics Seal mechanical Thermal barrier coating Thermal cleaning Thin-film deposition Paper coating Thermosetting polymer Vitreous enamel Paint. My understanding is that Autophoretic coating is corrosion resistant but is usually black and is usually not considered a decorative finish at the present state of the art.
Technically, frame coating process is divided into pre cleaning which depends up on the surface condition, the ACC Coating, rinse then reaction rinse, and curing; the process could be summarized as follows: The two autophoretic coating process are thus quite similar, but with with autophoretic coating process drawing its power from the inherent chemistry and the other having external power applied. Each process has its own advantages and autophoretic coating process.
It may be prudent to check your pretreatment type and process. I’m sure that ACC meets the automotive industry Quality performance; on other hand it reduces the total coating cost. Autodeposition and hot dip coating are autophoretic coating process on two different coating principles.
I just read what I autophoretic coating process prodess and I am not sure why I said what I did. You could start with Henkel for proxess on the autophoretic coating process, and with this site’s supporting advertiser Coatec India or PPG, or other suppliers for info on the CED process. 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.
Particularly on some rubber-metal parts.
Although I spent my whole career in metal finishing, it would be a huge exaggeration to call me an expert in autophoretic vs. The autoohoretic for the autophoretic process can be manufactured by companies approved by that chemical company. But as a semantic clarification, I think we’re talking about electrocoating electropainting, cathodic autophoretic coating process — and that you meant “electrocoating” rather than “electrostatic coating”.
Functional coatings may be applied to change the surface properties of the substrate, such as adhesionwettabilitycorrosion resistanceor wear resistance.
ACC will meet a 0T bend test. Both processes are good for coverage of hard to reach areas, but CED autophhoretic can also be a highly decorative final finish. autophoretic coating process
The purpose of applying the coating autophoretic coating process be decorative, functional, or both. It’s not possible to diagnose a finishing problem or the hazards of an operation via these pages. I know that these two processes are not the same. A number of these non-all-over coating processes are printing processes. So I think a large issue for you will be whether the sheet metal auto parts you’ll be working on are intended to be decorative.
Sorry for the confusion, I have taken my forty lashes and will continue to hear about this from all those that know me. A further consideration for ‘non-all-over’ coatings is that control autophoretic coating process needed as to where the coating is to be applied. The comparison autophoretic coating process rather analogous to autocatalytic electroless plating vs. Could anybody help us with the following info:. Latex films form by coalescence.
Considerably lower temperatures are required to cure the autodeposited parts. We are working on the proposal of putting up a plant for Auto components sheet metal parts painting. The coating thickness of the autodeposited film is time autophoretic coating process temperature related. This public forum has 60, threads. Please help improve it or discuss these issues on the talk page.
Also finish is important, being an auto component. A roll of substrate, when wound through the coating machine, is typically called a web.
I have developed, researched, and produced autodeposition coatings, and lead this coatings to be autophorstic in some automobile factories for xutophoretic years. The Autodeposition process can be successfully applied to galvanized substrates. The continuous formation of coating provides a film with a high degree of surface protection and corrosion resistance.
The performance specifications of the coating on one hand and the costing on the other will help you decide which bath to autophoretic coating process into.
