Need info on applying Nylon 12 E-Coatings
Q. Hello,
I work for a Mfr. Rep. firm out of Alpharetta Ga. We specialize in plastic materials, and cover the Southeastern part of the U.S. I recently made a call on a metal finishing company in our territory who was asked to quote an E-Coat job involving Nylon 12. This company asked if I'd try to assist them in finding out more information on such a coating. Does anyone have any information that they may be willing to share with me in this regard.
Many Thanks,

A. If I understand correctly, you want E-coat on a Nylon 11 substrate. If this is correct, E-coat can only be used to coat electrically conducting substrates. Also why in the first place does your customer require E-coat on Nylon 11 components?

A. Hi. There has probably been a miscommunication early on, Drew. I think you asked about e-coating Nylon 12 onto something, whereas Gurwin, with his knowledge that there is no such thing as Nylon 12 e-coating, assumed that you must want to do e-coating onto a nylon substrate.
Here's my guess as to what happened: the customer asked for electrostatic powder coating of Nylon 12 onto their parts and, somewhere along the line, someone assumed that "e-coating" is an abbreviation for "electrostatic powder coating" and started using that term. It's not: "e-coating' is an abbreviation for "electrocoating", a dip process where electricity is applied to the component and the electricity chemically oxidizes or reduces organic ions in the solution, converting them into a coating somewhat like paint.
My bet is you are looking for electrostatic powder coating of Nylon-12 onto a metal component. Good luck confirming that and sorting it out.

Q. Do you have any brand specific nylon materials that you would recommend that can go through the e-coat process?

A. Hi Ted. What do you mean by "go thorough"? Do you perhaps simply mean materials of construction for accessories that can survive the process without being chemically attacked? Nylon is not in general an ideal material of construction for wet processing because of its absorption properties, and its limited resistance to acids and alkalies. PVC and polyolefins are probably better choices. Good luck.
