E-Coating process International Specifications?

#1
Hello, is there an international specification that give guidelines for e-coating parameters e.g. alkaline degreaser temp/PH, curing temp? bath conductivity levels?

It has been a long time since I was involved in e-coating. We had customer standards from Mazda on the performance of the coating, but do not recall any standards (other than internal) on the processing and surface prep.

Hello Zanele ,

There is NO spec as such that I know of, but:

The parameters of your process must be defined according to the product specifications, for example: the thickness of the paint. In addition, the parameters of an E-coat line will be different from each other, this will depend for example: the number of immersion or spray rinse tanks, conditioners, color seals, permeate, etc. The immersion time in each tank and the total cure time are also taken into account.

I know of some paint suppliers, who provide technical support on their e-coat lines to help you define parameters that help meet your product specifications, and also perform chemical checks on their tanks, they also include initial tests and trials. Annual route due to corrosion, curing, adhesion, etc. (It is part of the service).

Greetings!
