Hi, Milan. Please try your best to describe your situation and your interest in these issues rather than presenting a dry flash-card quiz :-)

I believe that many e-coats these days are cationic urethanes. The coating is very thin, as little as approximately 10 microns -- that's one of the advantages of e-coating. However, it is not unusual to apply a polyurethane or powder coating over the e-coat. Thanks!

Hi Sir,
For this information I think it is better to consult your local chemical supplier.

Dear Mr Patel,

The material is either water based epoxy or acrylic primer.
PPG, Kanzai, BASF, Dupont are some of the chaps who make the product. The normal thickness applied is around 20 microns thick.

Hope this helps you find whatever you're looking for.
