Nucleus formation in solvent based coating in electrosatatic coating

2005

Dear Sirs,

I am painting glass tumblers in an electrostatic disc. Often I face with nucleus formation (small bubble-like things)on coating. The amount of these changes every time and I can not control the amount by cleaning, by preparing new paint etc. Actually what I need is to get rid of all of them but some paint makers say this is the nature of electrostatic coating.

I really appreciate if you can share your opinions and experiences and ideas.

Best regards,

Mr. Erdem,

Not enough information. Do the bubbles look like the eye of a fish? I paint Steel, Zinc, ABS, PC/ABS and PC not glass so you might be experiencing something I'm not familiar with, but it sounds like you may be experiencing a cleaning problem. If I get something like you describe I walk the line and pay particular attention to part cleanliness.

Good Luck
