Fisheyes on Surface After Electrophoretic Coating of Brass
We are producing door handles of brass and we have electrophoretic transparent surface coating system. Our problem is : It is fisheyes on the surface after heating the brass plates. That means : there's circles on the surface with dia 0.5 - 1 mm. We need urgently help. Thanks in advance.

Try to make contact with some of our vendors at finishing.com that sell E-coat.

Hi, Selim,
you can try to utilize the pre-baking process. I think the process can decrease the fisheyes.
Best regards,

Selim: Are your brass handles castings? Is it possible that the bake temperature needed to cure the E-coat is causing the problem usually 325-350 F for 20 minutes?
