Current question:

December 20, 2021

Q. I have one problem to applying CED Coating on brass metallic surface, generally giving recommended voltage and time to brass material and giving 200 °C temperature to oven. There is problem occurring on the edge of the material that applied coating is not staying at edge of material so that the edges will remain simply and not sucked the colour. Experts please give me right solution.

A. In simple steps: Pre treatment (iron phosphate, zinc phosphate or newer nano coatings), E-coat and Bake. Not a rule but generally online de-rusting is not present in the pre treatment line. Depending upon the component and the performance expected Passivation / Sealer dip may or may not be present. A typical line could look like - Degrease, Degrease, WR, WR, Activation / Surface conditioning, Phosphating, WR, DI WR, DI WR, E-coat, Permeate Rinse, Permeate Rinse, DI WR and then bake. I hope this answers your question.

Q. Hi All,
We currently subcontract our panels for cataphoresis. Recently we have had rejects from our customer with a "marbling/running effect" down to face of the parts. Our supplier is adamant that it is the material which is at fault, but we have checked the material and can find no issue with this whatsoever. Has anybody seen/heard this issue before and found the root cause?

Material is 1 mm thick stainless steel.

A. If the raw uncoated steel does not have the same grain pattern as you are seeing over the painted surface, then the paint job or phosphating pretreatment is not good enough.
