Titanium Racks in Chromic Acid Anodize


We try to adopt the use of Titanium racking in Chromic Acid Anodizing.

The problem is that the Titanium racks draw by themselves, large amounts of current and the capacity of our rectifier is highly consumed by the racks.

Can you possibly give us some advise on how can we deal with this problem?

The best way would be to dip coat the racks in plastisol. Alternative would be to spray plastisol coat. That is a slightly different product. It is a pain to apply, but can be done if you exactly follow the instructions. It will require masking off part of your rack as it is moderately difficult to remove.

Other vinyl type pain on coatings may do ok also. Tolber, a div of Pyramid plastics, a div of Michigan chrome and chemical (Hope AR) makes a product called Super XP 2000 that is quite good. There is probably a similar product sold in Europe.
