Powder Coat Used As A Plating Maskant

Q. I know you do not make recommendations for specific commercial powder coatings but maybe you can point me in the right direction. I want to use a powder coat as a maskant for our nickel plating process. It would have to be able to survive strong acid (pH as low as 2.0) and temperatures of up to 150°F (up to 200° for electroless but that is not necessarily a requirement). Additionally, abrasion resistance would be beneficial. Any suggestions would be appreciated. W. H.
A. Plating rack suppliers have been using PVC to mask plating racks for many years. This thermoplastic material is available in both powder and liquid form. I am sure it will suit your purposes for masking in your nickel plating process, as it is very acid resistant, abrasion resistant and temperature tolerant up to +200°F. It can be removed from your product after plating using either heat or mechanical removal techniques, as is done when plating racks are refurbished.
Infrared cure is gaining increased attention from coaters as a result of shorter cure cycles and the possibility of smaller floor space requirements when compared to convection oven curing.
Question: What methods are available for removing cured powder coatings, and what are the pros and cons of these methods?
Choosing the right conveyor system, coating technology, and ancillary equipment.
