Switching to Powder

We are a custom powder coater and a customer of ours wants to switch from e-coat to powder coat on his zinc parts. Is there something that either we, or our customer, can do to assure these zinc parts will have adequate and consistent adhesion? We coat aluminum and steel all day long and do not have these adhesion problems.

Powder Coat Stainless Steel

I work for an Indian company, a leading solar panel manufacturing company. We are required to powder coat stainless steel grade SS430, 2B finish. I would like to know what the process is for this and what would be the durability of such powder coat on stainless steel base.

Powder Coat Used As A Plating Maskant

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.

Removing Rust, Mill Scale And Oils In One Step

I always see the typical pretreatment stages to be a cleaner, rinse, phosphate, rinse, sealer, rinse or not. Nowhere do I see anything to deal with the rust and mill scale from the HRS steel. Is there a product that removes the rust, mill scale and oils in one step? Or are there more steps required, I can honestly say most everything I ever read about seems like a perfect world where the only thing the steel has on it is oils.

Can you powder coat a brass chandelier? How can I find a shop to perform this work?

Blisters And Creep On Aluminum Castings

We have repeatedly failed a 336-hour salt spray test on an aluminum casting. We use an immersion bath iron phosphate conversion coating (soap, rinse, phosphate, rinse) and urethane powder coating. The results have consistently been blisters and significant creepback from scribe. How can we improve our adhesion and weather resistance on these die castings? What is causing the blistering? We could instead use a TGIC Polyester? Would these powders perform better?
