Star Bursts in the Coating
5/14/2012 Products Finishing
We are using a wrinkle dark gray powder and often have a problem with “star bursts” all over the product. The stars are visible in the dry film and they do not flow out in the cure oven. We also spray a wrinkle black and get this problem occasionally, but it is not so pronounced. We do not have this problem with our smooth powders. We have cleaned the powder booth and the fee hopper, changed filters and everything else we can think of, but we cannot make the problem go away. Do you have any suggestions?

Clear Coat Over Silver Powder
4/10/2012 Products Finishing
I had a commercial applicator powder coat a luggage rack for a motorcycle, applying one coat of a silver color and then a topcoat of clear powder. A few months later, the clear finish cracked. The motorcycle is garage-kept. I consulted with another powder coating company, which said the powder was probably not polyester-based. Would polyester be best in this application? Do all silvers have to be clear-coated? Do only silvers need clear coat?
