Dissolve Powder Coating, Solvent for Powder Coating


(2001)

How do you dissolve a powder coating?

I have some center rings (with a raised design on them) for writing pens. The writing pens have a 'recessed' area that can be filled with any art/craft material. The center rings start as brass rings, are then plated in 24k gold, then the relief around the design is done in black powder coating. But, my customers say this 'design' (black & gold) doesn't go well with the art/craft materials they put on the pens. How can I get the black off without disturbing the 24k gold underneath?

Thank you, Toika USA

Hi

Assuming that the powder is polyester or epoxy polyester buy some BENZYL ALCOHOL and dissolve up 10 g/l potassium hydroxide in it. The solution will work cold and the powder literally dissolves off
