“I work for a leading manufacturer of recirculating baths and chillers. We are currently bringing a white powder coating operation in-house. Case assemblies with this white polyester powder coat receive a teal band with the company logo and model, which is screen printed onto the case. My question is: what types of ink will exhibit strong adhesion and scratch resistance to a polyester powder? Our current air dry ink is fine for text and symbols but is not durable enough for a 2″ x 6″ band.”

“Your powder coating supplier will have the answer for you. It is important that you tell him/her that you intend to silk screen over the powder, since they must modify the formulation to accommodate this. They may tell you that the powder material that you have selected will not accept a silk screen ink. If it does, then they can tell you which inks are the most appropriate.”
