Powder Coating Clinic: Masking for Logo Design

Q. We are powder coating stainless steel water bottles for our company. For our logo, we would like to use a vinyl sticker or decal before powder coating. After the coating is applied, we want to peel the vinyl off to achieve a stainless steel logo effect, so we need some kind of temperature-resistant vinyl. Any suggestions?

A. You could use high-temperature polyester tape. It will take up to 425°F in the oven, and it can be made in die-cut forms for your logo. You can find it from supply sources that can be researched through PFonline.com by searching “masking supplies” or “high-temperature masking tape.” There is one caution that is always offered about masking with powder coating: When you remove a masking tape after coating, the parting line at the edge of the tape may leave a rough edge. Powder is a relatively thick coating and may be a little ragged at the line due to bridging over the edge of the mask. A thinner coat will help. It may also be possible to carefully remove the mask before you cure. There is a risk of leaving some small particles on the masked area as the dry material breaks free when you remove the mask. Try some samples to see what works best.
