Polyester Target Line Square Stickers are made with a thin layer of polyester and a layer of silicone-based glue. Polyester Target Line Square Stickers are general purpose heat resistant tapes. They are excellent for powder coating processes, and can withstand temperatures up to 220 degrees Celsius. The target line design is great for pinpointing areas of interest, thus saving time. The stickers have a slit, making removal easy. Shown here are stickers with square dimensions ranging from 10mm to 50mm.
