Die Cutting Green Polyester Masking Discs with Wishbone for PCB Masking

Short Description:

Our Green Polyester Masking Discs are high-performance, die-cut discs made from durable polyester film with a silicone adhesive. These discs are designed for precise masking in high-temperature applications, such as powder coating, plating, and PCB masking. They can withstand temperatures up to 400°F and provide excellent protection during oven curing or other challenging processes. Typically placed on a clear, slit-back liner for easy removal, polyester masking discs ensure reliable adhesion and clean removal without residue.
