Description
Product Overview
Stop wasting time cutting tape with scissors! Leader Masking High Temp Masking Discs are the ultimate time-saver for your production line.
We convert our industry-standard Green Polyester Tape into precision Die-Cut Dots. These are perfect for masking circular grounding areas, bolt holes, and flat surfaces. Supplied on a split-back or clear liner, they are easy to peel and apply, ensuring a perfectly round, clean paint edge every time.
Key Features & Benefits
-
🚀 Boost Efficiency: “Peel and Stick” application is significantly faster than cutting tape manually. Reduce your labor costs and masking time by up to 50%.
-
🎯 Precision Masking: Each disc is die-cut to an exact diameter. This guarantees a consistent, professional-looking circular unpainted area (ideal for Grounding/Earthing points).
-
🚫 Zero Residue: Like our Green Tape, these discs feature a premium Silicone Adhesive that removes cleanly after baking at 204°C (400°F).
-
💪 Tough & Durable: The 2-mil polyester film will not tear during removal, even under heavy powder thickness.
-
✨ Easy-Peel Design: We offer Split-Back Liners or Wishbone Handles (upon request) to make removing the dots from the backing paper effortless, even with gloves on.
