High Temp Green Polyester Tape (PET Masking) – Up to 204°C / 400°F
Leader Masking Green Polyester Tape (also known as Green PET Tape) is the industry standard for general-purpose high-temperature masking.
Combined with a durable PET carrier and a specially formulated Silicone Adhesive, our tape bonds firmly to difficult surfaces (like metal, plastic, and glass) but peels off in one piece after the baking cycle. It is the perfect partner for our Silicone Plugs and Caps.

Description
Product Overview
If you are in the Powder Coating, E-Coating, or Anodizing industry, you know the pain of cheap tape: it melts, breaks, or leaves a nasty sticky residue that takes hours to clean off.
Leader Masking High Temp Green Tape is engineered to solve these problems.
Combined with a strong PET carrier and a specially formulated Silicone Adhesive, our tape bonds firmly to difficult surfaces (like metal, plastic, and glass) but peels off in one piece after the baking cycle. It is the perfect partner for our Silicone Plugs and Caps.
Key Features & Benefits
-
🚫 Zero Residue Guarantee: The premium silicone adhesive does not transfer to the part, even after baking at 204°C (400°F). Say goodbye to extra cleaning labor.
-
🔥 Extreme Heat Resistance: Rated for continuous use up to 204°C (400°F) and intermittent spikes up to 220°C (425°F). Ideally suited for powder coating curing ovens.
-
💪 Strong & Flexible: The 2-mil polyester backing is thin enough to create sharp paint lines but strong enough (tensile strength) not to break during removal.
-
🧪 Chemical Resistance: Resists shrinking and curling in Anodizing acid baths and E-Coating immersion tanks.
-
✂️ Precision Slitting: We can slit the tape to ANY width you need (from 2mm to 500mm) with 0.1mm tolerance.
