High Temperature Masking Tape /
High temperature masking tape is designed to withstand high temperatures, often up to 260°C (500°F), making it suitable for use in extreme conditions like powder coating or automotive painting. Suitable for use in multiple industries such as electronics, automotive, aerospace, and painting.
Backed by Jiangsu Gelly Adhesive Material Technology Co., Ltd and our 30 years of special tape expertise, our High Temperature Masking Tape (Light Green / Mint Green PET Series) is an elite shielding solution engineered for extreme thermal environments. Combining a premium light green PET (Polyester) film backing with a specialized heat-resistant silicone adhesive, this tape reliably withstands temperatures up to 260°C (500°F). The soft light green color provides a distinct, gentle visual contrast against dark metals and standard dark green tapes, making it the preferred choice for specific process color-coding, electronics manufacturing, and delicate powder coating applications, guaranteeing clean, residue-free removal.
Extreme Heat Resistance (Up to 260°C): Specially formulated to survive extreme conditions like powder coating curing ovens, autoclave cycles, and automotive paint baking without melting, shrinking, or degrading.
Distinct Light Green Visual Contrast: The light green / mint green color allows facility managers to easily differentiate this tape from standard dark green tapes, designating specific curing stages, delicate surface masking, or custom client color-coding requirements.
Superior Chemical & Solvent Resistance: The dense PET backing and silicone adhesive system are highly resistant to harsh solvents, acids, alkalis, and paint thinners, ensuring structural integrity in aggressive environments.
Zero Residue Clean Removal: Provides excellent grip on metals, glass, and composites, but is engineered to peel off easily in one piece after heat exposure, leaving absolutely zero sticky residue behind.
High Tensile Strength & No Tearing: The robust PET film backing prevents the tape from tearing or breaking during removal, minimizing surface damage and eliminating costly post-process cleaning.
Process Color-Coding: Widely used to designate specific mid-to-high temperature curing stages or to mask delicate components where a softer visual indicator is required compared to standard dark green.
Powder Coating & Industrial Ovens: Effectively masks off threaded holes, grounding points, and contact surfaces during high-temperature powder coating and curing processes.
Electronics & PCB Manufacturing: Used for masking components during wave soldering, SMT reflow, and high-heat electronic assembly where custom color identification is mandated by the manufacturer.
Automotive Painting & Baking: Protects trim, glass, and sensitive electronics during spray painting and high-heat paint booth bake cycles.

Our AdvantagesOur Advantages
A Strong and Established Tape Manufacturer
In complex manufacturing facilities, color-coding is essential. Light Green (Mint Green) PET tape is frequently used to differentiate specific mid-to-high temperature curing stages from standard dark green tapes. It provides a softer visual contrast that is easily identifiable by quality control inspectors, preventing operators from using the wrong temperature grade for delicate components.
No. Our heat-resistant silicone adhesive system is specifically formulated to remain chemically stable under extreme thermal stress. Unlike rubber-based adhesives that melt and bake onto surfaces, our light green PET tape peels off cleanly in one piece without tearing or leaving any sticky residue, eliminating post-process cleaning.
Yes. The dense PET backing combined with the silicone adhesive provides outstanding resistance to harsh acids, alkalis, and plating solutions. It is widely used to mask off threaded holes and contact points during chemical etching, electroplating, and anodizing baths without degrading.
Absolutely. As a direct manufacturer with 30 years of experience, we supply standard jumbo rolls for tape converters and offer comprehensive OEM/private-label services. We utilize advanced high-speed slitting machines to provide custom narrow widths starting from 3mm, ideal for precise PCB masking and automated manufacturing lines.
