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 is engineered for demanding powder coating and industrial finishing processes. Featuring a durable PET (polyester) or Polyimide (Kapton) backing coated with a premium heat-resistant silicone adhesive, it withstands extreme temperatures up to 260°C (500°F) while maintaining strong adhesion and flexibility. The tape ensures clean removal without residue after exposure to curing ovens, even under prolonged heat. Its chemical resistance prevents solvent bleed-through, enabling sharp paint lines and protecting substrates during powder coating, anodizing, or e-coating operations.
Exceptional Heat Resistance: Stable up to 260°C, preventing shrinkage, curling, or adhesive degradation during powder coating curing cycles and autoclave processes.
Precision and Clean Removal: Silicone adhesive bonds firmly to metals, plastics, and painted surfaces but peels off easily in one piece without tearing or leaving residue, minimizing costly rework.
Chemical and Solvent Resistance: Protects against powders, acids, and alkalis used in surface treatment, ensuring no edge bleed or tape failure in aggressive environments.
Conformability and Durability: Flexible backing adapts to complex curves (e.g., automotive parts, machinery) without lifting, even in humid or abrasive environments.
Superior Dielectric Properties: Excellent electrical insulation makes it ideal for masking sensitive electronic components during high-heat soldering and manufacturing.
Powder Coating Masking: Shields threads, holes, and critical areas on automotive wheels, aerospace components, and metal furniture during high-temperature curing.
Surface Treatment Processes: Ideal for masking in anodizing, electroplating, or chemical milling baths, where chemical resistance is critical.
Industrial and Automotive Finishing: Used for sharp paint lines on machinery, appliances, and RV parts, withstanding baking ovens up to 260°C.
Electronics and Appliances: Protects sensitive components during PCB wave soldering, SMT reflow, or appliance coating, thanks to dielectric properties and heat resilience.
Backing Materials: Choose between PET (Polyester) for general high-temp applications (up to 220°C) or Polyimide (Kapton) for extreme heat and electrical insulation (up to 260°C+).
Custom Colors: Available in Translucent Green, Amber, Clear, or custom Pantone colors for easy process color-coding in your facility.
Precision Slitting & Die-Cutting: Custom widths from 3mm to 500mm, and complex die-cut shapes for automated PCB and component masking.
Jumbo Rolls & Packaging: Available in master rolls for converters, with custom core sizes (26mm, 32mm, 76mm) and comprehensive private-label packaging services.

Our AdvantagesOur Advantages
A Strong and Established Tape Manufacturer
Both utilize a heat-resistant silicone adhesive for clean removal. PET tape (often green, blue, or clear) is highly cost-effective and withstands temperatures up to 220°C, making it ideal for powder coating and general automotive baking. Polyimide (Kapton) tape (amber/translucent brown) offers extreme thermal stability up to 260°C+ and superior electrical insulation, making it the standard for PCB wave soldering, SMT, and aerospace applications.
No. Our 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 high-temp tape peels off cleanly in one piece without tearing or leaving any sticky residue, eliminating post-process cleaning.
Yes. The dense PET/Polyimide 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 milling, 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 and die-cutting machines to provide custom narrow widths (down to 3mm) and complex shapes, ideal for precise PCB masking and automated manufacturing lines.
