FAQ
Tape Selection What are the recommended tapes for high-temperature powder coating masking vs. transformer insulation bundling?
Industrial applications require specific pressure-sensitive tapes designed either for temporary thermal surface protection (masking) or permanent electrical dielectric strength (insulation):
| Application Scenario | Recommended Tape Grade | Technical Specs & Performance Metrics |
|---|---|---|
| 1. High-Temp Powder Coating Masking | Green Polyester (PET) Tape / Silicone Adhesive | 200°C (392°F) resistance for 30 min. Clean single-piece removal without slivering, edge bleeding, or ghosting residue on electro-coated substrates. |
| 2. Extreme Thermal Spray / Anodizing Masking | Amber Polyimide Tape (HL-2535/2550 Series) | 260°C – 300°C extreme heat tolerance with silicone pressure-sensitive adhesive. Chemical resistant against acid anodizing baths and plasma spray. |
| 3. Transformer Coil Bundling & Margin Insulation | Woven Glass Cloth Tape (HL-140175) / Polyimide Tape | Class H (180°C+) insulation grade with high mechanical tensile strength (>180 N/25mm) and dielectric breakdown voltage (>3kV) for oil-immersed & dry-type transformers. |

Dielectric & Residue SOP How do you ensure zero adhesive residue during powder coating peel and high dielectric safety for electrical coils?
Residue Prevention & Dielectric Testing: For powder coating, residue is eliminated by applying fully cross-linked, high-grade silicone adhesives on thermal-stabilized PET backing. This ensures clean hot peeling immediately after baking without leaving silicone transfer on metal threads. For transformer manufacturing, our Glass Cloth and Polyimide insulation tapes undergo 100% dielectric withstand testing and solvent compatibility checks to prevent varnish degradation during coil impregnation cycles.
