Blue PET High Temperature Tape – 155℃ Masking for Electroplating & Coating

The Blue PET High Temperature Tape is a premium masking solution specifically engineered for electroplating, anodizing, and industrial coating applications where reliable high-temperature performance and chemical resistance are essential. Constructed with a distinctive blue PET film backing and coated with a high-performance silicone adhesive, this tape delivers exceptional thermal stability at continuous operating temperatures up to 155℃. The vibrant blue color provides excellent visual contrast against metal substrates, anodized aluminum, and PCB surfaces, enabling operators to quickly verify mask placement and reduce application errors in fast-paced production environments. With a dielectric breakdown voltage exceeding 5kV, it offers dependable electrical insulation for electronic component protection. The tape exhibits outstanding chemical resistance to acidic and alkaline baths commonly used in electroplating and anodizing processes. Designed for plating shops, PCB manufacturers, and industrial coaters, this blue polyester tape removes cleanly after processing, leaving zero adhesive residue and ensuring consistent, high-quality results.

• Distinctive Blue Color for Enhanced Visibility: The vibrant blue backing provides superior visual contrast against aluminum, copper, steel, and green PCB substrates, enabling fast inspection, precise alignment, and reduced masking errors on busy production lines.
• 155℃ Continuous Temperature Resistance: Maintains strong adhesion and dimensional stability during electroplating bath cycles, anodizing processes, powder coating curing, and wave soldering without shrinkage or edge lifting.
• Outstanding Chemical Resistance: Engineered to withstand prolonged exposure to acidic and alkaline plating solutions, anodizing electrolytes, flux, solvents, and cleaning agents without degradation or adhesive breakdown.
• Superior Electrical Insulation: Dielectric breakdown voltage exceeds 5kV, providing reliable protection for sensitive electronic components and PCB contacts during soldering and high-voltage testing.
• Conformable with High Elongation: Elongation exceeds 40% , allowing the tape to conform smoothly to curved surfaces, irregular shapes, and complex geometries while maintaining a secure edge seal against chemical ingress.

• Electroplating Masking: Protects designated areas, threads, and contact points from metal deposition during copper, nickel, chrome, and zinc electroplating processes. Resists chemical attack and removes cleanly after plating.
• Anodizing Protection: Masks surfaces that must remain unanodized on aluminum parts, including threaded holes, grounding points, and mating surfaces. Withstands the acidic anodizing bath environment.
• PCB Wave Soldering Masking: Safeguards gold finger contacts, edge connectors, and test points from solder splash and flux contamination during high-temperature lead-free wave soldering.
• Powder Coating Curing Ovens: Protects threaded inserts, studs, and bearing surfaces that must remain coating-free during 150℃–155℃ powder coat curing cycles.
• Conformal Coating Masking: Creates sharp, defined boundaries for acrylic, silicone, and urethane conformal coatings applied to PCB assemblies after SMT placement.
• Chemical Milling & Etching: Serves as a chemical-resistant maskant for selective metal etching and chemical milling operations in aerospace and precision manufacturing.

Product: Blue PET High Temperature Tape – 155℃ Masking for Electroplating & Coating

Q: Can this tape withstand acidic electroplating baths?

A: Yes. The PET backing and silicone adhesive exhibit excellent resistance to acidic plating solutions (copper sulfate, nickel sulfamate, chromic acid) and alkaline cleaners. The tape maintains its integrity and edge seal throughout typical plating cycle durations.

Q: Is this tape suitable for masking prior to powder coating?

A: Yes. The tape withstands powder coating cure cycles up to 155℃ and removes cleanly from metal surfaces after the part has cooled, leaving sharp coating lines and no adhesive residue.

Q: Can this tape be used in wave soldering applications?

A: Absolutely. The 155℃ continuous rating and >5kV dielectric strength make it an excellent choice for protecting PCB gold fingers and connectors during lead-free wave soldering processes.

Q: What is the recommended storage condition and shelf life?

A: Store in original packaging at 23℃ (73℉) and 65% relative humidity. Under these conditions, the tape maintains optimal performance for 6 months from date of shipment. Avoid exposure to direct sunlight and high humidity environments.

Q: Is this tape compatible with automated dispensing equipment?

A: Yes. The consistent thickness and controlled unwind properties make it suitable for most automatic tape dispensers and laminating systems used in high-volume electronics and plating operations.
