FAQ
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.
