|
| Main Use |
| As a pressure-sensitive adhesive, traditional high-temperature tape coating equipment can be used to coat PET, aluminum foil and other substrates to produce pressure-sensitive adhesive tapes with special properties. It has good high temperature resistance and chemical resistance, and can also be used for printing. Shielding during the circuit board electroplating process, SMT process, FPC, PCB board, sandblasting, painting, high temperature baking, gold plating or the parts that need to be protected during the electroplating process, as well as insulation wrapping and fixing of electronic, electrical and other products. |
