PET and PC Screen Printing Ink for Membrane Switches
Manufacturing high-quality membrane switches and graphic overlays for electronic devices requires highly specialized ink. The printed layer must not only bond permanently to PET and PC films but also withstand rigorous mechanical stress. Two of the biggest challenges in this industry are ink cracking during the button embossing process and delamination when applying double-sided backing adhesives.
Our 9800 Ink Series is engineered specifically to resolve these issues. Offering exceptional flexibility and superior tape compatibility, it ensures a flawless finish and long-lasting durability for electronic control panels.
Technical Specifications: 9800 Ink Series
Available in both standard and Halogen-Free versions to meet global electronics manufacturing standards, this ink provides versatility for either 1-component or 2-component applications.
- PET-9800: Standard Version
- HF-PET-9800: Halogen-Free (HF) Version for stringent eco-electronics
- Excellent Embossing Property: High flexibility prevents ink cracking during the button forming/embossing process.
- Superior Tape Compatibility: Excellent adhesion with double-sided mounting tapes (e.g., 3M) without chemical reaction or delamination.
- Outstanding base adhesion to both treated PET and PC substrates.
Frequently Asked Questions
Will this ink crack during the button embossing process?
No. The 9800 series is formulated with high-flexibility resins. It features an excellent embossing property, allowing the printed PET/PC film to undergo deep drawing and tactile button pressing without the ink cracking or flaking off.
Is it compatible with standard double-sided adhesive tapes?
Yes. A major advantage of this ink is its exceptional adhesive tape compatibility. It creates a stable chemical barrier that allows industrial double-sided tapes to bond securely to the printed surface without causing delamination over time.
