EPRIMA® AL-X6 is a thermally curable insulating coating that is based on a fluorinated polymer. The surface wettability of the highly transparent dielectric coating can be controlled by exposure to UV, enabling accurate ink-wettable alignment guides to be created in the coating when printing conductive inkjet inks such as those containing copper or silver. Without Al-X6, conductive inkjet lines can print down to 30-40 microns. With AL-X6, discrete conductive inkjet lines of 15 microns (on 20-micron separation) have been achieved without
spreading or bulging.

The degree of wettability is highly controllable, enabling biochips where a varying gradient of wettability draws liquids through the chip. AL-X6 is highly transparent compared to polyimide, and requires lower curing temperatures. Heat loads to the other biochip materials can therefore be much lower. AL-X6 is extremely flexible. Its flexibility and mechanical properties provide
application advantages over epoxy.

The naturally hydrophobic surface becomes wettable when exposed to common i-Line 365nm UV. This is much less expensive than existing methods of wettability patterning, which require UV with a λ (lambda) of less than 300nm and special optical components. No additional equipment is required to use AL-X6.

The coating already has been tried successfully as a dielectric material for OTFT (Organic Thin-Film Transistors) and as a pattern-assist material for metal inks. Manufacturing processes using AL-X6 take place at lower temperatures than polyimide — AL-X6 cures at 150°C, and at even lower temperatures and more
quickly if UV is used. It is thermally resistant to ~200°C, offers excellent resistance and planarizing abilities.

便益情報の要約 (Benefits Summary)

EPRIMA® AL-X6 provides a fluorinated polymer coating suitable for use as a dielectric and wettable pattern-assist material.

It offers excellent planarization for electronic and semiconductor applications. o Transparency: Transmittance is 99% at 400nm – visible light lies between 380nm and 700nm, so EPRIMA® AL-X6 is suitable for optical applications.

The material offers low temperature curing, so heat load on substrates may be lessened.

Unique functions can be added to the material, for example: UV exposure creates wettable areas on the surface of the material, enabling its use as an alignment aid for inkjet deposition of conductive inks. Lines of 15 microns have been achieved. A gradient exposure to UV can create biochips that draw liquid through the chip based on the gradient.

UV-curable EPRIMA® AL-X6 is also available.
