PriElex® Jettable Polymeric Materials

PriElex® is envisioned as a new suite of functional inks for inkjet printing of electronic devices. PriElex® polymeric inks are designed and optimized for jetting and are suitable for maskless lithography, rapid prototyping, and clean, non-contact printing. Material formulations are tailored for critical inkjet properties such as viscosity, evaporation rate, and surface tension, and exhibit improved latency, firing stability, and resolution over standard resist formulations.

MicroChem currently offers XP PriElex® SU-8 1.0, an inkjettable SU-8 ink, adding to the developer's toolbox of printable materials available for the fabrication of single or multi-layer structures. Ink development was performed around the FUJIFILM Dimatix DMP printer, one of the most common R&D and prototyping inkjet tools.

Other PriElex® functional inks are envisioned, with some currently under development. If you'd like to learn more about our PriElex® development program, or have a specific need you'd like us to consider, you may reach us at
