high-quality roll-based slot-die coating machine


The FOM arcRC has been designed to replicate industrial roll-based coating in a smaller, lab-friendly format, by integrating industry-grade components and a user-friendly interface.

FOM arcRC provides a seamless, accelerated user workflow and excellent control for coating various functional materials. It is an ideal solution for users aiming to bridge the gap between lab-scale research and technology demonstration, emphasizing control of sheer and gravity effects via variable slot-die angles and positions around the coating roll.

Compact lab-scale slot-die coating system

Originally designed for organic photovoltaics (OPV) and light-emitting electrochemical cell research (LEC), the FOM arcRC is ideal for researchers who wish to work with flexible substrates on a platform that is closer to a pilot-scale production line.

From lab-to-fab concept

The arcRC is designed as a versatile research tool with an extra-large printing area capacity, yet compact enough that you can fit it inside a glove box. From the advent of perovskite-based photovoltaics, the technology readiness of lithium-ion batteries, to the development of any disruptive product idea that exploits the numerous advantages of thin-film technologies, the arcRC will boost any research targets from laboratory small-sized flexible devices to production relevant scales. Post-deposition treatments units such as drying/annealing and docking modules can the stand-alone FOM arcRC tool into a roll-to-roll unit. The FOM arcRC tool is well equipped for boosting the technology readiness level of your research, and demonstrating proof of concepts from lab to fab.
