OrelTech GmbH is a Berlin-based company that produces and distributes precious metal inks for metallization by means of ink-jet printing, aerosol spray deposition and dip dying. OrelTech pioneered a novel platform metallization technology that enables the deposition of conductive, flexible and even transparent metal layers onto a variety of surfaces, including temperature-sensitive plastics, fabrics, paper, composites, and active organic materials. The proprietary technology comprises of novel nanoparticle-free inks and a plasma-based curing process. This combination offers many advantages for the production of printed metal electrodes (including OLEDs) with regards to functionality, cost, material and energy economy, waste avoidance and worker safety.
Two of the company’s specialties are the world’s first particle-free gold and platinum inks which allow the deposition of thinner, more flexible and more conductive layers. Besides gold and platinum, the company offers silver and palladium particle-free inks.
