OUR PRODUCTS

MADE IN GERMANY

ORELTECH’s unique metallization solutions come in two distinct product categories:

OTECH CONDUCTIVE INKS and OTECH COATING SOLUTIONS.

The choice of product depends on the application method: choose OTECH INKS for inkjet, aerosol jet, microdispensers, and other printing methods, or choose OTECH COATING SOLUTIONS for spray coating, slot die coating, dip dyeing, bath coating, rotating barrel and many others.

Currently available metals are silver, gold, platinum, and palladium. Other metals (e.g. iridium or copper) can be developed upon request.

All products are metalized by fast and simple plasma treatment. ORELTECH’s unique plasma curing process allows green, economical production without generating toxic waste. By using plasma, you can save up to 95% on electric energy!

To learn more about plasma curing, read our blog or contact us.

When you choose OTech products, you choose to optimize the use of precious metals in your product, lower your carbon footprint, and cut production costs.

OTech conductive inks have a unique, particle-free formulation that directly improves the printability of the inks without clogging printer nozzles. Our particle-free formulations are significantly more environmentally friendly than alternatives on the market. The resulting layers are high-performing regarding conductivity, flexibility, and stability and of the highest purity.

Better coverage with less material

Because of their liquid formulation, OTech Coating Solutions can permeate complex structures and are therefore suited for the deposition of active metal layers such as antibacterial silver on filters or catalytic platinum on powders.

Whatever the supporting substrate, OTech Coating Solutions provide an even coverage of complex structures like foams, meshes or powders at a minimal metal consumption.
