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.

We introduce you to our new line of products, OTech Coating Solutions: A line of products optimized for the deposition of metal coatings. Low curing temperature makes our products particularly useful for coating temperature-sensitive materials like plastics. Electroplating experts praise ORELTECH technology as particularly easy and simplified process suitable for the coating of small plastic parts in small and medium quantities.
OTech Coating Solutions can be deposited with aerosol spraying, slot die, dip dye coating, and other coating techniques. Read more about the use of OTech Coating Solutions in plating on plastics.
New solutions for functional metal coatings
ORELTECH technology opens up new possibilities in coating deposition and processing with energy-efficient plasma curing and unique formulation that permeates into complex structures and ensures better performance with less material used.


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.
Electroless deposition on plastics
Plasma treatment of OTech Coatings enables direct deposition of metals on plastic surfaces. The process does not rely on electrochemical baths, seed layers or chemical treatments for successful coverage of plastic surfaces.


OTech Silver Coating Solution
Silver is broadly utilized as a coating for its antibacterial, anti-corrosive, electrical, and many other properties. It is a material of choice when it comes to precious metals as it provides the best trade-off between functionality and price.
