All our inks are metalized using a fast and simple cold plasma process.


We introduce our newest product family - OTech Platinum. Platinum is widely used in automotive, chemical, and other industries as a catalyst, a coating, or a sensor. To cover different needs, we offer three platinum ink formulations that differ by the form into which they metalize. Like all of our inks, platinum inks can be applied on flat or 3D surfaces and deposited by inkjet, aerosol spray, and other printing methods.
