NTTF, located close to Bonn, Germany, is specialised in plasma coatings for medical devices and other high-tech coatings. The cardient® HydroX coating is applied using a reactive gas-phase plasma and is used a s a"top" coat on other coatings to make them hydrophilic or hydrophobic.
It is made of an amorphous carbon coating which has been doped with various precursors in order to adjust the contact angle with water or oil for example. In addition the doping can be modified to provide anchor points for molecules such as drugs.
Application areas are microfluidic systems and urological adn vascular catheters.
Materials that can be coated are polymer materials, metals, ceramics and highly temperature sensitive materials.
