NTTF, located close to Bonn, Germany, is specialised in plasma coatings for medical devices and other high-tech coatings. In addition to the carbon coatings NTTF offers its customers also Parylene coatings.

The Polymer Para-Xylylen, in short Parylene, is applied in its gaseous phase in a vacuum and is completely porefree. Almost every substrate material e.g. plastics, ceramics, metals and alloys, glass and paper can be coated with Parylene. The Parylene coating process enables to evenly coat tricky surface and structures such as sharp edges, undercuts and small gaps that cannot be coated by using liquid based processes. In addition to this, in one operation process coating thicknesses from 0,1 to 50µm can be applied.

The application areas are very diverse: Parylene is used in medical, automotive and aerospace industry. Moreover, Parylene is excellently suited for the coating of electronic devices like PCBs as well as for corrosion protection of for instance magnets.

Characteristics of Parylene:

• good mechnical and very good electric characteristics,
• transparent (depending on thickness of coating),
• excellent protection against corrosion,
• lubricious surface,
• FDA-approved bio-material,
• chemically inert as well as acid and solvent proof,
• temperatur stable,
• excellent barrier against water.
