Parylene Coating

Parylene ist ein Polymer, das oft zur Beschichtung von Oberflächen verwendet wird. Alle Parylene-Beschichtungen werden durch einen Gasphasenprozess in einer Vakuumkammer bei Raumtemperatur erzeugt. Das Monomer kondensiert und polymerisiert auf der Oberfläche und formt eine gleichmäßige und konforme Schicht, die der Oberflächentopografie folgt. Das Monomer wird außerhalb der Beschichtungskammer erzeugt, daher wird die Kammer nicht geheizt. Die Beschichtung erfolgt bei Raumtemperatur.

Vorteile

  • Beständigkeit gegenüber Säuren und Laugen
  • Schützt vor Feuchtigkeit und Staub
  • USP Klasse VI biokompatibel
  • Exzellente thermische Stabilität bis zu 450°C
  • Exzellenter Korrossionsschutz
  • Parylene ist FDA zertifiziert
  • Parylene hat eine größere Abriebsfestigkeit und eine bessere Gleitfähigkeit als PTFE

PLASMA (PVD)

Mit Plasmabeschichtungen lässt sich ein breites Spektrum von Oberflächeneigenschaften realisieren, die unter anderem in folgenden Anwendungsfeldern zum Einsatz kommen:

Anwendungen

  • Verschleißschutz von Präzisionsteilen
  • Beschichtung von medizinischen Implantaten und chirurgischen Instrumenten mit biokompatiblen Kohlenstoffschichten
  • Erhöhung des Korrosion-Schutzes
    Reduktion von Reibungskräften; z.B. in Gleitlagern
  • Dekorative Schichten
  • Hydrophile oder hydrophobe Oberflächen

Bei der Herstellung von Schichten mit Hilfe von Plasmen verwenden wir verschiedene Verfahren:

  • Sputtern
  • PECVD (Plasma Enhanced Chemical Vapour Deposition)
  • HIPIMS (High-Power Impulse Magnetron Sputtering)

CVD Parylene Coating Machines

We have developed three different sizes of Parylene coating equipment to cover the different industrial applications. The smaller unit has a cylindrical vacuum chamber with a diameter of 40 cm and a height of 45 cm; see illustration. This is located on a rolling housing with dimensions of 90 x 95 x 70 cm (W x D x H). Inside the housing are the evaporator and reactor modules, as well as the powerful vacuum pump and the rotary drive for the coating material pick-up. At the front of the unit is a door through which the parylene raw material (dimer) can be easily introduced for process operation.

Due to the technology of the vacuum system developed at NTTF, the plant does not require an additional cooling unit, as is necessary in conventional machines for this coating technology, so that both maintenance costs and energy costs are significantly reduced.
