Parylene surface coating system P120D

automaticmedical

Parylene is the short designation of the polymer group of poly(para-xylylenes). The polymers consist of different substituted para-xylylenes. The original basis for coating are dimers. This is a molecular compound consisting of two identical sub-units, the so-called monomers. Parylene coatings offer a large number of benefits. Parylenes... are completely conformal, i.e. they adapt even to complex substrate contours such as sharp edges, bore holes or blind holes are pinhole-free already from coat thicknesses of approx. 0.5 µm are chemically insoluble and resistant against a large number of chemicals have very good barrier properties against moisture and chemicals have a high dielectric strength have dry lubricating properties (low coefficient of friction) are hydrophobic: wetting angle for H2O between 92° and 98° are transparent between 90 and 96 % in the visible wavelength range (depending on type) are biocompatible: parylenes of the types C and N can be separated which can be certified to USP Class VI, ISO 10993 and FDA. Coating substance Parylene N, C, D, F-VT4 Possible coat thicknesses 0.05 to 50 micrometers Dimensions Width approx. 2200 mm Depth approx. 2700 mm Height approx. 1600 mm Pyrolysis 4 kW / max 850 °C Chamber Diameter: 500 mm Length: 610mm
