THE EUROPEAN SPECIALIST AND LEADER IN PARYLENE COATING A Swiss company created in 1979 offering a technological solution to a demand arising from the highly demanding watch industry, Comelec has grown its reputation over the years thanks to our expertise and the high quality of our services. By focusing all our resources and skill on the development and use of Parylene coating, we have become the European leader in the field. Seeking to better meet the specific needs of an extremely extensive range of applications for Parylene, we continue to expand our services based on a spirit of...

PARYLENE FILM TECHNICAL PROPERTIES : the process of vacuum deposition at room temperature endows this coating with unparalleled characteristics. It is free of any internal stress. Due to its extreme power of penetration, it conforms perfectly to even the most complex-shaped objects with a constant thickness ( perfect conformability ). Its thickness can be easily adjusted in a range of 50 nm to more than 100 µm. Its significant physicochemical inertia and the continuity of film, even in minimal thicknesses (  less than 100 nm on Wafer Si  leads to it being used primarily as an insulating...
