About COAT-X
COAT-X was founded in 2016 in La Chaux-de-Fonds (Switzerland) and is a privately managed company for ultra-thin barrier coatings. The company offers Parylene coatings as a job-coating service, manufactures automated Parylene deposition systems for applications ranging from research and development to industrial batch production, and distributes qualified Parylene C, F-VT4 and F-AF4 dimers as well as consumables and spare parts. In addition, COAT-X is an independent service partner for Picosun ALD R-Series and P-Series systems from Applied Materials and offers atomic layer deposition with ceramic thin films of Al₂O₃, TiO₂ and HfO₂. The coatings protect sensitive electronics (PCB, PCBA), medical technology implants and high-quality components in demanding environments. COAT-X is part of the PLASMALEX group (together with Europlasma, CPI and SPOOLEX) and serves customers among others in medical technology, electronics, semiconductor advanced packaging, industry and energy. Languages: German, French, English.
