PARYLENE COATING

Parylene is a trade name for polymers vaporized on the surface of objects to protect against moisture and produces a diaelectric barrier. It creates an excellent moisture barrier and is used to cover PCBs, medical devices and in many other applications. The coating created by Parylene has Bio-Medical properties and is used to coat: stents, pacemakers, defibrillators and other devices permanently implanted in the body. Parylene C applied to the PCB shows very good adhesion to all components installed on it.

Features and Benefits:

• A hydrophobic chemical resistant coating with good barrier properties for inorganic and organic carriers of acids, alkalis, gases and water vapor
• Biostable coating
• The coating is applied without temperature loading of the substrate because the coating takes place at room temperature in a vacuum
• Highly corrosion resistant
• Completely homogeneous surface
• Stable to oxidation up to 350 ° C
• Low internal stress
• Low coefficient of friction
• Very low gas permeability

Typical  applications:

• Hydrophobic coating (moisture barriers, for example for biomedical hoses)
• Barrier layers (e.g., filter, membranes, valves)
• Microwave electronics
• Implanted medical devices
• Sensors in difficult conditions (e.g. car fuel / air sensors)
• Electronics for space and military applications
• Corrosion protection of metal surfaces
• Strengthening micro structures
• Protect plastic, rubber, etc. under harmful environmental conditions
• Reducing friction, for example, for guide catheters, acupuncture needles and in micro electromechanical systems.
