Parylene’s effectiveness as a barrier coating stems from a unique synergy between its vapor deposition process and its inherent material chemistry. The vapor deposition ensures pinhole-free, conformal coatings, even on intricate geometries.  Combined with Parylene’s dense molecular structure and chemical inertness, this uniform layer creates a robust barrier, shielding electronics from moisture, chemicals and environmental threats.

Example Applications: 

• Smartphones
• Tablets
• Laptops
• Power tools
• Cameras
• Power Supplies

Parylene coatings possess inherent dielectric properties that are highly useful for insulating electronic components and circuits, especially in applications where electrical isolation is critical, such as in miniaturized electronics. Applying parylene coatings onto printed circuit boards and components ensures that current travels only along designated pathways within the circuit.

Example Applications: 

• Printed Circuit Boards (PCBs)
• Sensors
• Capacitors
• Batteries
• Telecommunication devices
• Motor Drives and Inverters

Parylene coatings can reduce the coefficient of friction between moving components. In electronic devices with sliding or rotating parts, such as switches, connectors, or mechanical assemblies, the dry lubricity of parylene can help minimize frictional forces where precise control or synchronization of moving parts is required.

Example Applications:

• Robotics
• Piezoelectronics
• Locking Mechanisms
• Controller Buttons and Joysticks
• Slider Switches and Potentiometers

Biocompatibility is essential for engineers designing wearable consumer electronic devices like smartwatches and fitness trackers that come into direct contact with the skin for extended periods. Biocompatible and bioinert, parylene coatings are well-tolerated by the skin and do not elicit allergic responses or sensitivities, making them safe for prolonged wear.

Example Applications: 

• Smartwatches
• Fitness Trackers
• Virtual Reality (VR) Headsets
• Sleep Monitors
• Hearing Aids
