Why Parylene

There are many methods for applying conformal coatings, including spray, dip or vacuum deposition and each has their strengths and weaknesses. Spray and dip coating processes are typically done with acrylics, silicone, and urethanes. These coating processes are relatively inexpensive and easy to apply, but those benefits are often realized at the expense of important material attributes, including superior corrosion and or chemical resistance, extreme coating conformability and thickness control, biocompatibility and very low moisture and gas permeability, among others. Following is a list of the many desirable material properties of Parylene conformal coatings, which are applied at room temperature in vacuum deposited chemical vapor deposition (CVP) processes.

• Highly Corrosion Resistant
• Low Dielectric
• Optically Transparent
• Provides Mechanical Strength
• Performs in Extreme Temperatures -200°C to +140°C
• Superior Solvent & Acid Resistance
• Biocompatible-Class VI Approved Plastic
• Truly Conformal – On All Surfaces Even Sharp Edges
• Superb Bacteria and Fungus Resistance
• Very Low Moisture & Gas Permeability
• Low Out-Gassing
• Low Coefficient of Friction
• Approved for Military & Aerospace Applications
• Salt Water & Mold Resistant
