Protect sensitive electronics at the molecular level—these ultra-thin, ultra-conformal coatings cover every inch of your components for applications where failure isn’t an option. They’ve even been trusted on satellites and medical devices. Use them to insulate current, prevent arcs and short circuits, and shield against moisture, chemicals, and gases. They’re better insulators than epoxy, urethane, and silicone coatings. Deposited as vapor in a vacuum chamber, they’re 90% lighter than spray and dip coatings. That means they’ll keep your items lightweight and won’t damage complex geometries. These coatings meet ASTM E595, a standard used by NASA, so they produce almost no volatile emissions that could damage sensitive electronics, even in a vacuum.

Note: These coatings must be applied using special parylene deposition equipment.

Parylene C coatings are the most widely used. They contain chlorine, so they shield against moisture, chemicals, and corrosive gases better than Parylene N coatings. Plus, they’re stronger and quicker to apply.
