Industry

Renewable Energies (Wind and Solar)

Renewable energy infrastructures are often located in hostile environments (sea, desert) where maintenance is extremely expensive.

• Offshore wind: Parylene is used to protect nacelle sensors (anemometers, thermometers) and control units from highly corrosive salt spray.
• Solar photovoltaic: It protects the inverter control circuits from moisture and thermal cycling.
• Advantage: Its lifespan of more than 25 years corresponds to the life cycles of these installations, whereas conventional varnishes would degrade in a few years.

Water & Energy Industry (Oil & Gas)

In this sector, equipment is subject to extreme pressures and aggressive chemicals (H2S, acids).

• Downhole sensors: Pressure and temperature sensors used in oil or geothermal drilling are parylene-coated to resist acid corrosion.
• Smart water meters: The circuit boards of communicating water meters (IoT) are protected to prevent failure due to condensation or possible leaks.
• Advantage: Parylene is one of the few polymers that can withstand prolonged immersion in hydrocarbons and organic solvents without swelling or peeling.

Consumer Electronics and IoT (Wearables)

For the objects we wear every day, parylene offers invisible protection.

• Hearing aids and smartwatches: Parylene protects miniature electronics from human sweat (which is very corrosive due to acidity and salts) and daily humidity.
• Smartphones (Internal Components): It is used to waterproof certain micro-components such as MEMS microphones without blocking their mechanical movement, thanks to its extreme thinness.
• Advantage: Unlike resins, parylene adds virtually no weight and does not change the design or feel of the product.

Protection of industrial parts against corrosion

Together with HEF, we have developed advanced thin-film coating solutions for industrial components exposed to harsh environments. In demanding applications where corrosion, wear, and chemical aggression are critical concerns, long-term surface protection is essential. This challenge is addressed through a combination of Parylene and other CVD-based coatings, providing a conformal, ultra-thin, and highly resistant barrier on complex geometries. The coating protects mechanical parts from moisture, corrosive agents, and while maintaining tight dimensional tolerances. As a result, treated components deliver extended service life and reliable performance in the most demanding industrial environments.
