Automotive Coating Services


Developments in automotive technology have resulted in an increased use of computer and electronic systems in new vehicles. Because many of these components are critical to the car's proper operation, they must be protected from harmful vehicle fuels, like battery acid, oil and antifreeze.

Automotive conformal coatings are the best protection solution for these sensitive electronics. Coating protects the circuitry from damage without interfering with the circuit's operation. Diamond-MT offers several coating solutions applicable to the automotive industry.

Benefits of Automotive Conformal Coatings

Silicone and parylene are the best options on the market for automotive coating. The silicone is applied by dipping, brushing or spraying, and parylene uses chemical vapor-based deposition (CVD).

The advantages of silicone for automotive electronics include:

  • Impact and shock absorption
  • Thermal resistance more than 200 degrees Celsius
  • Moisture resistance
  • Flexible and soft
  • Adherence to printed circuit board (PCB) topography
  • Corrosion and ultraviolet (UV) light resistance
  • Quick curing time
  • Easy to rework

The benefits of automotive parylene coatings include:

  • Thinness for minimal mass addition to the component
  • Resilience
  • Moisture resistance
  • Dielectric protection against current fluctuations
  • Chemically inert for protection against salt, antifreeze, gasoline and brake fluid
  • Temperature resistance at minus 165 degrees Celsius without damage
  • Adherence to many materials and topographies
  • Bubble and pinhole-free surface
  • Optical clarity

Applications for Parylene Coating for Automotive Electronics

Automotive parylene coatings can be used for these vehicle electronics:

  • Emission controls
  • Fluid monitoring
  • Powertrain mechanics
  • Lighting
  • Sensors
  • Fuel systems
  • Digital displays
  • Fuel cells
  • Power controls for the windows, seats, mirrors, doors and sunroof
  • Tire pressure gaskets and seals
  • Antilock brakes control
  • Connectors
  • Monitoring systems
