LED Coating Services


Light-emitting diodes (LEDs) are an integral part of electronics and are used in many industries because they are energy-efficient and adaptable. While LED lights have a 100,000-hour lifespan, harmful environmental factors can impact their durability. Because so many devices rely on LEDs, they need protection to work correctly.

Conformal coatings offer effective protection and do not inhibit the LED's function while preventing contamination. At Diamond-MT, we have conformal coating for video displays, vehicle lighting and similar components that use LED lights.

Benefits of Parylene Coating for LEDs

There are three coatings that can be used on LEDs:

  • Parylene: Parylene is the best coating for moisture and solvent protection./li>
  • Acrylic Acrylic protects against moisture and can be formulated to be clear.
  • Silicone: Silicone has high heat requirements above 200 degrees Celsius and great moisture resistance because of its thickness.

Of these three options, parylene is the top choice. LEDs in a printed circuit board (PCB) for an outdoor application face tough operational and environmental conditions. Parylene is the conformal coating type that provides the best defense against ultraviolet (UV) light, moisture, chemicals and corrosion.

Other advantages of parylene for lighting include:

  • Uniform thickness across topography
  • Dielectric properties for protection against electrical currents
  • Resistance to temperature extremes
  • Lightweight for minimal mass added to the final product
  • Insulation properties
  • Pinhole-free protection
  • Optically clear to promote LED brightness

Applications of LED Parylene Coating

Many devices need LED conformal coating, including:

  • Electronic billboards
  • Scoreboards
  • Traffic signals
  • Transportation signage
  • Aviation lighting
  • Vehicle lighting
  • Marine lighting
  • Outdoor illumination
  • Commercial refrigeration
  • Video displays
