Protect circuit boards from environmental risks

Safeguard Your PCBs from Moisture, Vibration, Temperature Extremes and Dust

Today’s electronics are exposed to a host of environmental risk factors:

  • Temperature extremes, both high and low
  • Excess moisture in the air or condensation
  • Dust and particles: Even minute amounts of dust can infiltrate seams and lead to electrical failures
  • Vibration, especially electronics used in vehicles, avionics or other equipment

With NuSil silicone conformal coatings, electronics manufacturers can help ensure that their circuit boards provide the operating life required for the digital devices that use them, regardless of the application.

One PCB Manufacturer Got Exactly What It Needed

A high-tech electronics manufacturer needed to replace an existing silicone coating when it became completely unavailable. NuSil silicone conformal coatings turned out to be exactly what the company needed—and more.

Our silicone conformal coatings were able to run in the company’s coating equipment with no modification. In addition, the electronics manufacturer noted added benefits from the NuSil coatings:

  • Better adhesion to the board, especially around the solder joints
  • No need to prime the PCB prior to coating, reducing processing time and costs

Find the Right Silicone Conformal Coatings for Your Application

NuSil silicone conformal coatings have a number of characteristics important to electronics manufacturers:

  • Cure at room temperature within 24 hours
  • Non-corrosive oxime cure system
  • Electrically insulating
  • Low viscosity ideal for use in spray- or dip-coating systems
