PCB Waterproofing Protection

PCB Waterproofing Protection

Aculon's PCB waterproofing protection solutions are designed to protect printed circuit boards (PCBs) from water and other liquids. Water and moisture can be a major problem for electronics devices, causing corrosion, short circuits, and other defects that can lead to product failure.

  • Aculon's waterproofing solutions are based on proprietary nanotechnology coatings that are applied to the surface of the PCBs. These coatings are extremely thin, measuring only a few nanometers in thickness, which means they do not add significant weight or bulk to the PCB.

  • The coatings are highly hydrophobic, which means they repel water and other liquids. This provides a barrier against moisture and helps to prevent corrosion and other damage to the PCB.

  • PCB Waterproofing Protection

    Aculon's PCB waterproofing protection solutions are also easy to apply and can be used with a variety of different substrates, including metals, plastics, and ceramics. They can be applied using a range of techniques, including spraying, dipping, and roll coating.



  • Improved Device Reliability Due To Protection Of PCBs From Water Damage
  • From Accidental Submersion (IPX-4), Immersion For 30 Minutes (IPX-7) To Prolonged Immersion (IPX-8)*
  • Reduced Product Returns Due To Device Failures
  • Reduced Cost As No Masking Required
  • Improved Yields As The Coating Enables Rework After Application
  • Can Be Applied Via Spray,Dip, Or Dispense, Eliminating Need For Costly Vacuum Equipment
  • Save Energy Compared To Vacuum Equipment
  • Improve Throughput As It Does Not Require Batch Production
