Anti-fouling Coating for Electronics


Antifouling coating can protect electronic circuit/Microelectromechanical systems (MEMs) against moisture. The coating is done by vacuum vapour deposited without the presence of liquid/water. Thus, no damage will be caused to the electronics/MEMs due to direct contact with liquid. For gas sensing MEMs, the coating (water proof but gas permeable) can provide protection against the moisture of gas, increasing shell life substantially

Problem addressed

Electronics and MEMs are easily damaged when they come into contact with liquids. Traditional anti-fouling (hydrophobic) coating is coated by resin (liquids), so it cannot be applied to electronics and MEMS.

  • The new coating technology uses liquid-free vacuum method for vapour coating, which can provide anti-fouling protection for the electronics/MEMs without causing damages.
Key impact
  • Strengthening the protection and anti-fouling function of electronic products and MEMS, without causing any damages during the process.
  • Water proof and gas permeable
  • Can be widely applied on different materials
