Advantages of ultrasonically applied coatings:

  • reduction of material consumption and loss during spraying by up to 80%
  • high control of spray pattern for reliable, consistent results
  • ability to provide very low flow rates
  • controllable droplet size
  • z-axis movement allows optimisation of the width of the sprayed spray pattern
