Thin Film Functional Glass Coatings

Functional Coatings

Uniform dispersion of functional nanoparticles for electrically active coatings

Ultrasonic spray has significant advantages over other coating methods for functional glass coatings such as Transparent Conductive Oxide coatings. Ultrasonic nozzles are uniquely suited to spraying suspensions with electrically active particles, dispersing them particles in suspension uniformly to produce excellent electrical properties.

Sono-Tek coating systems are used to spray a wide range of functional coatings onto different sizes of types of glass, plastics, and metals, for a number of different applications:

  • Transparent Conductive Oxide coatings
  • Photoresist coatings
  • Electrochromic coatings
  • CNT or Nanowire coatings
  • Anti-reflection (TiO2, SiO2) coatings

Uniform dispersion of particles results in larger active surface area, creating greater electrical performance with thinner layers. High uniformity across large areas at a fraction of the cost of CVD and other conventional processes. Highly controllable spray enables selective area coating processes not possible with other coating methods.
