Ultrastatic ESC Coating System

A New Precision Ultrasonic Coating Technology


Ultrastatic ESC comparison pic web

Sono-Tek has partnered with one of the world’s leading electrostatic coating manufacturers in the world, Sames Kremlin, to develop an exciting new coating technology: Ultrastatic® Enhanced Spray Coating

This newly developed Ultrastatic® ESC option is available for special early release to research institutions.

The Ultrastatic® ESC system uses ultrasonic atomization in combination with electrostatics. The joining of these two long-established coating techniques has shown interesting results, often enhancing deposition and coating attributes.* Ultrastatic ESC is currently being offered as a research and development tool for laboratories and universities exploring new methods of thin film deposition.

*Results vary greatly and depend on substrate and liquid properties.

The Ultrastatic ESC option is easily configured with Sono-Tek XYZ motion systems for full custom coating solutions offering many features and benefits:

  • Programmable coordinated XYZ motion
  • Capable of very low flow rates
  • Self-cleaning, non-clogging ultrasonic nozzle
  • Break up of agglomerated particles due to ultrasonic nozzle vibrations

Sono-Tek ultrasonic nozzles operate by converting high frequency sound waves into mechanical vibrations, which atomize liquids into mathematically defined micron sized droplets. These droplets have a very tight drop distribution, and their size is dictated by the frequency at which the nozzle operates. Continuous vibrations of the nozzle disperse particles evenly in suspension during the coating process, creating homogeneous thin film layers of functional particles. For more information regarding the unique nature of ultrasonic spray and how ultrasonic nozzles work, visit http://www.sono-tek.com/how-ultrasonic-nozzles-work/.

Patented low velocity air shaping systems entrain the atomized spray into precisely defined patterns. The type of air shaping system used depends upon application requirements. AccuMist and Vortex air shaping systems are most suitable for Ultrastatic ESD applications.

Sono-Tek’s ExactaCoat and FlexiCoat systems are the perfect full coating solutions for Ultrastatic® ESD coating processes.

Our in-house laboratory facilities enable customers to prove atomization and explore process enhancement with the assistance of our ultrasonic coating experts.
