Depositing Uniform Glass Coatings by Ultrasonic Coating Technology

Siansonic ultrasonic spray coating system is used for depositing various functional coatings on glass such as hydrophilic and hydrophobic coatings, protective polymer, AR anti-reflection coatings, TCO transparent conductive oxide coatings, electrochromic layers, photoresist coatings, etc. Ultrasonic spray coating is regarded as an effective technology for preparation of thin film coating. Compared with the traditional air spray coating, ultrasonic spray coating has the advantages of precisely control of coating thickness, high uniformity, little overspray and splash resulting in much reduction of raw materials consumption. Ultrasonic coating systems are low cost hardware compared to CVD and sputtering equipment, significantly reducing the initial investment on manufacturing facilities, especially for coating on large-area glass.

Siansonic has almost 40 years of experience on applied ultrasonic technology and over 15 years of experience on ultrasonic spray coating. Siansonic can provide turn-key coating solutions for various types and specifications of glass including float glass, solar cell panel glass, display glass, lens, etc. Benchtop ultrasonic coating systems UC320, UC330, UC340,  industrial ultrasonic coating systems UC360c, automatic ultrasonic coating system PL360, PL600 can satisfy all requirements from R&D to volume production. For large area coatings, Siansonic ultrasonic nozzle array can theoretically coat the substrate with any width. For example, an array of 30 Widemist ultrasonic spray nozzles can coat a glass panel up to 3-4 meters in width.
