Sono-Tek (NASDAQ:SOTK) is a specialized equipment manufacturer that designs, develops and sells ultrasonic spray coating systems for precision fluid delivery. The company’s core technology uses high-frequency ultrasonic vibrations to generate fine, uniform droplets that can be applied to a broad range of substrates with minimal waste and high accuracy. This method enables precise control over coating thickness, distribution and material usage, making it well suited to applications requiring micro-scale deposition and tight process tolerances.
The company’s product portfolio includes bench-top research and development stations, pilot-scale units and full production systems. Sono-Tek also offers ultrasonic nozzles, flow controllers and integrated spray heads that can be customized to meet specific client requirements. Key application areas for these products span the electronics industry (including printed circuit board solder pastes and conformal coatings), pharmaceutical and biotechnology (such as microencapsulation and thin-film drug delivery), energy storage (battery electrode coatings) and emerging industries like solar-cell fabrication and advanced materials research.
Headquartered in Milton, New York, Sono-Tek supports a global customer base through direct sales and service offices in Europe and Asia. The company’s facilities include manufacturing, research laboratories and a technical applications center where prospective users can test formulations and optimize process parameters. Over the years, Sono-Tek has built a reputation for collaborating with academic institutions, contract research organizations and OEMs to develop bespoke coating solutions that address both established and emerging market needs.
Sono-Tek’s management team is led by President and CEO Robert Gershon, under whose guidance the company has continued to refine its ultrasonic spray technology and expand its reach into new industry verticals. Continuous investment in research and customer support has enabled Sono-Tek to maintain its position as a leading provider of precision spray coating equipment for sectors that demand exacting quality standards and efficient material usage.
