Sono-Tek (NASDAQ:SOTK) is a designer and manufacturer of precision ultrasonic spray coating systems, acoustic atomization nozzles and related OEM modules. Founded in 1982 as a spin-off from research conducted at Stony Brook University, the company pioneered the use of high-frequency acoustic energy to produce uniform liquid coatings and fine mists. Its patented ultrasonic nozzle technology enables exact control of droplet size and coating thickness, making it well suited for applications that require precision and consistency.
The company’s products are used across a broad range of industries, including packaging, medical devices, electronics, agriculture and automotive. In pharmaceutical and biotechnology settings, Sono-Tek systems are employed for spray-drying of active ingredients and for coating tablets. In the electronics arena, its nozzles deposit uniform dielectric or conductive materials onto circuit boards and displays. Sono-Tek also serves manufacturers of laminates, wood products and specialty films by applying adhesives, release agents and other chemical coatings with minimal overspray and waste.
Headquartered in Milton, New York, Sono-Tek operates a global sales and support network with regional offices and distributors in North America, Europe and Asia. The company maintains an R&D center at its U.S. headquarters, where it collaborates with OEM partners and research institutions to develop customized coating solutions. Sono-Tek’s focus on sustainable manufacturing stems from its ultrasonic approach, which reduces material consumption and environmental impact compared to conventional spray methods.
Under the leadership of founder and CEO Norman C. Lapointe, Sono-Tek has grown its product portfolio to include fully automated spray systems, multi-nozzle arrays and turnkey production lines. The company continues to pursue product innovation and market expansion, leveraging its intellectual property and engineering expertise to address emerging coating challenges in established and new industry segments.
