Sono-Tek Shipping Three Ultrasonic Coating Solutions to New Fuel Cell Industry Customers in China

MILTON, N.Y., November 8, 2018 – Sono-Tek Corporation (OTCQX: SOTK), the leading developer and manufacturer of ultrasonic coating systems, announced that it received orders from three new customers in the fuel cell industry for three ultrasonic coating solutions totaling approximately
$0.7 million.

The first machine is a production-level system for coating the membrane in a PEM (proton exchange membrane) electrolyzer used to produce hydrogen for a fuel cell system  The machine shipped in October to the Company’s new customer in China.  The second and third machines are also systems designed for production for coating the membranes in PEM fuel cells.  These machines are expected to ship by year end and will also be sent to two new customers in China.

“These orders demonstrate the value our technology is bringing to the fuel cell industry, both in the production of the fuel cells and the production of hydrogen to fuel them.  Our coating technology is proven to provide improved levels of efficiency in the membrane exchange process because of the quality of the surface modification in the distribution of the catalyst on the membrane.  Importantly, we have created higher value, complex solutions that have the size and speed necessary for full production level processes for the fuel cell industry,” commented Dr. Christopher L. Coccio, Chairman and CEO.   “These sales are to new customers in a market that is poised to show substantial growth as the industry continues to scale up from R&D prototype production to low rate production.  To that point, our management team will be in China meeting with these customers as we discuss follow on opportunities.”
