Sono-Tek Creates Two Strategic Business Units, Expands Resources

Milton, NY � March 7, 2008 � Sono-Tek Corporation, the world leader in the development and application of liquid ultrasonic atomization technology into precision and liquid conserving spraying and coating application systems, announces the creation of two Strategic Business Units (SBU) reporting directly to Dr. Joseph Riemer, President, as well as the hiring of additional sales and applications development staff.

The first SBU is the Electronics and Advanced Energy unit, headed by Steve Harshbarger. Building upon expertise in the electronics industry, which has been a mainstay of Sono-Tek business for many years, the company developed unique spraying and coating applications customized for the Advanced Energy industries. In particular, Sono-Tek now offers the growing Fuel Cell and Photovoltaic Panel (Solar energy) industries, unique technical solutions and cost of goods savings which are unavailable from any traditional spraying methods, through its superior transfer efficiencies, and sophisticated controls. These systems have already been selected and purchased by leading corporations, and are being further evaluated by Advanced Energy start-up companies and R&D centers worldwide. The Sono-Tek Electronics and Advanced Energy SBU will exhibit these systems in six global trade shows in 2008.

The second SBU is the Ultrasonic Coating Solutions, headed by Luis Abarca. Performing technology transfer from its portfolio of successful industrial applications, Sono-Tek is introducing unique and superior spraying and coating solutions for a series of major global corporations in the medical industry that include stent coating, blood collection tubes coatings and ultrasonic spray drying of actives. For the textiles industry, Sono-Tek offers cost of goods savings through more efficient coating of fire retardant, anti stain and anti microbial agents onto woven and non-woven substrates. The glass and ceramics industries use Sono-Tek ultrasonic spraying of specialty coatings with proprietary functional features while saving energy and enhancing environmental friendliness. Food manufacturing and biodegradable food packaging industries recently joined the beneficiaries of Sono-Tek technology, enabling them to introduce safer food products, with longer shelf life and lower environmental impact. The Sono-Tek Ultrasonic Coating Solutions SBU will exhibit in six global trade shows in 2008.

�Sono-Tek�s business plan is to grow through investment in our capabilities to deliver unique and superior solutions for our customers. Accordingly, we have doubled the size of our marketing and sales organization, which will proactively identify, contact and introduce these capabilities to new customers. We have added application development engineers to our team, and modernized our laboratory and pilot plant so that we can readily demonstrate the value of our technology to these customers,� said Dr. Riemer.
