Visit Sono-Tek at Hannover Messe 2012

Sono-Tek will be exhibiting at Hannover Messe 2012 H2 & FC Fair April 23-27 at the Hannover Exhibition Grounds in Hanover, Germany, booth C76/1 with Rubroder GmbH Factory Automation.

Ultrasonic nozzles produce highly durable, uniform, pinhole free coatings of carbon based catalyst inks onto fuel cell proton exchange membranes such as Nafion, without deformation of the membrane. Sono-Tek has become the industry’s leader in applying uniform homogeneous dispersion of carbon catalyst ink suspensions. Our unique technology allows greater control of layer thickness, dryness of the spray and uniformity across the surface area and depth of the coating. Ultrasonic vibrations continuously deagglomerate particles and keep them evenly dispersed, resulting in uniform dispersion of precious metal particles throughout the entire coating. This translates to the highest possible functional characteristics of the coating. Ultrasonic coatings are durable and highly repeatable.
