"Disk drives are unique within the electronics industry in that they must maintain and extremely clean internal environment throughout their operational life. Valtech was successful in delivering uniquely qualified surfactant systems for both metal and polymer-based drive components. The qualification phase was aided by a top tier R&D center, and the switch to full production was backed up by great customer support as well as trouble-free worldwide distribution."
