"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."

Valtech’s customer and technical services professionals resolved the issue very quickly, and in the process, made me feel like I was their most important customer.”

Our facility has been using Valtech adhesives since 2019. They worked with us until they found the adhesive that best fits our needs.
We have been able to incorporate this product in many areas, but the one that we use this for the most is for our product that goes into fighting cancer.
Recently we were on the brink of running out of the adhesive and this group of people pulled together to make sure that this did not happen. It was very important to our company and for the people that are fighting cancer.
