Surface Finishes for Capital Equipment in Industrial Cleanroom Environments

摘要

Several suitable surface finishes were evaluated and compared using different technical and economic selection criteria. It was found that technical advantages of some materials are offset by the economic advantages of others, and that the best choice is often application-dependent. The case study showed that little differentiation exists in the perceived value between stainless steel and powder coat. Stainless is a superior technical solution with respect to AMC, ESD and ESA, while powder coat has a cost advantage in high volumes. The emergence of new dissipative powder coats with low AMC and outgassing will add attractive alternatives in terms of cost and technical properties.
