NEI Corp.’s SR-100EC is a transparent, micron-thick coating that provides both scratch resistance and easy-to-clean properties to surfaces. It can be applied to plastics such as polycarbonate, PMMA, PET, polyurethane and epoxy, as well as metals such as stainless steel, aluminum, titanium, brass and chrome. The surface treatment is mechanically stable and highly repellent to water and oils, and enhances lubricity. By applying SR-100EC on the surface of components, soil and liquids simply slide off the surface, thereby helping prevent deposits and extending the time between cleanings, the company says.
The water-based coating is comprised of functionalized perfluoropolyethers (PFPEs), which are known for their non-stick and lubricating properties. Unlike other PFPE-based coatings that generally are less than 100-nm thick however, SR-100EC coatings have a thickness of 2-5 microns, thereby creating a more mechanically stable coating that cannot easily be removed by abrasion, harsh cleaners or chemicals, NEI says. They can be applied by dipping, spraying, roll or flow coating.
