Optisolv® OP7171 is an aqueous blend created to be effective for cleaning optical lenses prior to coating. Optisolv OP7171 is also effective in cleaning medical and bio-medical optics, and semiconductor wafer boats. OP7171 is diluted further with water as required depending on the intensity and amount of soil to be removed. A rinse is recommended to remove all residual soils and cleaner solids from the part surfaces. A vacuum or filtered hot circulating air drying stage completes the process. OP7171 is designed for use in spray-in-air and may also be used for brush or hand cleaning applications.
