The optical protection lacquer M-9 SO2-ST is a further development of our synthetic artificial resin protective lacquer M9-SO2. By adding new specialty resins, we were able to improve drying time, bond strength and significantly increase surface stability.


The M 9 SO2-ST is used as a protective or adhesive lacquer in the optical production. Due to the improved adhesive properties, this lacquer can be used to protect matt or polished surfaces against water, certain cutting oils or other mechanical affects for a much longer time. A detachment or contaminating of the surfaces is thereby prevented at the same time. The application can be done by brushing, spraying or dipping. Dilution of the lacquer may only be carried out with butyl acetate.
