- “Invisible” vat lid increases dye temperature
- Yields faster tinting times
- Absorbs odor
- Saves energy
- Compatible with most lens dyes
- Odorless formula
Multi Purpose Formula (MPF) is an optical lens dye additive that increases dye temperature, speeds the dyeing process, reduces evaporation, and absorbs odor. The percentage of increase in the temperature, vapor reduction, and odor absorption depends on the quality of the lens dye and the amount of MPF added. MPF also produces better quality tint and saves energy. It works effectively with most conventional optical lens dyes.
