GENERAL INFORMATION Substance WR1 Patinal® was developed for the deposition of hydrophobic layersby vacuum evaporation. Top coatings made of Substance WR1 Patinal® on AR coated glass or plastic lenses exhibit a very low wettability by waterand therefore a lowered tendency to be contaminated by grease and finger prints. Substance WR1 Patinal® consists of carrier tablets made of an oxide mixturedoped with a perfluorinated silane. The substance is provided in three tabletsizes with different silane doping levels. No indication for a limitation of shelf life has been observed. Nevertheless, the maximum storage time should not exceed 5 years because of the organic nature ofthe hydrophobic ingredient. We recommend storing the substance in a cool anddry location at temperatures well below 30°C.
