SR10 is UV-curable hard and much more scratch-resistant than most UV coatings commercially available. It can be cured under UV light in seconds. Once cured, SR10 is the only coating that adheres to all kinds of lenses including Polycarbonate, CR-39, Trivex, Mid Index, and High Index (up to index 1.74) lenses. It brings super hydrophobicity to the surface of the lens, protecting the lens from contamination. It is crystal clear and tints to a true color in about 15 minutes.

Coating quality was validated by COLTS Laboratories and is compatible not only with conventional vacuum AR (anti-reflective, anti- reflection) coatings, but also with novel sol-gel based AR coating. Due to its strong adhesion to anti-reflective coatings, the Bayer abrasion ratios after AR coatings on both SR and UT are at the top compared to other tintable hard coatings; the one on AB is close to thermally cured hard coatings. SR10 has the ingredients of stable viscosity, and is substantially solvent-free, so that its viscosity will not change much during long-term applications (six months and beyond).

SR10 is welcomed by optical labs worldwide, because it is environment- and user-friendly. It is applicable in existing lens coating machines (spin coaters), and is also miscible and co-curable with other non- volatile (NV) UV- coatings. No operational change is required for switching to SR10
