Since the coating contains our weather resistance formulation technologies, the cured
film shows much better anti-yellowing property after irradiation of UV compared with
those of conventional UV curable coatings.
＊）Upper half is covered with aluminum foil to protect against UV rays.
Polarized lens needs to be cured at low temperature due to iodine series contained in the lens.
NSC-AM60 does not cause any damage to polarized lens because it can be cured at 90℃.

To avoid color-dulling of dyed lenses
In the case of hard coating of dyed Nylon lenses, conventional coatings sometimes cause color-dulling
of lenses or elution of dye to the coating liquid. NFC developed an anti-color-dulling coating by our
intensive study.
