Eyeglasses and sunglasses are made with plastic lenses.
The main issue is that these are very susceptible to scratches.
Hard coatings help to protect these fragile surfaces.
Hard coatings create a glass-like layer on the surface, which greatly enhances scratch resistance.
Nippon Fine Chemical has been providing hard coatings to the lens industry for over 30 years.
They are the thermal curable type coatings that provides advanced scratch resistance and weather resistance.
Our hard coatings can be cured quickly, which increases productivity.
We have several refractive index coatings to avoid fringe patterns.
Coatings provide…
