－Shock Resistance －UV shielding
Application
－Plastic lens coating for eyeglasses
Basic information
・n=1.60、n=1.67：Hard coating containing TiO2-based composite oxide nano colloid
・Primer：Primer containing colloidal silica and/or TiO2-based composite oxide nano colloid
Features/Characteristics
・n=1.60、n=1.67：Hrad coating that prevents interference fringe on coated substrate due to matshing of refractive index (eg. index = 1.60, 1.67) between
the substrate and the hard coating layer.
The coatings have superior abrasion-resistance and adhesion the sustrate. In addition, the coatings suppreses deterioration of plastic substrate due to
its UV shielding effect.
・Primer：The primers have high adhesion to substrate of poor adhesiveness and improve impact resistance of coated substrate.
