Our nano silica dispersion works as a filler of hard coating and improves hardness, anti-scratch property, anti-blocking property of optical films (e.g. PET, TAC, PC, PI etc.) which is used for displays of smartphone and laptop.
Substrate:PET(125μm)
Thickness:5μm
SiO2:30phr
Resin:Urethane acrylate
Abrasion:Φ27mm, 500g load×100 times; number of scratch
Nano silica improves pencil hardness and scratch resistance of films without deteriorating haze.
