Anti-glare coating

Description

The properties of glass surface are smooth and can reflect light easily. The light reflection can be reduced by anti-glare coating on the surface.
Etching the glass with HF is the traditional way to reduce reflection effectively. But HF is highly dangerous to human and high cost for wastewater resolution. Another approach to do anti-glare is to coat a PET film and paste the PET film on glass, but the cost is fairly high. 
Giant Nano provides an anti-glare material to coat on glass directly. 8H hardness can be achieved, and smoother surface than traditional glass. 
Giant Nano also provides different water contact angles, different gloss and different charity anti-glare material depends on customer's requirements.
