Spraying & Chemical etching. Do you really know AG?

Someone had asked me why Touch-China' AG glass different from other suppliers, when we are supplying Chemical etching AG. Do you really know AG?

There are two production process of AG in the market: Spraying and Chemical etching.

Spraying: Spray AG is used to coat the glass surface with a coating on the surface to achieve the anti-glare effect. Spray by spray gun or disc type atomizer, by means of pressure or centrifugal force, disperse into a uniform and fine mist, applied to the glass surface.

Chemical etching: By way of HF etching, the depth of the formation of about 0.05 mm on a glass surface etching layer, the glass surface concave and convex uneven state, the original glass reflective surface into a matte surface diffusion.

Compared with Chemical etching, spraying AG has the low cost. Are they different in function? -- Absolutely Yes!

Which one is better in your opinion? I'm standing Chemical etching.
