Anti-reflection for glass substrate

Description

Traditional anti-reflective coatings are applied to glass substrates using vacuum processes, but this method significantly increases the cost of glass and has limited applications in the market. Using a wet coating method can effectively reduce costs. This application can be extended to the fields of monitors, the photovoltaic industry, and construction. Our company's product can be processed at room temperature without any special treatment, such as heating or cooling. Another advantage of this product is that it does not contain hexavalent chromium and RoHS hazardous substances. Wastewater does not require special treatment, ensuring environmental friendliness and saving users' wastewater treatment budgets.

  2. Excellent stability / Safety
  3. Easy to use, no need to add other chemicals
  4. Inorganic materials
  5. Porous material
  6. Low refractive index
  7. High transparency
