Photocatalyst coating glass

Description

Photocatalyst  depends on light energy to achieve disinfection, sterilization, and self-cleaning effect. Current photocatalysts made ​​of sintered powders are mostly dissolved in a solution of the appropriate dispersing solvent. However, the adhesion on glass and transmittance are usually poor. Giant Nano develops the photocatalyst which has overcome disadvantages of adhesion and penetration degree. Light can effectively filter out and reflect through the product even for short wavelenght light source.
The application of photocatalyst is mainly on glass, but it can also apply to other substrates. Scope can be exteneded to different industries needed to deploy and process.
