Changfu Chemical's Isopropanol-Based Colloidal Silica: The Ideal Choice for AR Anti-Reflective Coating

Changfu Chemical's isopropanol-based silica sol has become an ideal material in the field of AR anti-reflective coating due to its outstanding performance and broad application scope.

Reducing Reflectivity and Enhancing Light Transmission

The isopropanol-based silica sol can form a uniform nanoscale film that effectively reduces the reflectivity of glass surfaces and significantly increases the transmittance of sunlight. For example, the transmittance of ordinary ultra-white glass is about 91%, while after AR coating, it can be increased to over 95%. This significant enhancement in light transmission provides crucial support for improving the performance of optical materials such as photovoltaic glass.

Enhancing Wear Resistance and Weather Resistance

The film formed by this silica sol has high hardness and good wear resistance, significantly improving the durability of glass surfaces. Its superior weather resistance ensures that the film maintains stable performance even in harsh environments, extending the product's service life and reducing maintenance costs.

Self-Cleaning Function

The surface of the silica sol is rich in hydrophilic groups. The AR film prepared with it has excellent superhydrophilic self-cleaning properties. When it encounters water, dust can be quickly washed away by the water flow, significantly reducing the daily maintenance workload of components. This feature ensures that the glass surface remains clean at all times, further enhancing light transmission and service life, making it particularly suitable for outdoor photovoltaic components and other applications that require long-term cleanliness.

Convenient Application

The silica sol is easy to operate and does not require complex pre-treatment or stabilization procedures. Its high solid content allows for more precise control of filler dosage during addition, avoiding product performance fluctuations caused by uneven filler dispersion. This not only improves application efficiency but also ensures the stability of coating quality.

Application Fields

Photovoltaic Glass: Used for surface treatment of photovoltaic components to improve light transmission and power generation efficiency.
