AR942 Anti-reflection Coating for Solar Glass

Product Details

1. Main Properties

Pencil Hardness level up to 4H.

Performs better than waterborne AR coating in terms of transmittance boost.

Stable for over 3 months from date of manufacture.

2. Highlights

Operative under 40%-60% RH condition, such as raining season or humid climate at the sea side.

Up to 93.9% or higher light transmittance.

3. Main Ingredients and Field of Use

Porous silica resin, water, a small sum of organic solvent.

Intended to be used on photovoltaic glass to increase the transmission of light.

4. Coating Process Instruction

Application Method: roller coating

Working condition: RH40-60; temperature @ 20±2℃ and cleanliness @ class 100000.

Desired thickness of dried coating layer: 110nm.

Thinner: IPA recommended.

Baking: 200℃ for 1-2 minutes.

Tempering: 720℃ for 2 minutes.

5. Storage and Shelf Life

The coating sol will be stable even at ambient temperature (below 25°C) for 6 months from date of manufacture. The coating liquid should be stored in a dry place. Keep the containers tightly closed and protected from sources of UV light. The coating liquid may spoil if stored with ambient temperature below 0°C.
