Difference between AR/AF/AG Coating

AF, AR, AG, as the three mainly used surface treatment methods in glass processing, there are obvious difference between them.

1.AF —- Anti-fingerprint: Principle: The AF anti-fouling and anti-fingerprint glass is based on the lotus leaf principle. A layer of nano-chemical material is coated on the outer surface of the glass to minimize its surface tension, reducing the contact area between dust and the glass surface by 90%. This results in enhanced water-repellent, anti-oil stain, and anti-fingerprint abilities, allowing the screen glass panel to maintain a bright and clean effect for an extended period.

2. AR —- Anti-reflection: Principle: When light passes from a light-thin material to a light-dense material, reflected light experiences a half-wave loss. By coating the glass with AR film, the optical path difference of reflected light on the surface becomes exactly half a wavelength. This causes cancellation of reflected light on both front and back surfaces of the film, effectively increasing transmitted light energy. Coating both sides of the glass simultaneously reduces reflection effects.

3. AG —Anti-glare:

Principle: Through scattering and diffuse reflection of light, AG aims to reduce glare and vertigo while enhancing clarity.

Features 

1. Features of AF coating products: 

- Anti-fouling: Prevents fingerprints and oil stains from sticking. 

- Anti-scratch: Smooth surface that is resistant to scratching. 

- Thin-film: Excellent optical performance without altering original texture.

2. Features of AR coating products: 

- High light transmittance: Utilizing nano-level optical coating technology, the light transmittance of ultra-white glass can be increased by 2-3%. 

- Long-lasting durability: Capable of maintaining effectiveness for 25 years even in harsh environmental conditions. 

- Condensation prevention: Significantly suppresses condensation on photovoltaic glass surfaces.  - Water repellent: Water droplets form an angle >110° on the surface, allowing them to slide off when tilted without obstructing visibility. 

- Easy maintenance: Reduces dirt accumulation by 80%, making cleaning extremely effortless. 

3. Features of AG coating products:

 - Infrared reflection reduction: Decreases the transmission of infrared light through the glass surface to minimize infrared exposure indoors.

 - Enhanced light transmission: While reflecting infrared light, it improves the transmission of other light sources without compromising indoor lighting effects. 

- Anti-glare properties: Emits diffuse reflection similar to that produced by the original light source, altering visual perception and reducing glare for observers.
