Differences Among Etched AG | Sprayed AG | Coated AG
We believe everyone has heard of many types of glass, such as bulletproof glass, tempered glass, anti-slip glass, etc. Today we are going to introduce you to a type of glass that you may have never heard of - AG glass.
AG Glass , means Anti-glare Glass.
What is AG glass?
The so-called AG glass: also known as non-reflective glass or low-reflective glass , is a kind of glass with special treatment on the surface. Anti-glare glass is a high-quality glass sheet with a single or double-sided special process, which makes it have a lower reflectivity than ordinary glass, and the light reflectivity is reduced from 8% to less than 2%, creating a clear and transparent visual space, allowing viewers to experience better visual enjoyment.
Conventional glass parameters include: transmittance, glossiness, roughness, haze. Some also need to test parameters such as particle span and flash points.
Classification of AG glass:
AG glass can be divided into three categories: etched AG , sprayed AG, and coated AG. Which AG glass has a better anti-glare
Effect among etched AG, sprayed AG, and coated AG
Let's first distinguish them:
1. Spray AG:
A layer of micro-particle "attachment" is solidified on the glass surface by spraying, and it only relies on intermolecular force to combine with the glass surface to achieve the anti-glare effect. This processing technology is relatively convenient and fast, has high production efficiency and low cost, and is convenient for processing glass products with different gloss and haze.
The disadvantage of spraying is that the coating material may fall off and become partially blurred due to writing friction, ink dissolution, sweat corrosion, temperature and humidity changes, etc., which directly leads to blurred images, inaccurate positioning, misoperation, etc., seriously affecting the experience. , short service life, frequent replacement, and its parameters are difficult to make major and obvious adjustments.
2. Coated AG:
AG coating (anti-glare coating) is a kind of atomized coating technology. The industry term for AG anti-glare film is called polarizer surface treatment, which is a type of polarizer surface treatment. By applying fine uneven processing to the surface of the polarizer, light is prevented from entering the eyes directly, thereby effectively reducing glare and reflection. Originally applied to car rearview mirrors, let’s take a look at the renderings:
The processing technology of coated AG determines that its hardness value is difficult to change. Coated AG will become scratched after being used for a period of time, and the handwriting feel is not far from the general handwriting on paper. Therefore, its scope of application is limited. It is basically only used on rearview mirrors, and a small amount is used on TV screen glass and navigation instrument glass. Since the requirements for AG glass have become higher and higher, coated AG has gradually come out of the market.
3. Etched AG:
Produced by chemical etching process, its characteristic is that the original glass reflective surface becomes a matte diffuse reflective surface. It can blur the reflection effect, prevent glare, and also reduce the reflectivity and reduce light and shadow. Anti-glare products have strong surface anti-corrosion and anti-scratch properties. Solve the problem of reflection and glare caused by electronic video screens and image screens under ambient light sources.
AG etching is chemical etching. After AG treatment, the surface is still glass. Since the surface is still glass in nature, the product life is equivalent to that of general tempered glass. The etching surface has uniform particles, which cannot be achieved by the first two processes. So what are the advantages of etching AG? First, let’s take a look at the roughness range that Henghao can achieve by etching AG between 0.06-2.8, and the glossiness The highest it can be is 10-130, the transmittance is 82%-93%, and the haze is 1%-70%.
AG glass is mostly used in the fields of automotive AG, mobile phone AG, educational AG, industrial control AG, etc. Such as: car display, TV screen, electronic whiteboard blackboard, computer display, medical display, mobile phone cover, mouse board, advertising machine screen, all-in-one screen, etc.
