PS Light Guide Panel can significantly improve its durability and anti-aging performance through surface treatment process, ensuring that its optical performance and appearance are not affected during long-term use. The following are several common surface treatment processes and their effects on improving durability and anti-aging performance:

1. UV coating (ultraviolet curing coating)
Function: By applying a layer of UV coating on the surface of PS light guide plate, the light guide plate's resistance to ultraviolet (UV) radiation can be effectively improved. This coating can prevent the material from yellowing or aging when the light guide plate is exposed to sunlight or other UV sources for a long time, and maintain optical performance and appearance.
Advantage: UV coating can not only prevent yellowing, but also improve scratch resistance and pollution resistance, making the surface of the light guide plate more durable. Especially in outdoor or high UV environment, UV coating can effectively extend the service life of the light guide plate.
2. Anti-scratch coating
Function: Applying anti-scratch coating on the surface of light guide plate can improve the hardness and wear resistance of the surface, and reduce surface scratches caused by friction or collision during daily use. This can prevent scratches from affecting the introduction and distribution of light and maintain uniform light effect.
Advantages: Enhanced scratch resistance makes the light guide plate more durable and suitable for high-frequency use environments such as public places, commercial billboards, etc. In addition, this coating can also increase the light guide plate's anti-pollution ability, avoid the accumulation of dust or oil, and facilitate cleaning.
3. Anti-oxidation coating
Function: Anti-oxidation coating can prevent the light guide plate material from oxidizing due to long-term exposure to oxygen, moisture or pollutants in the air. Although the PS material itself is relatively stable, in a humid or high-temperature environment, the surface of the light guide plate may be slightly oxidized, affecting the light-guiding performance.
Advantages: The anti-oxidation coating can enhance the stability of the PS light guide plate in a humid or high-temperature environment, avoiding fading, aging or brittleness of the surface. It is particularly suitable for light guide plates that need to be used in a variety of environments.
4. Anti-ultraviolet (UV) light stabilizer addition
Function: In the manufacturing process of the PS light guide plate, adding anti-ultraviolet stabilizers or light stabilizers can improve its resistance to ultraviolet rays. These additives can react with UV light inside the material, absorb or convert UV light, thereby reducing the damage caused by UV light to the surface of the light guide plate.

Advantages: This process improves the durability of the light guide plate under sunlight exposure, avoiding yellow aging and surface roughness of the light guide plate after long-term use. It is particularly suitable for applications exposed to ultraviolet rays for a long time, such as outdoor advertising, car dashboards, etc.
5. Coating process (such as fluoride coating)
Function: Through coating processes such as fluoride coating, silane coating, etc., a transparent protective film can be formed on the surface of the PS light guide plate. This film can improve the water resistance, stain resistance, oil resistance and chemical resistance of the light guide plate, and reduce the impact of the external environment.
Advantages: The coating can prevent water droplets, oil stains or other chemicals from penetrating into the surface of the light guide plate, maintaining its surface cleanliness and light guiding effect. In addition, the coating layer can also increase the hardness of the surface and enhance the scratch resistance.
6. Heat treatment or surface hardening
Function: The heat resistance and anti-aging performance of the PS light guide plate can be enhanced through heat treatment or surface hardening process. The heat treatment process can improve the molecular structure of the material and increase its resistance to temperature difference changes and fatigue.
Advantages: This process is particularly suitable for light guide plates used in high temperature environments. It can improve their stability at high temperatures and reduce performance degradation caused by thermal expansion or temperature fluctuations.
7. Antistatic treatment
Function: Antistatic treatment can reduce dust accumulation on the surface of the light guide plate and avoid static adsorption of dust or particles. The accumulation of dust and pollutants not only affects the optical performance, but may also cause surface wear and aging.
Advantages: Antistatic coating can ensure that the light guide plate remains clean for a long time, reduce the frequency of frequent cleaning, and thus extend its service life. At the same time, it reduces surface damage and reduced light guide efficiency caused by dust accumulation.
8. Nano coating technology
Function: Nano coating technology can form a nano-level protective film on the surface of the PS light guide plate. This film has excellent water resistance, anti-fouling, anti-ultraviolet and anti-corrosion properties. Nano coating can not only improve the anti-aging property of the light guide plate, but also improve its optical properties and improve the efficiency of light introduction.
Advantages: Nano coating can significantly improve the durability of the light guide plate, so that it can maintain stable performance for a long time in harsh environments. It is particularly suitable for products that need to maintain light effects for a long time, such as high-end display screens, billboards, etc.

By reasonably selecting and applying these surface treatment processes, it can ensure that the PS light guide plate maintains the best performance in different usage environments, prolong its service life, and ensure long-term stable light guide effect.
