Coating Technology in Pearl River Delta Glass Processing Industry

Coating technology is a core high-value-added process in the glass processing industry around Dongguan and the Pearl River Delta region. Its main purpose is to endow glass with special functional properties, including anti-fingerprint, water repellency, antibacterial, and heat insulation capabilities. These added functions not only meet the diverse needs of downstream applications but also significantly increase the product premium, helping manufacturers stand out in the competitive market.

In the local market, there are two mainstream types of glass coating technologies that most processing plants adopt. The first one is AF anti-fingerprint coating, which has become a standard configuration for household appliance panels, smart mirrors, and bathroom mirrors. Thanks to its ability to prevent fingerprints and oil stains from adhering to the glass surface, it greatly improves the product's appearance and usability. For manufacturers, adding AF anti-fingerprint coating can increase the processing fee by 15 to 30 yuan per square meter, bringing considerable additional profits.

The second major type is Low-E coating, which is mainly used for high-end architectural glass. It is divided into two categories: online coating and offline coating. In recent years, triple-silver and quadruple-silver high-transmittance Low-E original glass has become widely popular in the region. This kind of original glass comes with pre-applied coating, which eliminates the need for additional offline coating processes. This not only saves processing time and costs for manufacturers but also ensures the stability and quality of the coating, making it ideal for high-end building curtain walls and energy-saving doors and windows.

One of the biggest advantages of the glass processing industry in the Pearl River Delta is its complete industrial supporting system. There are dense coating processing service providers in Foshan and Dongguan, which is particularly convenient for small and medium-sized glass processing plants. Instead of investing heavily in expensive coating equipment, these small and medium-sized factories can cooperate with professional coating service providers to complete the coating process, reducing their initial investment and operational risks while still being able to provide high-value-added coated glass products to meet market demand.
