Glass protection ink

The bottleneck problem of touch glass mentioned by manufacturers is, first of all, environmental protection safety regulations. In recent years, local governments in mainland China have attached great importance to industrial environmental protection issues. Process emissions with serious emissions and heavy pollution are subject to strict supervision, and penalties can be severe enough to order the shutdown of factories. In the past, manufacturers used UV-hardened peelable glue to protect the surface integrity of the glass during the cutting process, but they needed to be soaked and stripped with NaOH strong alkali solution afterwards. Now there is no factory for sewage treatment and discharge. Therefore, Crown Chemical provides manufacturers with a new U2 UV curable surface protection ink, which has good water resistance and scratch resistance. It can be coated with screen printing and then cured with UV light to form a good protective film, which can avoid damaging the precise glass surface during cutting. After the cutting process is completed, soak and strip with Na2CO3 sodium carbonate weak alkali solution. This UV-curable glass cutting protection ink has attracted much attention. In addition to solving the problem of environmental protection in the process, it is also very suitable for stacked glass cutting developed by mainland manufacturers in large-scale production.

Solve the cleaning problem of ITO touch glass

In addition, manufacturers are faced with the cutting of ITO touch glass. The cutting protection ink used at this stage is too sticky. When cleaning afterwards, the sputtering line will be damaged if the solvent concentration is too high. The solvent concentration is low and cannot be washed cleanly, and residual ink remains, which will affect the output quality and efficiency. Therefore, there is an urgent need for a protective ink that can completely protect ITO touch glass and clean quickly and easily. Crown D4 glass cutting protection ink, completely environmentally friendly, tasteless and non-toxic, after coating 120 degrees Celsius baking 1~3 minutes to dry can be cut. After the construction is completed, it can be washed with water. The material cost is low, the construction is simple, the equipment is cheap, and the cleaning is easy. It can be said to be the most suitable protective ink for touch glass cutting. Crown products have been mass produced and shipped. According to the evaluation of the use experience of crown D4 glass cutting protection ink by the users, they generally believe that the quality is no less than that of Japanese products of the same level, cheaper than Japanese products, and the working hours and equipment are much simpler.

According to a research report by Bai Dewei, a researcher at the Optoelectronic Research Center of Tuo Yun Industry Research Institute, the focus of touch panel technology shifted from Japan to Taiwan and South Korea in the early days, and is now gradually moving westward to the mainland. Although some of the key chemical materials of touch panels, including ITO film and silver glue, are still in the hands of Japanese and American manufacturers, Taiwan and mainland manufacturers have mass production capacity in ITO glass and touch IC. At present, the global touch panel shipments rank among the top 10 manufacturers. Cross-strait touch panel manufacturers include Yanghua, Interface, Shiwei, Chen Hong, Huayi Circuit, Xinli Truly, Nanjing Huaruichuan, Shenzhen Shenyue Optoelectronics, etc. have all entered the list and continue to actively expand production this year. Chen Feng, general manager of Shenzhen material agent Jin Honghua Ye, said that the huge market potential of fake machines is not easy for ordinary industry analysts to see. However, suppliers who have gone deep into this market have found that the yield of glass cutting is related to the cost. As long as new material development can reduce the cost and simplify the manufacturing process, the acceptance of mainland manufacturers is faster than that of any other country. Therefore, he has a high willingness to promote the glass cutting protection ink and UV-curable peelable adhesive newly developed by Taiwan Guanpin Chemical and immediately send samples to major manufacturers.

Liu Bangqing, associate manager of Guanpin Chemical Business Department, said that Guanpin's introduction of special cutting protection ink and UV-type peelable glue for touch glass is an extension of the application of special glue technology. With Taiwan manufacturers ranking the most important supply position of smart phones and touch screens in the world, the attention to the development of the latest applications of special materials should be the most sensitive intuitive instinct of Taiwan manufacturers. The change of materials is often an important factor in triggering the industrial revolution. Taiwan may not be able to become a leader in the research and development of new materials, but it definitely has the strength to run first in application. Guanpin hopes that various high-performance glues and lacquers made with unique technologies will be widely used in various industries, resulting in a close relationship like glue and lacquer.
