FINESET Fineset brand OCA optical glue has been fully imported into major international and domestic customers

With the rapid development of smart phones, the touch display industry is showing a trend of explosive growth. As one of the important materials of touch screen, OCA optical glue has many advantages, such as excellent optical performance, filling, ITO compatibility and reliability. Gradually penetrate into the fields of vehicle display and smart wearables. The global market size of OCA optical glue will also grow rapidly from US$900 million in 2017 to US$1.05 billion in 2020.

For a long time, the high-end OCA optical glue used for the full bonding of touch screens has been basically monopolized by international material giants. Companies such as Mitsubishi Chemical in Japan and 3M in the United States have a high market share. The performance is not up to standard, and only occupies part of the low-end rework market and the general lamination market with lower requirements.

At present, this situation has been broken by Suzhou FINESET Material Technology Co., Ltd. Since the acquisition of the OCA Optical Adhesive Division of Japan's Hitachi Chemical Co., Ltd. in 2016, Suzhou FINESET Material Technology Co., Ltd. has launched a comprehensive introduction of well-known domestic and foreign adhesives with product innovation as the core, intelligent demonstration workshop as the platform, and customer demand as the guide. It fits the journey of the supply chain of module manufacturers and consumer electronics terminal brand customers, and has made significant progress after one year of production.

Independent research and development, building a product innovation platform

Hitachi Chemical Co., Ltd. is one of the originators of the world's optical adhesive industry with a long history. The technical level and product performance of its OCA products are at the same international advanced level as 3M and Mitsubishi. By purchasing Hitachi Chemical's technology platform, patents and equipment, FINESET established the first and currently only factory in China capable of producing high-end full-fit OCA optical adhesives in Zhangjiagang Free Trade Zone. In March 2017, it had initial mass production capacity and started The certification imports well-known international and domestic customers.

At the beginning of its establishment, FINESET established a business philosophy centered on research and development and oriented to product performance. Establish a cutting-edge technology research and development center in Japan, and establish an independent research and development innovation platform in Zhangjiagang. By digesting and absorbing Hitachi's existing technologies, combining the technological advantages of the Japanese R&D center with the advantages of the Chinese R&D team being close to the market, and continuously developing and innovating. So far we have 19 patents have been authorized, and more than ten new patents have been applied for. Since 2016, it has won honors such as Jiangsu High-tech Cultivation and Storage Enterprise, Suzhou Demonstration Smart Workshop, etc.

With the upgrading of touch display products such as ultra-thin, ultra-narrow bezel, full screen, flexible screen, and vehicle, the conventional full-fit OCA can no longer meet customer needs. The R&D center teams in Japan and China have focused on the continuous improvement of R&D technology and production technology, realized product upgrading and innovation, and developed a series of new OCA optical glue products. The new product itself not only has excellent optical performance and adhesion, but also has excellent performance in step filling and environmental reliability. Especially in terms of reliability, there is no bubble rebound phenomenon under 85°C, 85%RH, 1000H, xenon lamp aging test, and QUV aging test conditions, which can adapt to complex sea, land and air transportation conditions and extreme cold and extreme heat. conditions, which can meet the demanding requirements of vehicle users. At present, the FINESET product group covers the whole application field of touch function chip lamination, hard-to-hard full lamination, and bendable flexible display lamination, providing excellent material support for customers to develop high-performance display products.

In terms of production capacity layout, the four intelligent precision coating production lines imported from Japan have all been installed and debugged. After successfully digesting and absorbing Hitachi's technological advantages and OCA mass production experience, the production capacity has been continuously released, which can provide the market with an annual output of 360 Ten thousand square meters of OCA optical glue production capacity supply, the second phase of the plant with an annual output of 4 million square meters of optical glue is already under construction. In an environment full of uncertainties in the international trade environment, FINESET helps domestic and foreign customers stabilize the supply chain by expanding production capacity in China and improving the localization level of OCA.

Hand in hand with customers to grasp the new era of touch screen industry

After more than a year of hard work, with the strong cooperation and integration of customers, FINESET's products have been gradually promoted in the Chinese market, and have gradually entered the supply system of well-known international and domestic customers.

In the field of smart phones, FINESET's OCA products have passed the strict test of Tianma Microelectronics Co., Ltd., a well-known domestic display manufacturer. The gap filling model has been confirmed to be used in the latest models of domestic first-line brands; at the same time, through the cooperation with the well-known domestic module manufacturer OFILM, FINESET's OCA products have also been recognized by customers in some projects of Huawei mobile phones.

FINESETOCA products also performed brilliantly in tablet PCs, notebooks, e-books and other consumer electronics fields. In the GIS Industry Group under Foxconn, FINESET's OCA products have been applied in notebook computers of many first-line brands such as Microsoft, Lenovo, and HP; In order to support mass production; especially through the cooperation with TPK Chenhong, FINESET's high-reliability OCA products have won the performance in the PK competition with major international brands. In June, they won a large order for Amazon e-book products, and customer technical experts praised FINESET "You are our hero".

2018 is the first year of in-vehicle intelligent display. Driven by Tesla, BMW, Mercedes-Benz and other internationally renowned automakers, Smart car has been regarded as another market focus after Smart phone. The human-vehicle interaction interface is naturally separated. Do not develop large-size, high-performance display and touch products. On the basis of the original Hitachi vehicle-mounted products, FINESET has developed a new generation of acrylic system vehicle-mounted OCA products by optimizing the formula and improving the production process. It is the only OCA product in the market that can compete with expensive liquid silicone hydrogel products in the vehicle-mounted market . At present, through the cooperation with Sharp, it has achieved mass supply in high-end models of BMW and Ford.

epilogue

FINESET has always maintained the rhythm of common growth and common development with customers, and is constantly making the road of advanced OCA optical adhesive materials wider and farther. Through the support of upstream and downstream, joint development and establishment of strategic partnership with customers, Suzhou FINESET will surely become a Chinese OCA optical adhesive production base with international competitiveness.
