Liquid optical adhesive (LOCA) is in strong demand in the field of electronic products, and the high-end competitiveness of local companies needs to be improved.

Liquid optical adhesive (LOCA) is a special adhesive that appears as a colorless and transparent liquid. Liquid optical adhesive has the advantages of high bonding strength, high light transmittance, resistance to yellowing, and low curing shrinkage. It has broad application prospects in many fields such as electronic products, aerospace, national defense and military, and automobile manufacturing. According to different processes, liquid optical adhesives can be subdivided into two categories: ordinary liquid optical adhesives and scraper-coated liquid optical adhesives (SLOCA).

Optical glue is an important material for bonding optical components and was first used in the aerospace field. Due to factors such as high technical barriers, my country’s optical adhesives are highly dependent on imports. The 3M Group of the United States, LG Chemical of South Korea, and Mitsubishi Chemical of Japan are my country’s main suppliers. In recent years, driven by national policy support and market prospects, the number of companies in my country’s optical adhesive industry has continued to grow. Liquid optical glue is a segmented product of optical glue. As the development of the optical glue industry accelerates, the market space of liquid optical glue will expand accordingly.

Blade-coated liquid optical adhesive (SLOCA) refers to an optical adhesive made from ordinary liquid optical adhesive as a base material using a blade-coating process and a UV pre-curing process. The scraper-type liquid optical glue combines the advantages of liquid optical glue and OCA optical glue, and will not cause glue overflow during the bonding process. As the demand for blade-coated liquid optical adhesives increases, the prosperity of my country’s liquid optical adhesive industry will increase.

According to the “2023-2028 China Liquid Optical Adhesive (LOCA) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center 》 shows that compared with traditional optics, liquid optical adhesive has the advantages of high cost performance, high reliability, and seamless bonding, and is widely used in many fields. Currently, the field of electronic products is the largest demand end for liquid optical adhesives, which can be used to bond mobile phone touch screens, computer displays, TV displays, etc. As electronic product updates and iterations accelerate, my country’s demand for liquid optical adhesive applications will further grow.

The main players in my country’s liquid optical adhesive market include Jinfu Technology, Xinya Processing, Youtemei Adhesive Industry, etc. At present, my country’s liquid optical adhesive market has a small number of participants, and high-end demand is highly dependent on imports. Xinya Processing is a representative company of liquid optical adhesives in my country. Its subsidiaries, Kutech Electronics and Xinya New Materials, focus on the research and development, production and sales of new chemical materials. They have liquid optical adhesives, RTV silicone rubber, underfill glue and other product batches. Supply capacity. According to the financial report of Xinya Processing Company, in the first quarter of 2023, the company achieved revenue of 470 million yuan, a year-on-year increase of 16.3%.

Industry analysts said that liquid optical adhesives are fully laminated optical adhesives, with strong demand in the field of electronic products, and the development prospects of the industry continue to be positive. good. In recent years, Chinese companies have continued to increase their investment in research and development of liquid optical adhesives, which has accelerated the localization process of its market. Overall, my country’s liquid optical adhesive industry still has huge room for development.
