At present, LED glue shipments in the largest application in the field of lighting, and small and medium power products (≤ 1W) is the mainstream lighting market, technical development cannot be separated from market demand. At present, in the lighting market, the most failure problem encountered by the terminal is still curing black, lighting black and lighting dead lamp, which is closely related to the characteristics of packaging glue is curing resistance, high temperature blackening and cold and thermal impact resistance. As a result, these three requirements have dominated the technology development of the mainstream LED packaging glue. As the quality of the matching material of the sealing factory decreases, the requirements of these three aspects of LED glue are becoming higher and higher.


Solely from the characteristics, the current market mainstream in the sale of domestic LED glue has been in the industry leading level, continue to improve the challenge is very big, from the dimension of formula design has almost reached the limit of performance balance. To breakthrough, the characteristic of the above three key must start to consider to design of LED encapsulation adhesive key raw materials, formula from raw material of organic silicon polymer groups in quantity, structure and molecular weight of polymer design, from the source to solve formula curing the microscopic material performance, can be a breakthrough in performance further, break the limit of the formula design. LED silicone commonly used silicone polymer, because the application field is too segmented, the market has not seen the sale of high-performance products. Therefore, for the niche application field of organic silicon -- LED packaging silica gel market, only r&d enterprises with independent development and production of organic silicon intermediates and active investment in RESEARCH and development layout can survive. This is also the reason why in recent years, domestic suppliers of high-end LED packaging adhesive that can meet the needs of major customers are gradually concentrated, and whether the main sealing factories have the organic silicon synthesis technology is also one of the important indicators to consider when choosing the packaging adhesive supplier in recent years.
