À quels matériaux de chaussures est-il adhésif PU à base d'eau principalement adapté? (1) Avec des agents de traitement de surface appropriés, l'adhésif PU à base d'eau peut essentiellement être appliqué à la plupart des matériaux de chaussures. (2) Pour les tissus poreux ou les matériaux facilement érodés par les solvants, les produits à base d'eau ont un avantage très évident. (3) Les matériaux avec une teneur en huile relativement élevée et en particulier la tension ne sont...
As one of the earliest latent curing agents, dicyandiamide endows the cured epoxy resin with excellent mechanical properties. However, it still has drawbacks such as a relatively high curing temperature. In view of this defect, this paper summarizes the domestic and foreign literature from two aspects: reducing the electron-withdrawing ability of the cyano group on dicyandiamide to enhance the curing activity and introducing similar groups to improve the compatibility between dicyandiamide and...
Recently, the China Academic Journals (CD-ROM Edition) Electronic Publishing House Co., Ltd. and the Chinese Science Literature Quantitative Evaluation Research Center jointly released the "Annual Report on Impact Factors of Chinese Academic Journals (Natural Sciences and Engineering Technologies・2024 Edition)" (hereinafter referred to as the 2024 Edition of the "Annual Report"). Both the compound impact factor and the comprehensive impact factor of "China Adhesives" have increased...
lingwogroup UV glue mainly designed to achieve better thermal shock resistance performance at greater thicknesses, especially in the higher meniscus areas between adjacent SMT components where the coating thickness exceeds 125um. UV500-2 retains all the characteristics of the UV gluematerial, including: excellent thermal stability; long-term stable electrical characteristics; low modulus and low Tg, a softer and more flexible material; excellent performance in thermal shock tests. In key...
Nowadays, the significance of an innovative product has transcended the use of the latest cutting-edge technologies such as artificial intelligence. Enterprises need to be driven by sustainable development goals to promote product innovation. For manufacturers, there are many opportunities to adopt innovative solutions that can save energy, conserve water, and extend product lifespan, thereby helping them fulfill their sustainable development commitments. However, changing a long-established...
The development history of epoxy resin AB glue for LED packaging ranges from the application of the initial liquid bisphenol A epoxy resin to the application of alicyclic epoxy resin and, most recently, silicone - hybrid alicyclic epoxy resin. It focuses on sharing the formulations, properties, and domestic and international research progress of epoxy resin glue for through - hole LED and Nixie tube packaging, epoxy resin AB glue for SMD RGB packaging, and epoxy resin AB glue for Mini LED...
Due to its excellent properties, epoxy resin has been widely used in fields such as adhesives, coatings, and composite materials. In order to increase the curing rate, and for some heat - sensitive components, temperature is an important factor and it is necessary to lower the curing temperature. Therefore, adding curing accelerators is essential. This paper mainly reviews the research progress and application status of epoxy resin curing accelerators, including tertiary amine and its salt -...
LINKWORLD NEW MATERIAL CO., LIMITED 【Abstract】Theresearch progress of SIS-based hot melt pressure sensitive adhesive and polyurethane hot melt pressure sensitive adhesive at home and abroad was reviewed in this study. The advantages and disadvantages, modification methods (such as polymerization modification, physical blending modification, chemical modification), and research and application fields (such as metal bonding, logistics labels, building waterproofing materials, and medical...
I. Technical Background In recent years, the global electronics industry has been developing rapidly, and the industry scale has expanded significantly, which has greatly driven the development of the electronic adhesive materials industry. Although electronic adhesive materials account for a relatively small proportion in the entire adhesive materials family, they are highly concerned in the industry due to their high value-added characteristics. This kind of adhesive needs to have key...
