Amino fluorosilicone oil has recently achieved a major technological breakthrough in the fields of specialty adhesives and interface treatment for high-performance composite materials. Through the synergistic design of amino functional groups and fluorosilicon segments within its molecules, this material has successfully addressed the industry challenge of balancing high bonding strength with environmental aging resistance between advanced materials, providing a new generation of interface treatment solutions for aerospace, new energy, and precision electronics manufacturing.

Research indicates that the unique molecular structure of amino fluorosilicone oil allows its surface energy to be regulated to 20-25 mN/m, demonstrating excellent initial wettability and reactivity towards various difficult-to-bond substrates including metals, ceramics, engineering plastics, and specialty rubbers. Bonding interfaces treated with it achieve peel strength of 8-15 kN/m, representing an improvement of over 300% compared to traditional silane coupling agents. Long-term aging tests show that bonded components retain more than 90% of their strength after 1,000 hours in a high-temperature and high-humidity (85% RH) environment at 150°C, with stable performance during thermal cycling from -55°C to 200°C.

In the structural bonding of new energy vehicle battery packs, bonding solutions using amino fluorosilicone oil as a primer not only meet high-strength requirements between aluminum alloy housings and composite fire shields but also provide excellent resistance to coolant corrosion and electrochemical migration, offering critical assurance for the overall safety and lifespan of battery systems. In the aerospace sector, the material has been successfully applied in the co-curing bonding process of carbon fiber composite components and titanium alloy frameworks, significantly enhancing the integrity and reliability of lightweight structures.

With the increasing demands for lightweight and integrated design in high-end equipment, a series of advancements have also been made in the modified applications of amino fluorosilicone oil in structural adhesives, thermal interface materials, and conductive adhesives. Its derivative products can integrate functions such as thermal conductivity, electrical conductivity, or electromagnetic shielding while providing composite material interfaces with excellent bonding performance. Market analysis suggests that this breakthrough material will significantly drive the iteration of high-end bonding technologies and is expected to see widespread application in electric vehicles, semiconductor packaging, and advanced aircraft manufacturing in the coming years, fostering an emerging market worth tens of billions of RMB.
