In recent years, China’s adhesive industry has made considerable progress, as evidenced by the following aspects.
(1) With the continuous emergence of new products, a series of modified, resource-saving, copolymer-blended, and specialty adhesives have been successively developed and have now achieved industrialization. Examples include polyurethane-modified polyvinyl acetate emulsions, freeze-resistant white latex adhesives, bismaleimide-modified epoxy resin conductive adhesives, and organosilicone-modified epoxy resin structural adhesives. These products boast numerous outstanding properties; not only do they meet diverse application requirements, but they have also elevated the quality level of China’s adhesive products and partially replaced imported alternatives.
(2) With the accelerated advancement of production technologies, China’s adhesive manufacturing processes have made significant progress. New production technologies—such as radiation curing, ultraviolet curing, and interpenetrating network methods—have played a crucial role in enhancing product performance and improving the quality of manufactured adhesives.
(3) The application fields are continually expanding. Currently, adhesives have permeated into every sector of the national economy, including apparel, light industry, mechanical manufacturing, aerospace, electronics and electrical appliances, transportation, healthcare, postal services, warehousing, and many other areas, becoming an indispensable technology in industrial production.
In the automotive industry, adhesives are used for their simplicity of processing, reliable performance, and cost-effectiveness. They are employed for structural bonding, fastening, and sealing—whether between metals, plastics, fabrics, glass, rubber themselves or among these materials as well as with painted surfaces.
Epoxy structural adhesive:
In the aerospace industry, it is extensively used to manufacture composite structures such as honeycomb sandwich structures, composite metal structures, and metal-polymer composites, serving as applications like wing skins, fuselage panels, satellite structures, and rocket engine casings.
In the shipbuilding industry, it is used for bonding propellers to tail shafts and for bonding crankshafts.
In the mechanical manufacturing industry, sleeve-inlaid bonding is used for lead screws in heavy-duty machine tools; this method offers higher precision and strength than solid lead screws.
