One-component polyurethane structural adhesive is a high-strength structural bonding material based on polyurethane prepolymers that cures through reaction with moisture in the air or on substrate surfaces. It features no mixing requirement, convenient application, high bonding strength, excellent flexibility, and strong fatigue resistance. This type of structural adhesive can provide reliable structural bonding for metals, glass, plastics, composite materials, and coated surfaces, while also offering vibration damping, sealing, and weather resistance. It is widely used in automotive body assembly, new energy battery systems, rail transportation, curtain wall construction, construction machinery, and industrial equipment. Compared with traditional welding or mechanical fastening methods, one-component polyurethane structural adhesives can effectively reduce structural weight, improve NVH performance, and enhance assembly automation, and are evolving toward higher strength, lower VOC emissions, faster curing, and environmentally friendly formulations.

The upstream of the one-component polyurethane structural adhesive industry mainly includes suppliers of MDI/TDI isocyanates, polyether polyols, polyester polyols, catalysts, plasticizers, fillers, silane coupling agents, and functional additives. Representative companies include BASF, Covestro, Wanhua Chemical, Dow, Huntsman, Evonik, LANXESS, and Arkema. The midstream consists of polyurethane structural adhesive manufacturers such as Henkel, Sika, 3M, H.B. Fuller, Bostik, Mapei, Huitian New Material, which are responsible for formulation design, polymerization, automated packaging, and industrial application solution development. The downstream mainly covers automotive manufacturing, new energy batteries, rail transportation, curtain wall construction, industrial equipment, and electronics companies including Tesla, BYD, Volkswagen, Toyota, CATL, CRRC, Huawei, and Foxconn, with wide applications in body structural bonding, battery pack sealing, composite material joining, and industrial structural assembly.

The one-component polyurethane structural adhesive market continues to grow driven by demand from new energy vehicle lightweighting, power battery encapsulation, and prefabricated construction applications. Products are evolving toward higher strength, lower VOC emissions, and faster curing performance. Increasing demand for automotive body structural bonding, composite material joining, and automated dispensing is further promoting the application of high-performance polyurethane structural adhesives. Meanwhile, stricter environmental regulations, lightweight design trends, and the replacement of traditional welding processes are accelerating industry upgrades. However, the industry is still affected by fluctuations in isocyanate raw material prices, technical barriers for advanced formulations, and increasingly stringent environmental requirements. Overall, the one-component polyurethane structural adhesive market is moving toward higher performance, greener sustainability, and better compatibility with intelligent manufacturing systems.
