Serve the local shoe gum market faster with innovative speed
As the inventor of polyurethane technology, Covestro is working with industry chain partners to develop high quality, high performance and environmentally friendly polyurethane adhesive solutions with 80 years of innovation history and deep regional and global linkage of R & D and supply network , Leading the new trend of water-based adhesive technology.Recently, Covestro launched a variety of innovative research and development of innovative water-based polyurethane raw materials for shoe glue applications.Among them, Dispercoll ® U58 / 1 is a new generation for automated bonding process Water-based shoe collagen material, in line with the footwear industry automation manufacturing trends and performance in outstanding performance; Dispercoll ® U62 XP is a new one-component waterborne polyurethane shoe collagen material to meet the shoe factory to further optimize the bonding process to improve efficiency requirements .
According to Li Jinqi, vice president of technology application development of Covestro Coatings, Adhesives and Specialty Chemicals business unit, Covestro said: "Covestro has been the industry leader in waterborne shoelaces applications, especially in recent years. Demand and industry trends to bring high-performance, environmentally-friendly adhesive solutions at faster rates of innovation. Covestro is committed to promoting cross-industry collaboration including innovative collaboration with footwear brands and shoe factories , Accelerate the commercialization of new materials and achieve multi-win-win situation. '
The Shanghai-based Covestro Research and Development Center was upgraded to Covestro's Innovation Center in Asia Pacific in 2013. Today, the Center not only provides applications and developments for waterborne polyurethane adhesives to various industries, but also has product innovation capability, Better serve the local market.
Shoe glue solution for automated processes
Due to the lack of workforce and rising employment costs, the trend of production automation is rapidly developing in the footwear industry. Currently, semi-automated systems are widely used in shoe factories in China, Vietnam and Indonesia. In the coming years, with the further escalation of automation in the footwear industry Dispercoll ® U58 / 1 is Covestro's newest product for semi-automated sizing processes Dispercoll ® U58 / 1 combines excellent initial tack and post-properties such as water resistance Solubility and heat resistance, and at the same time have significant advantages in plugging resistance.It is worth mentioning that Dispercoll ® U58 / 1 has been widely used in the traditional brushing process, which effectively improves the construction efficiency due to its excellent ease of brushing. While maintaining superior performance, its extensive substrate flexibility helps designers provide greater design space and greater flexibility in material design selection.
New one-component water-based polyurethane shoe glue solution
Innovation in sports shoes industry is very active, the major brands in the appearance of style, performance and shoe-making technology continue to explore new areas of design, materials and technology to help shoe factories to streamline processes and improve bonding efficiency, Covestro launched The new one-component water-based polyurethane shoe glue solution.Compared to the traditional two-component water-based polyurethane system, the use of one-component water-based polyurethane material can save on-site mixing process, truly simple process.Other features include non-applicable period Limitations improve process ease and save equipment and labor, reduce material waste, and are suitable for automated sizing processes.
Conventional one-component aqueous polyurethane dispersions tend to perform less well at critical post-end properties such as late heat resistance and water resistance, while Dispercoll ® U62 XP has been shown to be comparable in final heat and water resistance to the commercially available For example, in the heat resistance test, Dispercoll ® U62 XP achieves results of 0.50 cm under the standard G41 test conditions, well below the normal 1.27 cm.
