Latest Patents

Weiguo Zhao holds a patent for a "Polyurethane or polyurethane-urea aqueous dispersion, preparation method therefor, and use thereof." This invention features a self-crosslinkable polyurethane or polyurethane-urea aqueous dispersion. The unique aspect of this dispersion is that the side chains contain non-sterically-hindered siloxy groups. During the drying and activation process, these siloxys hydrolyze and crosslink, enhancing the cross-linking density. This results in significantly improved heat resistance, humidity resistance, and other properties of the adhesive produced from this dispersion. The aqueous dispersion itself exhibits good stability, making it suitable for high-quality paints and sealants, especially adhesives.
