Wanhua chemical takes "chemistry, better life" as its corporate mission, and actively responds to the work plan of the 13th five year plan of the state on reducing the total VOCs emission by 10% in 2020. It has jointly launched the "oil to water" revolution of polyurethane waterproof coating with the help of sanjeshu group, a brand green building materials system supplier of a big country.
After five years of research and development, Wanhua chemical and sanjeshu have successfully developed water-based polyurethane resin (PUD) which can be used for waterproofing. The first coating based on waterborne polyurethane resin PUD in the waterproof industry was released on April 15, 2020 at the fortune forum and new product Conference on the waterproof line of three trees, officially announcing the industrialization of waterborne polyurethane waterproof coating. Mr. Lin Dedian, vice president of sankeshu group, Dr. Cai Zhengwei, product director of sankeshu group, etc. attended the conference.

At the meeting, Dr. Cai Zhengwei explained in detail the advantages of the water-based polyurethane waterproof coating of sankeshu. Sanjeshu water-borne polyurethane waterproof coating not only solves the pain points of traditional oil-borne polyurethane, such as high VOC, high odor and difficult construction, but also has excellent mechanical properties. Its main properties are superior to those of other water-borne polyurethane systems, especially the aging time of artificial climate is up to 2500h, which meets the requirements of single-layer roof waterproof materials.
