| Abstract: | One-component polyurethane waterproofing coating was prepared by MDI, polyether polyols and other agents. The article discussed influences of the content of --NCO, the ratio of poly three alcohol to polyether glycol, the content of latent curing agent, catalyst and acid agent on curing and physical and mechanical properties of the coating. The coating prepared by the best formula met the requirements of GB/T 19250---2003. |
