Dr. Liang Zhang, Nouryon Chemicals (Shanghai) Co., Ltd., Shanghai, China

In this paper, the necessity of modifying the properties of mortar with polymer and the importance of hydrophobicity for drymix products are discussed. Hydrophobic agents in powder form usually used in the dry mortar market are also introduced and their existent issues are described. The author summarizes a series of experiments in Elotex R&D center in Switzerland and Elotex Shanghai Technical Center, as well as in cooperation with China Building Materials Academy to test the performance of mortars with a silane based powder, ELOTEX® SEAL80.
Based on this research, the author gives an outlook onto applications in China using this technology.
