1. Starch ether is a kind of white fine powder made from natural plants through modifying, high etherification reaction, and spray drying. It doesn’t contain any plasticizer or organic solvent.
2. Starch ether can improve the performance and optimize the workability of dry mortar by modifying the thickness and rheology of varied dry mortars based on cement and gypsum.
Starch ether can be used cooperatively with cellulose ether (HPMC, HEMC, HEC, MC) to achieve better function of thickening, cracking resistance, sag resistance, outstanding lubricity, and improve workability. Adding a certain amount of starch ether can reduce the usage amount of cellulose ether, cost can be saved and construction performance can be improved.
