HPS-hydroxypropyl starch ether
Hydroxypropyl Starch Ether are starch based additives designed for dry mortars in building industry. These starch ethers 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 should be used in combination with cellulose derivatives. It can well perform in neutral and alkaline conditions, and it is compatible with other additives in gypsum or cement based building materials.
General Properties
- Improve sagging resistance/ anti-sagging properties
