HPS (Hydroxypropyl Starch)


Hydroxypropyl Starch Ether(HPS) is a nonionic additive derived from natural starch through chemical modification, specifically used in construction applications.
HPS is characterized by excellent thixotropy and workability enhancement—effectively improving the spreading performance of mortars, reducing water loss in thin-layer constructions, and optimizing the cohesive force of fresh mortars without significantly increasing viscosity, making it ideal for tile adhesives, wall putties and other construction mortars.
