Hydroxypropyl Starch Ether (HPS) is a premium, highly etherified white fine powder derived from natural plant sources. Engineered without the use of plasticizers, this versatile additive is specifically designed to enhance the performance of cement-based and lime-calcium-based putty and mortar products. By improving workability and ensuring structural integrity, it serves as an essential component for professional-grade building materials.
When utilized in conjunction with methyl cellulose ether, HPS significantly increases coating thickness and promotes a robust internal structure. This synergy results in superior crack resistance and sag resistance, making it an ideal choice for both internal and external wall putty powders. Beyond construction, its exceptional thickening and stabilizing properties make it highly effective in the textile, daily chemical, and oil drilling industries.
