Our Modified Hydroxypropyl Starch Ether (HPS) is a premium, highly etherified white fine powder derived from natural plant raw materials. Specially engineered for high-performance construction materials, this additive is formulated without plasticizers, ensuring an eco-friendly and stable chemical composition. It serves as a critical admixture for cement-based, lime-calcium-based, and gypsum-based putty and mortar products, providing exceptional compatibility with various building additives.
By integrating Hydroxypropyl Starch Ether into your formulations, you can significantly enhance workability, improve internal structural integrity, and achieve superior crack and sag resistance. When used in synergy with methyl cellulose ethers, it optimizes the thickness of the application layer and reduces the overall requirement for expensive cellulose ethers, making it a cost-effective solution for professional-grade wall putty and decorative mortars.

Frequently Asked Questions
It is primarily used as an admixture in cement-based, gypsum-based, and lime-calcium-based wall putties and mortars to improve workability, reduce cracking, and prevent sagging.
While it can reduce the amount of cellulose ether required, it is highly recommended to use it in conjunction with methyl cellulose ether to maximize thickness and internal structure.
The recommended dosage is generally between 0.3-0.5%o, though we advise buyers to conduct their own tests to determine the specific dosage for their particular formulation.
Yes, it is used in the oil drilling industry to help stabilize boreholes and improve conditions such as anti-sloughing and the flocculation of drilling cuttings.
HPS helps extend the open time, meaning the material remains workable for longer, allowing technicians more time to adjust and smooth the surface before it sets.
No, our Modified Hydroxypropyl Starch Ether is produced from natural plant materials and is strictly formulated to contain no plasticizers.
