Product Overview

Hydroxypropyl starch ether is a modified starch derivative that undergoes a highly etherified reaction to enhance its functional properties. Unlike conventional starches, it is produced without plasticizers, ensuring its purity and effectiveness as an industrial additive. This material is specifically designed to improve the performance of cement-based, gypsum-based, and lime-calcium-based products, making it a critical component in construction and building materials.

Key Features and Benefits

Hydroxypropyl starch ether stands out due to its exceptional performance characteristics, which include:

• Fast Thickening Ability: It rapidly increases the viscosity of aqueous solutions, enhancing the workability of construction materials.
• Medium Viscosity with Water Retention: The material maintains optimal moisture levels, preventing premature drying and ensuring consistent application.
• Low Dosage Requirement: A minimal addition (0.3-0.5%) achieves significant improvements in material properties, reducing costs and waste.
• Enhanced Sag Resistance: Particularly beneficial in tile adhesives and wall putty, it prevents slumping and ensures even distribution.
• Improved Workability: Facilitates smoother application and reduces labor intensity during construction processes.
• Extended Opening Time: Allows for greater flexibility in construction timelines without compromising material integrity.
