Product Introduction

Hydroxypropyl starch ether (HPS) is a white, fine powder obtained by modifying natural plant-based starch, subjecting it to a high-degree etherification reaction, and then spray-drying; it contains no plasticizers. It is entirely distinct from conventional starch or modified starch.

★ Excellent rapid thickening ability; moderate water-retention properties;

★ Low dosage—only a very small addition is needed to achieve highly effective results;
★ Enhance the material’s resistance to sliding;
★ Improves the processing performance of the material, making operations smoother;
★ Extend the opening hours of the materials.

Technical Indicators

Application Features

Excellent rapid thickening performance; medium viscosity with good water-retention properties.
It requires only a small dosage; even extremely low addition levels can deliver highly effective results.
Enhance the material’s resistance to sliding.
Improve the material’s handling performance to make operation smoother.
Extend the material’s availability.

Recommended application materials

Various interior and exterior wall putty powders (cement-based, gypsum-based, and lime-based);
Various types of tile and stone adhesives;
Various finishing mortars and various plastering mortars;

Application Fields

It can be used as an admixture for cement-based, gypsum-based, and lime-calcium products. It exhibits excellent compatibility with other construction admixtures. When combined with hydroxypropyl methylcellulose ether (HPMC), it provides thickening effects, promotes internal structural development, enhances crack resistance, and improves workability. The addition of modified starch ether can significantly reduce the dosage of HPMC.

Precautions

Recommended dosage: 0.055%–0.1%, which can also reduce the dosage of methyl cellulose ether by approximately 0.1%.
Packaging: 25 kg per bag.
Storage: Store in a cool, dry place. To prevent moisture from penetrating, reseal any opened bags and ensure that stacked packages do not exceed one pallet. Shelf life is no more than one year.

Safety and Environmental Protection

According to the Gefahrstoffverordnung, this product is classified as non-hazardous. Accident prevention rules related to dust protection (VBG No. 119) must be observed. This product is categorized as ST1. A safety data sheet can be provided upon request.
