LANDU NOVASTAR Hydroxypropyl Starch Ether
What is Hydroxypropyl Starch Ether?
Starch ether, a polysaccharide compound derived from natural plants, shares an identical chemical structure and exhibits properties similar to cellulose. It is a finely powdered, white substance produced by modification, extensive etherification, and subsequent drying, free from plasticizing agents. Combined with cellulose ether, starch ether is compatible with neutral and alkaline systems and most additives in gypsum and cement products. The rapid thickening ability of starch ether comes from dosages typically between 0.01%-0.1%. This small amount, however, delivers powerful water control performance and anti-slip ability.

Basic Functions of Hydroxypropyl Starch Ether
- Moisture Control Ability
The high content of hydroxypropyl in starch ether gives the system stable hydrophobicity, turning free water into bound water, which plays a good role in water retaining ability. HPS starch ether is also responsible for providing workability, longer open time, and adjustability time.
- Excellent Thickening Effect
The substitution of a hydroxypropyl group increases the expansion in water and compresses the space for particle flow, thus increasing viscosity and thickening. This property also contributes to anti-slip performance.
- Improved Thixotropy
With HPS starch ether as an additive, the mortar can be easily cut off without sticking to the scraper. Then the viscosity increases as the external force is withdrawn. Therefore, HPS Starch ether-based mortar can be easier to pump and apply.

Featured Applications
Plaster and Skim Coat
In plaster and skim coat mortar, fluidity and sag resistance are mutually restricted. The increase in fluidity often leads to a decrease in sag resistance. However, NOVASTAR HPS starch ether could balance these two properties of plastering and putty mortar, especially in machine-spraying plaster requiring high flowability and anti-sagging performance.
Tile Adhesive
NOVASTAR HPS starch ether can quickly adjust the viscosity of tile adhesive while delivering a durable tile installation, especially for Grade E tile adhesive, which requires an extended opening time of 20 to 30 minutes and tensile strength of 0.5MPa. That’s why NOVASTAR HPS starch ether becomes a critical ingredient in the tile adhesive formula.
EIFS
With a wide applicable temperature ranging from -30℃ to 80℃, NOVASTAR HPS starch ether is suitable for adhesion mortar in the EIFS finish system. It is used to improve water preservation and adhesion while avoiding cracking and shrinkage due to temperature fluctuation.
