24/7 plant operation helps reduce delivery disruptions from seasonal output curbs, supporting on-time fulfillment of orders.
Hydroxypropyl starch ether (HPS) is a white fine powder obtained from natural plants through modification, high etherification, and spray drying, without plasticizer. It is completely different from ordinary starch or modified starch.
Good fast thickening capacity; medium viscosity, with certain water retention.
The dosage is small, and very low dosage can achieve high effect.
Improve the sliding resistance of materials.
Improve the operating performance of materials, making the operation more smooth.
Extend the opening hours of materials.
◆ It is recommended to apply to the following materials:
◆ All kinds of putty powder for interior and exterior walls (cement, gypsum, lime calcium base), various adhesives (ceramic tile, stone).
◆ Various finishing mortar and plastering mortar.
0.05%-0.1%; At the same time, HPMC can be reduced by about 0.1%.
Package: 25 kg/bag.
Storage: It shall be stored in a cool and dry place. The opened packaging bags shall be sealed again to prevent moisture penetration. When stacked, they shall not exceed one pallet; The storage period shall not exceed one year.
According to Gefahrstoffverordnung standard, this product is non-hazardous. The accident prevention rules related to dust protection (VBG No. 119) must be observed. This product is classified as ST1. Safety data sheet can be given as required.
| Grade | Hydroxypropyl Content wt% | Feature |
|---|---|---|
| InseSTAR™ SE-314 | 14-16 | Strongest anti-slip resistance |
| InseSTAR™ SE-318 | 18-20 | Balancing sag resistance and smooth workability with extended open time |
| InseSTAR™ SE-322 | >22 | Stable rheology, anti-segregation capability, and superior alkali resistance |
It can be used as an additive for cement-based products, gypsum-based products, and lime-calcium products. It has good compatibility with other building additives. When used together with hydroxypropyl methyl cellulose (HPMC), it can play a thickening role, promote internal structure, and have better crack resistance and improve workability. The amount of HPMC can be obviously reduced by adding modified starch ether (HPS).
