Hydroxypropyl starch ether(HPS)
Hydroxypropyl starch ether is a non-ionic starch produced by the etherification reaction of propy lene oxide with starch under alkaline conditions, also known as starch ether. Starch ether can impart unique properties to cement and gypsum-based products. it has a similar chemical structure to HPMC, which not only provides functions similar to HPMC, but also has good compatibility with other building additives. When it is used with hydroxypropyl methyl cellulose, it can play a better role in thickening, have a better crack resistance, and improve workability. In addition, by adding starch ether, the cost of the mortar formulation can be significantly reduced.

Product Feature
The performance of starch ether in dry mortar is as follows:
1. Starch ether, due to its special chemical structure, can effectively prevent the hanging phenomenon of thick mortar and is
especially suitable for tile adhesives. it can significantly improve the product's anti-sagging and anti-slip properties in the tile adhesive system.
2. Adding an appropriate amount of starch ether to the mortar can prolong the open time of the mortar.
3. It has a fast-thickening function for mortar,which can improve the rheology of mortar such as sprayed mortar and plaster mortar.
Usage
Pre-mix evenly with other dry powder components before packaging. Mix and use on-site according to the recommended amount of water.
The recommended addition amount is 0.1%-0.3% of the cementitious material, which must be pre -tested according to the raw materials and construction specifications before use.
Packaging
25 kg / 55 lb paper bag
Storage condition
Store products with original packaging in a dry, clean environment and away from heat sources. This product is not easy to lose efficacy, but it is hydrophilic-based. If the storage environment is poor, it will slowly absorb moisture. It is recommended to follow the first-in-first-out principle when using it. The packaging must be tightly sealed to prevent moisture intrusion if not finished use.
