What is HPS
Hydroxypropyl Starch Ether is a white (colorless) powder with good fluidity. It has good water solubility, when in an aqueous solution is transparent and colorless with good stability.
This product finds application in a variety of industries including adhesives, cement and gypsum based products, coating or organic liquids for building materials. It can play a better thickening effect, with better crack resistance and improve workability.
Appearance
Starch ether is mainly used for hand or machine spraying mortar, tile adhesive mortar, caulking materials and adhesives, and masonry mortar with cement and gypsum as the cementitious materials. Starch Ether cement- and gypsum-based products with distinctive qualities.
HPS can effectively prevent the hanging phenomenon of thick layer of mortar, which has a good improvement effect on the sliding of the tile, the hanging of thick layer and other undesirable phenomenon. It can enhance the bonding strength between the aggregates.
The Starch Ether has a fast thickening function for mortar, which can improve the rheology of spray mortar and plaster mortar.
The Starch Ether can effectively prevent the stratification/segregation of the mortar, which can be well used in self-leveling mortar.
