product application

Cement Mortar

Coatings

Hydroxypropyl starch ether (HPS) is widely used in cement-based mortar systems to improve water retention and enhance workability. It helps prevent rapid water loss, ensuring sufficient hydration of cement and reducing shrinkage. HPS also increases the open time, improves adhesion to substrates, and provides better sag-resistance in vertical applications.

In water-based coatings, HPS works as a rheology modifier and stabilizer. It helps maintain uniform viscosity, improves brushability and leveling, and enhances the suspension of pigments and fillers. HPS also contributes to reducing splash and improving the smoothness and appearance of the coating surface.
