Hydroxypropyl Starch Ether (HPS) is a nonionic and highly stable substitute ether bond. This means it remains intact during hydrolysis, oxidation, dextrinization, and cross-linking reactions. Essentially, HPS, a chemically modified starch ether, functions primarily as a thickener and texturing agent in cement or gypsum-based mortar products.

Notably, HPS is an economical material, easily achieving the desired thickening effects. In wet mortar applications, it provides non-sag properties, enhances anti-slip, improves workability, and maintains low stickiness.

• Enhances sag resistance & anti-slip
• Optimizes rheological behavior, especially flow characteristics and workability
• Improves adhesion strength
• Increases mortar yield
• Cost-effective, delivering desired thickening effects at minimal dosages.

In lacquer putty, HPS enhances the application and thixotropy of the putty, facilitating a smooth operation.

HPS boosts mortar adhesion, balances open time, and provides anti-slip properties for tile adhesives. Additional benefits include excellent fluidity, film-forming characteristics, weak retrogradation, and stable viscosity.

HPS significantly improves the rheology of plaster, reduces sagging in subsequent plaster applications, and minimizes shrinkage and crack formation.
