Hydroxypropyl Starch Ether for Tile Adhesive & Dry Mix Mortar
Hydroxypropyl Starch Ether is a high-performance modified starch ether widely used in dry mix mortar systems as a rheology modifier, anti-sagging additive, and workability enhancer. In modern construction materials, it plays a critical role in improving application stability, consistency, and construction efficiency.
At InnoNew, our Hydroxypropyl Starch Ether is specially developed for cement-based and gypsum-based systems, offering excellent anti-slip performance, optimized rheology control, and superior compatibility with cellulose ether and polymer-modified mortar formulations.
Designed for demanding construction environments, our HPS solutions are widely used in tile adhesive, wall putty, gypsum plaster, skim coat, self-leveling mortar, and EIFS systems.
What Does Hydroxypropyl Starch Ether Do in Mortar Systems?
In dry mix mortar formulations, Hydroxypropyl Starch Ether functions primarily as a rheology modifier and structural stabilizer.
Unlike cellulose ether, which mainly provides water retention, HPS focuses on:
- Anti-sagging performance
- Structural build-up
- Application consistency
- Slip resistance
- Workability optimization
Its unique rheological behavior helps mortar maintain stability after application while still allowing smooth troweling and easy spreading.
This balance is especially important in vertical tile adhesive applications and gypsum-based finishing systems.
