WheChemical ST 600 is a modified hydroxypropyl starch developed for cementitious and gypsum-based dry-mix systems that require higher viscosity build-up, enhanced thickening efficiency, and improved structural stability in the fresh mortar. As a non-ionic starch ether, ST 600 delivers strong rheology control, improved water retention, and excellent suspension stability while maintaining reliable processing characteristics. Compared to lower-viscosity grades, ST 600 provides increased body and cohesion, making it especially suitable for formulations where sag resistance, shape stability, and controlled flow behavior are critical.
