WheChemical TA is a high-purity tartaric acid powder used as an efficient setting retarder in gypsum and gypsum-based dry-mix systems. It provides precise control of hydration kinetics, allowing formulators to extend open time and improve workability while maintaining mechanical strength and surface quality. TA is particularly suitable for gypsum formulations requiring predictable retardation, clean finishing behavior, and stable performance across varying temperatures and production conditions.
