ZhiFormix™ GR-01 is a high-efficiency set-control additive developed for gypsum and calcium sulfate-based formulations.
It is designed to extend working time and provide a predictable setting profile, helping formulators balance processing time, application efficiency and final performance.
GR-01 is especially suitable for gypsum dry-mix systems where setting control, workability and strength retention must be carefully balanced.
Helps adjust gypsum setting time according to the required processing window.
Provides additional time for mixing, application and finishing.
Designed to control setting while minimizing unwanted impact on final performance.
Suitable for formulation development with superplasticizers, cellulose ethers and defoamers after compatibility testing.
GR-01 is recommended when the formulation needs a controlled and repeatable working-time window rather than simply maximum retardation.
The development target is to balance:
according to production and application requirements.
during mixing, placement and finishing.
without unnecessary loss of hardened strength.
