Gypsum Retarder
- White, light yellow or light gray powder
- ≤3.0
- ≤5.0
- 700±100
- ≥6.0
A gypsum retarder is a chemical additive used in the construction industry. It controls and delays the setting time of gypsum-based materials, such as gypsum powder and plasterboard. This provides more time for processing and reduces the risk of premature setting, thereby preventing surface irregularities or defects.
- Excellent retarding effect with low dosage.
- Good adaptability to various plasters and gypsum-based systems.
- As the retarder dosage increases, the setting time of gypsum prolongs steadily, which helps to improve the quality stability of gypsum products.
- Minor side effects on gypsum strength.
- Odorless, non-toxic, and pollution-free.Shorten the initial-to-final setting time interval of gypsum mortarXuhai gypsum retarders effectively shorten the interval between initial and final setting times, thereby preventing plastic cracking caused by excessively long setting durations.
