High-Performance Gypsum Retarder Powder With Low Dosage, Strong Retarding Effect

Gypsum retarder is a multifunctional powder additive used in gypsum-based building material systems to control setting time and improve working performance. It is a white or light yellow powder produced by advanced spray-drying technology. It can effectively control the growth rate of hydrated crystals in gypsum-based products, significantly adjust the setting time, and perform well in neutral and alkaline environments.

Gypsum retarder offers a strong retarding effect at low dosage, with good cost performance and wide compatibility with different kinds of gypsum powder. It also has good fluidity, making it easy to mix with other powders in gypsum mortar. In addition, it provides good stability and is convenient for storage. Gypsum retarder can also be used together with most gypsum additives, such as water reducers, stabilizers, and defoamers.
