GYPSUM RETARDER

Gypsum retarder is a multifunctional retarder for powder. A white or light yellow powder formed by spray drying using advanced techniques. It can control the growth rate of hydrated crystals in gypsum based products, significantly adjust the setting time and improve the working performance, and perform better in neutral and alkaline environments.

Product feature

Good retarding effect, low dosage, high cost performance, good adaptability, good adaptability to all kinds of gypsum powder has good fluidity, in gypsum mortar, easy to mix with other powder, good stability, easy storage and so on. Gypsum retarder can be combined with most gypsum additives (water reducer,stabilizer, defoamer, etc.) .

Application Scope

Civil engineering

Construction engineering

Traffic roads

Special engineering

1. High-Efficiency Retardation & Precise Control

Significantly extends setting time by precisely regulating the growth rate of hydrated gypsum crystals, optimizing the workability window for operations like mixing and finishing.

2. Low-Cost & High Cost-Effectiveness

Achieves excellent retarding performance at low dosage, substantially reducing raw material costs and offering an outstanding return on investment.

3.Universal Compatibility

Compatible with various gypsum sources (industrial desulfurized gypsum, phosphogypsum, natural gypsum) and suitable for all major gypsum-based products (plasters, self-leveling compounds, putties, boards, etc.), particularly effective in neutral/alkaline formulations.

4.Enhanced Workability & Flow Properties

Exhibits excellent powder flow characteristics for easy dry-mix blending; improves mortar workability and application smoothness.

5.Strong Compatibility & Storage Stability

Demonstrates excellent synergistic compatibility with common gypsum additives (water reducers, stabilizers, defoamers) without adverse effects. Features low moisture content (≤3.0%) ensuring long-term storage stability and consistent performance.

6.Advanced Manufacturing & Quality Assurance

Produced via spray-drying technology for homogeneous particle size, superior solubility, and dispersion. Defined technical specifications (Appearance, pH 7-13, Bulk Density 400-800 g/L, Moisture) guarantee batch-to-batch consistency.
