WN-721
is a new type of alkali-resistant amino acid-based gypsum retarder,
specifically designed for natural gypsum and industrial by-product
gypsum. At an extremely low dosage, this product delivers excellent
retarding effects with a clear and controllable linear relationship
between dosage and retarding time—allowing customers to precisely adjust
the setting time as needed. Meanwhile, it has minimal impact on the
long-term strength of gypsum products.
- Natural gypsum
- Industrial desulfurized gypsum
- Phosphogypsum
- Other industrial by-product gypsum
✅ High-Efficiency Retardation at Low Dosage
An ideal retarding effect can be achieved with a dosage of only 0.08-0.1%.
✅ Linear Controllability
The retarding time and dosage show a clear linear relationship, enabling precise adjustment.
✅ Strong Adaptability
Excellent compatibility with various types of gypsum.
✅ Minimal Impact on Strength
Has very little effect on the long-term strength of gypsum products.
✅ Good Compatibility
Well-compatible with gypsum additives such as water reducers, defoamers, and stabilizers.
✅ Uniform Dispersion
Ensures uniform and stable mixing with excellent dispersibility.
✅ Stable Quality
Reliable and stable production process ensures high consistency in product quality.
Recommended Dosage: 0.08-0.1% (based on the weight of gypsum).
Notes:
- Differences in the mineral composition of gypsum resources across regions may affect the setting time of gypsum.
- A trial mixing test should be conducted when using the product for the first time to determine the optimal dosage.
- The dosage can be adjusted according to actual needs to control the setting time.
This product exhibits good compatibility with common gypsum additives, including water reducers, defoamers, and stabilizers.
- Packaging Specification: 25 kg/double-layer moisture-proof packaging (customized packaging available).
- Storage Conditions: Store in a cool, dry place; protect from moisture and high temperatures.
- Special Requirements: The product has slight hygroscopicity and must be sealed to prevent caking.
- Shelf Life: 12 months from the date of production.
- Handling After Expiration: If the product exceeds its shelf life, it must be tested and verified before use.
