Product Description

Product Description

Gypsum retarder is a powder with good fluidity and is not easy to agglomerate. Adding gypsum retarder to gypsum dry-mixed building materials can inhibit the hydration process of hemihydrate gypsum and prolong the setting time. Before using gypsum retarder, the initial and final setting time of gypsum powder should be measured and then the appropriate type of retarder should be selected.

Detailed Photos

1). Stable retarding effect: prepared by single amino acid polymerization to ensure the consistency of polypeptide unit structure, the retarding time is linearly related to the dosage, and the performance stability is better than hydrolyzed protein products.
2). High environmental protection: biodegradable (28-day degradation rate ≥ 65%), non-toxic and non-irritating (LD50>2000mg/kg), in line with green building materials standards
3). Wide adaptability: suitable for a variety of gypsum-based building materials such as desulfurized gypsum and phosphogypsum (such as gypsum board, self-leveling, and plaster), and has little effect on strength
4). Easy to use: the powder has good fluidity and is easy to mix evenly. The recommended dosage is 0.1-0.3%.

Application

Gypsum mortar
Gypsum putty
Gypsum-based self-leveling
Gypsum decorative lines
Prefabricated gypsum components
Gypsum blocks

Usage & Precautions:

1). Dosage:
Add gypsum retarder powder to the powder and mix well for use. The recommended addition amount is 0.05%-0.5% of the cementitious material, and it should be tested in advance according to the raw materials and performance requirements.
2). Storage and transportation:
It should be stored and transported in the original packaging and kept cool and dry. During production and use, once the original packaging is opened, resealing measures must be taken to avoid moisture intrusion.
3). Expiry time:
Keep in a cool and dry place for one year. For products that have exceeded the shelf life, verification tests should be performed before use.
