High-Performance Amino Acid Gypsum Retarder: The Ultimate Guide to Application and Advantages

In the modern construction and building materials industry, controlling the setting time of gypsum is crucial for ensuring project quality and operational efficiency. While traditional retarders like citric acid have been used for years, they often come with a significant drawback: strength loss.

Enter the Amino Acid Gypsum Retarder, a revolutionary chemical additive that offers precise control over hydration without compromising the structural integrity of the finished product.

What is Amino Acid Gypsum Retarder?

Amino acid gypsum retarders are organic compounds synthesized from natural proteins or synthetic amino acids. Unlike inorganic salts, these retarders work through a sophisticated molecular mechanism. The amino acid molecules adsorb onto the surface of hemihydrate gypsum particles, effectively creating a protective barrier that regulates the growth of dihydrate gypsum crystals.

Key Advantages of Amino Acid Retarders

1. Minimal Strength Loss

The most significant advantage over citric acid is strength retention. While citric acid can reduce the compressive strength of gypsum by up to 30%, high-quality amino acid retarders (like those from Yuanlian Chemical) keep strength loss under 5%.

2. High Efficiency at Low Dosage

These retarders are highly effective even at extremely low concentrations (typically 0.05% to 0.3% of the gypsum weight). This high efficiency makes them a cost-effective choice for large-scale industrial applications.

3. Linear Retarding Effect

Amino acid retarders offer a stable and linear dose-response curve. This means manufacturers can precisely predict and adjust the setting time—from 30 minutes to several hours—simply by adjusting the dosage.

4. Excellent Compatibility

They exhibit superior synergy with other common construction additives, including:

• HPMC/HEMC (Cellulose Ethers)

• Water Reducers (Superplasticizers)

• Redispersible Polymer Powders (RDP)

5. Eco-Friendly and Odorless

Produced through advanced synthesis technology, these products are non-toxic, formaldehyde-free, and do not emit the unpleasant odors often associated with crude protein hydrolysates.
