Amino Acid Gypsum Retarders: Superior Performance for Modern European Construction

In the production of high-quality gypsum plasters, screeds, and moulds, precise control over the working time is essential. Gypsum retarders are crucial additives that delay the hydration of hemihydrate gypsum, allowing for sufficient time for application, finishing, and intricate detailing.

While various retarders exist, not all are created equal. Many traditional options force a trade-off between workability and the final strength of the product. At Yuanlian Chemical, we champion Amino Acid-Based Gypsum Retarders – a technological leap that delivers effective retardation without compromising performance, specifically engineered for the demanding standards of the European construction industry.

The Limitations of Conventional Gypsum Retarders

To understand the advantage of amino acid technology, it's important to recognize the shortcomings of older retarder types:

1. Protein-Based Retarders (e.g., Animal Glue):

   • Drawbacks: Inconsistent performance, susceptibility to spoilage and unpleasant odours, and a significant negative impact on the final strength of the gypsum product.

2. Citric Acid & Citrates:

   • Drawbacks: Although strong and cost-effective, they drastically reduce the compressive and flexural strength of set gypsum (often by 30% or more) and can cause surface dusting and stickiness.

3. Polyphosphates:

   • Drawbacks: Can have compatibility issues with other admixtures, potentially affecting the fluidity of the gypsum slurry. Overuse may also lead to efflorescence.

The Common Problem: The "Strength Dilemma" – achieving the necessary workability often comes at the direct expense of the gypsum's mechanical properties and durability.

Amino Acid Technology: A Leap Forward in Performance

Amino acid-based retarders are synthesized through molecular engineering to interact with gypsum crystals in a more controlled and gentle manner. This represents a significant advancement over conventional products.

Key Benefits for Manufacturers:

• Minimal Strength Loss: The primary advantage. By adsorbing onto crystal surfaces and moderating growth rather than disrupting it, our retarders preserve the gypsum's intrinsic strength. This results in superior final products with enhanced durability and lower risk of failure.

• Exceptional Consistency & Reliability: With a defined molecular structure and high purity, our retarders offer predictable performance batch-after-batch, unaffected by variations in water quality or ambient temperature. This is critical for ISO-certified production and quality control.

• Broad Compatibility: They work synergistically with superplasticizers, water retention agents, and other admixtures, making them ideal for complex, high-performance gypsum formulations like self-leveling screeds and high-strength casting plasters.

• Eco-Friendly & Low Odour: Formulated to meet stringent European environmental and safety standards (REACH), our products are non-toxic, contain no formaldehyde, and are virtually odourless, ensuring a better working environment and a greener end-product.
