Why Michem Leads in Gypsum Retarder Technology
Our R&D team combines deep chemical engineering expertise with real-world construction application experience
Advanced Molecular Engineering
Our modified amino acid technology represents the third generation of gypsum retarders. Unlike traditional citric acid or protein-based retarders, our molecular structure provides linear dosage-response correlation, allowing precise setting time prediction.
Application Engineering Support
Having worked with 500+ gypsum board manufacturers and plaster producers globally, our technical team understands regional raw material variations and provides customized dosage recommendations for your specific gypsum source.
Quality Assurance Protocol
Every batch undergoes 7-point quality testing including HPLC purity analysis, particle size distribution, and setting time verification using standardized gypsum samples. Full traceability from raw material to finished product.
What is Gypsum Retarder?
Gypsum Retarder is a highly efficient gypsum retarder, suitable for various types of gypsum and applications, including handmade plaster, machine plaster, grout, dental plaster, and gypsum blocks. Belonging to the amino acid group, Gypsum Retarder offers unparalleled effectiveness in controlling the setting time of gypsum-based products.Its activity is characterized by the correlation between setting time and dosage, and it is capable of providing excellent performance even at very low dosages
