Key Advantages

Extended Setting Time

Highly effective setting delay for the hydration process of gypsum achieved even at minimal doses

No reduction of final strength

Unlike with several fruit acid based retarders, it won’t reduce in the final strength of gypsum based products

Q&A

Q1: What is Gypsum Retarder Powder based on amino acids?

A: It is a gypsum retarder developed from amino acids containing –NH₂ and –COOH groups, which provide unique chemical properties and stability. This formulation retards gypsum setting while maintaining the final strength of the product consistently.
Q2: Can it be used with other additives?

A: Yes, our gypsum retarder is compatible with additives like JTBON Foaming Agent and superplasticizers, which are essential for gypsum board production. Feel free to contact us for more details on Foaming Agents and superplasticizers.
Q3: What testing is required before use?

A: Prior to use, conduct thorough testing including compatibility trials with other additives, performance assessments, and dosage calibration tests. These evaluations ensure that the retarder functions correctly and meets the specific requirements of your gypsum-based application.
