High Performance Gypsum Retarder China Factory and Reliable Suppliers
Our high-performance Gypsum Retarder is a specialized additive designed to optimize the setting time of gypsum-based cementitious materials. By precisely controlling the hydration process, it prevents premature solidification, ensuring that gypsum slurries maintain their plasticity and fluidity for extended periods, which is critical for professional construction and architectural applications.
Engineered with advanced amino acid salts and modified chemical components, this retarder enhances the workability of painting gypsum, bonding gypsum, and gypsum putty. It ensures a smooth, crack-free surface finish and improves the overall decorative properties of the hardened body, providing superior sound absorption and thermal insulation for modern building projects.

Frequently Asked Questions
Q: What is the primary function of a Gypsum Retarder in construction?
The primary function is to slow down the setting speed of gypsum after it is mixed with water, maintaining the slurry's plasticity for a longer period to allow for proper application and shaping.
Q: Which specific gypsum products can this retarder be used in?
It is ideal for painting gypsum, bonding gypsum, gypsum putty, and various lightweight gypsum-based building materials.
Q: How does the retarder affect the final properties of the hardened gypsum?
It improves the surface smoothness and prevents cracking during the drying process, while preserving the material's natural sound absorption and thermal insulation.
Q: What are the storage requirements to ensure product shelf life?
Store in a cool, dry place away from direct sunlight. Avoid storage under pressure. Unopened packaging remains stable for several years.
Q: Is the amino acid modified salt compatible with other additives?
Yes, it is designed to work within standard cementitious systems, although we recommend a small-scale test to ensure compatibility with specific proprietary additives.
Q: What is the recommended mesh size for optimal mixing?
Our product features a screening rate of ≥95% within the 180-200 mesh range, ensuring rapid dissolution and uniform distribution in the gypsum mix.
