KH-GR802E General Purpose Gypsum Retarder
✓ Low dosage with good retarding effect
✓ Linearly controllable setting time
✓ Compatible with various gypsum systems
✓ Recommended dosage 0.05%-0.25% of binders
Product Preview
KH-GR802E is a new-generation protein-based gypsum retarder synthesized from a variety of amino acids. It has low dosage, good retarding effect, good dispersibility and broad adaptability to gypsum systems.
The product can adjust gypsum setting time according to application needs without affecting the strength of hardened gypsum. It is suitable for natural and industrial by-product gypsum-based material systems.

High Retardation at Low Dosage
KH-GR802E provides good retarding effects at low dosage and the setting time is linearly controllable.
High Compatibility
It adapts to various gypsum systems and is compatible with other functional additives after testing.
Stable Strength
The product does not affect the later mechanical properties of gypsum-based materials, supporting stable strength development.
Gypsum-Based Self-Leveling Mortar
Used to adjust setting time and maintain workable application windows.
Plaster and Putty Systems
Suitable for plastering gypsum, masonry gypsum, painting gypsum, jointing gypsum and gypsum putty.
Gypsum Products
Applicable to gypsum precast parts, gypsum blocks, gypsum boards and related gypsum fields.
What dosage is recommended?
The recommended dosage is 0.05%-0.25% of the binders.
Does it affect gypsum strength?
The existing product information states that it does not affect post-mechanical properties and supports stable strength development.
Is it easy to disperse?
Yes. It has good dispersibility, dissolves in water and mixes evenly without extra steps.
Store KH-GR802E in sealed packaging in a cool, dry, ventilated place. Protect from moisture and package damage. The shelf life is 12 months from production; test before use after expiry.
Mix KH-GR802E evenly with other dry powder components before use. Start with 0.05%-0.25% of binders and determine the optimum dosage through trials based on gypsum mineral composition, calcination quality and storage time.
