KH-GR802 gypsum retarder is a new generation of retarder product with excellent characteristics such as low dosage, good retarding effect, and good dispersibility. It is synthesized from a variety of amino acids and has a special molecular structure of protein-type retarder. It is adaptable to various types of gypsum and can adjust the setting time of gypsum according to needs, without affecting the strength of hardened gypsum.

Product Characteristics：

·High Retardation: It can provide good retarding effects at low dosages, and the setting time is linearly controllable.

·High Compatibility: It has excellent adaptability with various gypsum systems and is well compatible with other functional additives.

·High Dispersion: It has excellent dispersibility, and is easy to dissolve in water, easy to mix evenly with no extra steps.

·Strength Stability: It does not affect the post-mechanical properties of the gypsum-based material, ensuring stable strength development.

·Eco Friendly: Does not contain harmful substances, safe and environmentally friendly.

KH-GR802 has excellent compatibility and is suitable for various natural and industrial by-product gypsum-based material systems. Such as in:

·Gypsum-Based Self-Leveling Mortar

·Plastering gypsum, masonry gypsum, painting gypsum, jointing gypsum, gypsum putty, etc.

·Gypsum precast parts, gypsum blocks, gypsum boards, and other products

·Other gypsum application fields

Instructions for Use：

1.Before use, KH-GR802 needs to be mixed evenly with other dry powder components. The construction mixing and application should be carried out according to the specific requirements of the different fields of application.

2.The recommended dosage of KH-GR802 is between 0.05% and 0.25% of the binders. The optimal amount should be determined through experimental trials based on factors like the mineral composition of the gypsum resources, the quality of calcination, storage time, etc.

Shelf Life：

1.The shelf life is 12 months from the date of production. If the shelf life has expired, testing and verification must be carried out before use.

2.Store in a well-ventilated and dry place. Measures should be taken to prevent moisture. Avoiding direct sunlight. Store separately from flammable, combustible, reducing agents, acids, and alkalis.After opening, it should be used promptly. If not all of it is used, it should be sealed promptly to prevent it from absorbing moisture and becoming spoiled.
