Advantages

At low dosage, it can play a good retarding effect, and the setting time is controllable.	Suitable for natural and industrial by-product gypsum such as phosphogypsum and desulphurized gypsum, and compatible with various other additives;
Good dispersion, easy to dissolve in water, easy to mix evenly, do not increase the process.	With the increase of retarder dosage, the setting time is relatively slow and average longer, and the setting time is easier to control.

Application
    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

Uses

• 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.

• 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

• 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.

• Store in a well-ventilated and dry place. Measures should be taken to prevent moisture. Avoiding direct sunlight.
