JTB- 850 is a tartaric acid retarder.
Type: Tartaric acid
Solid content (%): ≥ 98%
Active substance content (%): ≥ 98%
This product is suitable for retarding the setting of sulfoaluminate cement. It has the following characteristics and advantages.
For Production:
Stable properties and easy to store
Stable storage: Cement mortar materials can be stored for extended periods after mixing.
For Formulation:
The recommended dosage range has no effect on strength.
For Construction:
Effectively extends setting time, facilitating construction.
This product is suitable for mortar and concrete systems that require high fluidity retention , especially for sulfur-aluminum cement systems, such as bearing mortar, self-leveling compound, and quick-repair concrete.
The recommended dosage of this product in various systems is 1-5‰ of the cementitious material.
The optimal dosage needs to be determined through testing.
This product is packaged in paper bags, 25kg/bag (larger bags can also be provided upon special requirements).
This product is recommended to be stored in an environment of 0~30℃ and used within 6 months; there is a risk of clumping.
