Packaging and Storage

Packaging
25Kg paper-plastic composite bag, lined with moisture-proof film. Can provide ton bag packaging to meet large-scale demand.
Storage
Store in a dry, ventilated, and cool place, avoid moisture and direct sunlight. The shelf life is 12 months, and it should be used as soon as possible after opening.

Main Mechanism of Action

Dispersion Effect
By reducing the surface tension between particles, prevent cement particles, dyes and other aggregation, and improve the uniformity of dispersion.
Chelation Effect
Chelate with metal ions to improve their solubility and stability.
Water Reduction Effect
Reduce water consumption, improve the compactness and strength of materials.
Bonding Effect
As a binder, it enhances the bonding force between particles.

Method of Use

Concrete Additives
The recommended dosage is 0.2% -0.5% of the weight of cement, and the specific ratio can be adjusted according to project requirements. It can be directly mixed with cement, water, and aggregate for use.
Fertilizer Additives
Add 0.5% -1% of the fertilizer weight to improve particle strength and uniformity.
Other Applications
When used as a dispersant or binder, it can be dissolved in water and added proportionally.
Notes
It is recommended to conduct a small test first to ensure compatibility and effectiveness with other ingredients. • To prevent moisture from clumping, if there is a slight clumping, it can be properly screened and treated without affecting the use effect.
