KR-2000 is a high-performance carboxylate-sulfonate copolymer, specifically an acrylic acid-AMPS (2-acrylamido-2-methylpropanesulfonic acid) copolymer. It functions primarily as a scale inhibitor and dispersant in industrial water treatment.
Core Performance & Functions
KR-2000 demonstrates strong scale inhibition and dispersion capabilities, particularly effective against several key challenges in water systems:
Scale Inhibition: It effectively inhibits the formation of calcium phosphate (Ca₃(PO₄)₂) and calcium carbonate (CaCO₃) scales. It is noted to be an excellent stabilizer for calcium phosphate and a good inhibitor for calcium carbonate.
Dispersancy: The product excels at dispersing inorganic microparticles, such as iron oxide, clay, and silt, keeping them suspended in the water to prevent deposition.
Zinc Stabilization: In formulations containing zinc, KR-2000 acts as an efficient stabilizer for zinc ions, preventing them from precipitating.
| Items | Index |
|---|---|
| Appearance | Colorless to pale yellow transparent liquid |
| Solid content, % | 42.0-44.0 |
| Density (20℃), g/cm3 | 1.15min |
| pH (as it) | 3.8-4.6 |

Note on Solid Content: One source specifies a solid content of 42.5-43.5%, while most indicate a range of 42.0-44.0%. The slightly higher range may refer to a specific batch or grade.
Primary Applications & Usage
KR-2000 is widely used in industrial water treatment applications, including:
Circulating Cooling Water Systems: Used for scale and deposit control in cooling towers.
Boiler Water Treatment: Helps maintain clean heat transfer surfaces.
Formulations with Phosphate or Zinc: Particularly valuable in phosphate-based treatment programs and zinc-containing formulations to stabilize these key components.
Recommended Dosage: When used alone, the typical dosage is 10 to 30 mg/L. For other applications as a dispersant, the dosage should be determined through experimentation.
Storage and Handling
Packaging: Available in 25kg bags, 200L plastic drums, 1000L IBC containers, or ISO tanks.
Shelf Life: Recommended storage for 10 to 12 months in a cool, dry, and shaded room.
Safety: The product is weakly acidic. Avoid contact with skin and eyes. In case of contact, flush thoroughly with plenty of clean water.
