Properties and Applications of KR-499 Acrylic/Sulfonic Terpolymer

KR-499 is a low molecular weight, multifunctional acrylic/sulfonic terpolymer designed for deposit control in industrial water treatment, particularly in open evaporative cooling systems. Its key properties and applications are summarized below.

Properties & Key Features

Property Detail

Appearance Clear, pale yellow liquid

Solid Content 48.0% min

Total Phosphorus (as PO₄³⁻) 1.0% min

Density (20°C) 1.15 g/cm³ min

pH (1% water solution) 1.5 - 3.5

Multifunctional Deposit Control: Offers effective control of calcium carbonate and calcium phosphate scale, along with dispersancy for iron oxide and particles.

Corrosion Inhibition: The product also provides corrosion inhibition properties.

Halogen Stability: It maintains its performance in the presence of halogens (like chlorine), which are commonly used as biocides in cooling water systems.

Low Phosphorus Content: Helps to keep high levels of orthophosphate in solution, which can reduce the need for additional phosphorus-based additives.

Cost-Effective Formulating: Can replace existing copolymers in formulations, allowing for simplification and potential cost reduction.

Applications

Primary Application: Used in open evaporative cooling water systems.

Other Suitable Systems: Can also be used in oilfield water injection, boiler water treatment, and dust-collecting water systems in industries such as petrochemical, chemical, metallurgy, and power. Note: this broader industrial application is sourced from general information for a similar terpolymer.

Combination with Other Agents: KR-499 has good compatibility with other common water treatment agents like polyphosphates, zinc salts, and organophosphonates.

Usage Suggestion: It is recommended to avoid direct contact with eyes and skin. In case of contact, flush immediately with plenty of clean water.
