Properties & Key Features
KR-400 is a multifunctional deposit control agent designed for flexibility in water treatment formulations.
Its typical technical specifications are as follows:
Property Specification
Appearance Clear colorless to pale yellow liquid
Solid Content 50.0% min
Density (20°C) 1.21 – 1.26 g/cm³
pH (as it) 2.0 – 3.0
Viscosity (25°C) 250 – 550 cps
Key performance features include:
General Scale Control: Effective for controlling general calcium phosphate and calcium carbonate fouling.
Formulation Support: It serves as a building block to improve the performance of phosphate, polyphosphate, phosphonate, and zinc-based water treatment formulations.
Oxidizing Biocide Stability: It is not affected by chlorine or other oxidizing biocides under normal use conditions.
Multifunctional Capabilities: Formulations with KR-400 can provide phosphate inhibition, phosphonate stabilization, iron oxide dispersancy, calcium carbonate inhibition, and zinc stabilization.
Applications & Usage
KR-400 is used in several industrial water treatment applications:
Cooling Water Systems: Used for scale inhibition, particularly for CaCO₃ scale, in open recirculating cooling circuits.
Oil Field Water Treatment: Applied to prevent scale in both the formation and production equipment.
Boiler Water Treatment: Used as a dispersant for boiler sludge control.
Usage Suggestion: When used alone, the preferred dosage is 10-30 mg/L. It is also suitable for use in process water and similar applications.
