Colymer™ SWR5200

ColymerTMSWR5200 is the patent technology of Van Entek Enterprises LTD., based on Dow's high-quality substrate product research and development of general scale inhibitor dispersant.

It is especially suitable for reverse osmosis system with high content of barium, strontium, barium sulfate and strontium sulfate. It can effectively prevent scaling in a wide concentration range of scaling substances.

ColymerTM SWR5200 scale inhibitor is a non-phosphorous, degradable and harmless chemical, in line with strict emission environmental regulations.


Product Features:

l  Effective control of inorganic scaling in a large concentration range with a maximum allowable value LSI 3.2 without acid addition

l  Effective control of scaling tendency of calcium sulfate, barium sulfate and strontium sulfate in large concentration range: CaSO4 the concentration is allowed to reach 10 Ksp( solubility product); BaSO4 the concentration is allowed to reach 2500 Ksp( solubility product); SrSO4 Concentration allowed to reach 1200 Ksp( solubility product)

l  Excellent performance in high salt content and high recovery systems

l  Suitable for all major reverse osmosis membranes

l  pH of raw water is effective between 5-10

l  Compliance with drinking water production standards (ANSI/NSF60 certification)

l  Excellent solubility and stability


Physical and chemical indicators:

l  Appearance: Clear light brown liquid

l  Chemical properties: polymers

l  pH :9.0-11.0(5x concentrate);8-11.0(standard solution)

l  Density :1.25±0.10(5x concentrate);1.05±0.05(standard solution)


Packaging specifications:  20 kg barrel.

Storage conditions:

Avoid direct sunlight and store at room temperature (freezing may occur when the temperature is below 4℃ without affecting use after thawing)


The dosage was calculated according to the raw water quality analysis report. the scaling tendency of the reverse osmosis system can be effectively controlled within the recommended dose range.

Security considerations:

If necessary, we can provide the material safety form (MSDS) of the product.
