ACUMER 2000 is an excellent phosphate and zinc stabilizer and dispersant of inorganic particulates for anti-scale/anti-corrosion cooling water treatment formulations.
ACUMER 2000 copolymer combines two functional groups: strong acid (sulfonate) and weak acid (carboxylate) that provide optimal anti-scale/dispersant efficiency through the different mechanisms
ACUMER 2000 polymer is designed to provide superior stabilization of calcium phosphate.
ACUMER 2000 also demonstrates excellent stabilization of zinc and calcium carbonate.
In addition ACUMER 2000 is a strong dispersant in keeping the silt and commonly encountered inorganic particules suspended and in preventing their settling out onto heat transfer surfaces.
Phosphates and zinc stabilizer for anti-scale / anti-corrosion water treatment formulations.
ACUMER 2000 enhances corrosion inhibition and acts as an excellent silt dispersant.
Advantages of ACUMER 2000:
Prevent the formation of deposits on heat transfer surfaces,
Prevent inorganic and sedimentation fouling,
Stabilizes corrosion inhibitors such as zinc, phosphates, and phosphonates,
NSF-60 certification for RO potable water,
Inhibits precipitation of calcium, magnesium, and iron salts.
Benefits of ACUMER 2000:
Excellent scale inhibition for a variety of applications including cooling circuits, boilers and RO units.
Exhibits excellent thermal and chemical stability and can be used and stored over a broad range of temperatures and pH's.
This stability enables the formulator to manufacture one-package treatments at high pH for maximum shelf life.
Provides superior iron tolerance when most of the commercially available polymers are desactivated in the presence of soluble iron in the system.
Keeps surfaces clean for maximum heat transfer and corrosion resistance.
Usage of ACUMER 2000:
ACUMER 2000 can be used as a scale inhibitor for circulating cool water and boiler water, for phosphate, zinc ion and inorganic minerals in particular.
When used alone, the dosage of 10-30 mg/L is preferred.
When used in other fields, the dosage should be determined by experiment.

ACUMER 2000 carboxylate-sulfonate copolymer dispersant can effectively stabilize calcium phosphate in the formula containing phosphate.
ACUMER 2000 can also stabilize zinc in a formula containing zinc.
ACUMER 2000 can disperse inorganic microparticles without pH influence.
ACUMER 2000 carboxylate-sulfonate copolymer is an effective dispersant in all organic water treatment formula, ACUMER 2000 can be used as a dispersant for minerals, a stabilizer for calcium phosphate.
Chemistry and Mode of Action of ACUMER 2000:
ACUMER 2000 copolymer combines two functional groups: strong acid (sulfonate) and weak acid (carboxylate) that provide optimal anti scale/dispersant efficiency through the following different mechanisms:
-Solubility enhancement by threshold effect, which reduces precipitation of low solubility inorganic salts.
-Crystal modification, which deforms the growing inorganic salt crystal to give small, irregular, readily fractured crystals that do not adhere well to surfaces and can be easily removed during cleaning operations.
-Dispersing activity, which prevents precipitated crystals or other inorganic particules from agglomerating and depositing on surfaces.
The sulfonate groups increase the negative charge of the carboxylate groups adsorbed onto particles and, by then, reinforce the repulsion between the particles, preventing them from aggregating into larger particles which can settle and deposit on tube surfaces and low flow areas.
Stabilization / Dispersancy Performance of ACUMER 2000:
ACUMER 2000 polymer is designed to provide superior stabilization of calcium phosphate.
