ACUMER™ 3100 terpolymer contains three functional groups: strong acid (sulfonate), weak acid (carboxylate) and a nonionic that provide optimal dispersancy for most particules under
a broad range of operating conditions:
• ACUMER 3100 carboxylate groups are most strongly attracted to particles surfaces, allowing strong dispersant absorption onto particles.
• ACUMER 3100 sulfonate groups are only weakly attracted to the particle surface and retain some residual negative charge to provide repulsion preventing particles from
aggregating into larger particles which can settle and deposit on tube surfaces and low flow areas.
• ACUMER 3100 nonionic groups further enhance dispersancy by providing steric repulsion between particles.
Dispersancy
Performance
ACUMER™ 3100 polymer is an exceptional dispersant, especially for dispersing both dried and hydrated iron oxide, hydroxyapatite and calcium carbonate. It is also an excellent
stabilizer for corrosion inhibitors such as phosphate, phosphonates and zinc.


Suggested
Applications
• Dispersant and stabilizer that can be used in cooling water programs ACUMER 3100 terpolymer excels in harsh cooling water conditions, such as extremely
high or low Ryznar Indexes, high iron concentrations, high levels of zinc or phosphate added as treatment to the system. ACUMER 3100 is particularly recommended in
advanced all-organic programs. The product can maintain excellent heat transfer by its exceptional dispersancy and, in addition, will help corrosion inhibition by controlling film
formation of the organic corrosion inhibitors onto metal surfaces.
• Control of boiler sludge
ACUMER 3100 terpolymer is the product of choice for boiler water treatment formulations as it provides unsurpassed control of boiler sludge. The polymer makes it possible to
easily transport iron with calcium and phosphate containing sludges for removal during blowdown. Superior iron oxide dispersant, ACUMER 3100 is particularly recommended to
control hydrated iron oxide in condensate return line.
Thermal/Hydrolytic
Stability
ACUMER™ 3100 terpolymer is highly resistant to breakdown in aqueous solution under conditions of high temperature, pressure and pH. As a safety measure ACUMER 3100 is
not recommended for boilers operating at pressure greater than 900 psig. ACUMER 3100 is very resistant to hydrolysis as well. The product does not lose its
performance capability after storage at pH 13.5 for 6 months at ambient temperature. Approval ACUMER™ 3100 is TUV approved for use in boilers under the reference: 06-KG-66

Applications

Dispersant and stabilizer for use in all cooling water programs

ACUMER 3100 is particularly recommended in advanced all-organic programs. The product will maintain excellent heat transfer by its superior dispersancy and, in addition, will help corrosion inhibition by controlling film formation of the organic corrosion inhibitors onto metal surfaces.

ACUMER 3100 Terpolymer
The Anti-Scale Deposition for
“Stressed” Cooling Water Conditions
ACUMER 3100 is a carboxylate/sulfonate/nonionic functional terpolymer. It is a superior dispersant and
stabilizer for use in all cooling water programs. When other polymers fail under “stressed” conditions,
ACUMER 3100 will maintain excellent heat transfer and low corrosion rates in the system. “Stressed” conditions are found in cooling waters containing high levels of calcium, iron, phosphate, or zinc either, naturally occurring in the feedwater or introduced via treatment. These circulating waters may have either a very
low or a very high Ryznar Index since ACUMER 3100 performs well in waters with either a scaling or corrosion problem. It is an excellent anti-scalant agent and, also, a stabilizer for corrosion inhibitors such as
phosphate and zinc.
ACUMER 3100 will disperse particulate matter containing calcium, iron, and kaolin and prevent their adhesion to heat transfer surfaces. This terpolymer also prevents the precipitation of phosphonates, and zinc
in circulating water with high amounts of calcium, iron, or alkalinity, to allow controlled film formation of these corrosion inhibitors at the metal surface and, thus, maintain low corrosion rates.

CHEMISTRY AND MECHANISM OF ACTION
ACUMER 3100 terpolymer contains three functional groups: strong acid (sulfonate), weak acid (carboxylate), and a nonionic that provide optimal dispersancy for most particulates under a broad range of operating conditions.
Among the three functionalities, ACUMER 3100 carboxylate groups are most strongly attracted to particle surfaces, allowing strong dispersant adsorption onto particles. ACUMER 3100 sulfonate groups are only
weakly attracted to the particle surface and retain some residual negative charge to provide repulsion of similarly charged particles in the cooling water circuit. This repulsion prevents particles from aggregating into
larger particles which can settle and deposit on tube surfaces and low flow areas. ACUMER 3100 nonionic groups further enhance dispersancy by providing steric repulsion between particles.
This multi-functional action contrasts sharply to other dispersants, such as polyacrylic acid or polymethacrylic acid, having only carboxylate functionality which can become strongly attached to certain particles, leaving little residual negative charge available to provide dispersancy. Other polymers, such as SSMA
can provide better dispersancy than PAA or PMAA on some particle substrates, but do not have the nonionic group which allows ACUMER 3100 terpolymer to function on a broader range of potential foulants.
