Aspect Clear solution* Chemical nature Acrylic homopolymer Grade Partial Na salt (20% neutralized)

ACUMER 1100 is a low molecular weight polyacrylate with a selected molecular weight around 2000 to optimize the anti-scale performance through at least three mechanisms: • Solubility enhancement by threshold effect, which reduces precipitation of low solubility inorganic salts (calcium carbonate in particular). • 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.

A Low molecular weight polyacrylate homopolymer (4500 Mw) for general purpose scale inhibition
Description
ACUMER 1100 is low molecular weight polyacrylate for general purpose scale inhibition within water systems, providing exceptional efficiency at a low dosage over a wide range of pH, water hardness and temperature conditions.
ACUMER 1100 is a low molecular weight polyacrylate with a selected molecular weight around 4500 to optimize the anti-scale performance through at least three mechanisms:

Dispersing activity, which prevents precipitated crystals or other inorganic particles from agglomerating and depositing on surfaces.
Anti-Precipitation Performance
ACUMER 1100 polymer is a general purpose scale inhibitor as it is effective to prevent scale building in inhibiting precipitation and deposition of calcium carbonate, calcium oxalate, calcium sulfate, barium sulfate, and other low solubility salts.

Applications

Industrial Water Treatment
Scale inhibition in open recirculating cooling circuits (CaCO3 scale in particular).
Dispersant for all types of cooling circuits.
Dispersant for boiler sludge control.
Benefits of ACUMER 1100

Contains no phosphorus, making its use acceptable where legislation requires that discharge waters
Exhibits exceptional stability in the presence of hypochlorite.
Shows good anti-scaling efficiency at low dosage over a wide range of pH, water hardness and temperature conditions.
Offers a strong dispersant activity contrarily to phosphonates.

MATERIAL SAFETY DATA SHEETS
Rohm and Haas company maintains Material Safety
Data Sheet (MSDS) on all of its products. These contain important information that you may need to protect your employees and customers against any known health and safety hazards associated with our products. We recommend you obtain copies of MSDS for our products from your local Rohm and Haas technical representative or the Rohm and Haas company. In addition, we recommend you obtain copies of MSDS from your suppliers of other raw materials used with our products.
In some instances, blends of phosphonates or phosphate esters with ACUMER polymers are better anti-precipitants than either alone. Figure 9 demonstrates the synergistic behavior of ACUMER 1100/ACUMER 1110 and phosphonate for calcium carbonate inhibition; the dotted lines plot the additive effects and the solid lines the actual effects of the blends.
4. Inhibition of BaSO4 Precipitation (Figure 10)
BaSO4 scale is particularly difficult to remove and consequently prevention is critically important, especially in off-shore oil wells and papermaking applications. ACUMER 1000/ACUMER 1020 polymers (Mw 2000) are particularly effective in a typical 16-hour duration test and show more efficient inhibition than ACUMER 1100/ACUMER 1110 (Mw 4500) polymers. ACUMER 1000/ACUMER 1020 polymers also show better inhibiting activity than a competitive sodium polyacrylate, a phosphonate, or a phosphate ester.
If longer times (64 hours) are allowed for precipitation, ACUMER 1100/ACUMER 1110 (Mw 4500) are more effective than ACUMER 1000/ACUMER 1020 (Mw 2000).
5. Overall Anti-Precipitation Performance
The actual choice between the two molecular weight polymers depends on the test conditions, although generally ACUMER 1000/ACUMER 1020 (Mw 2000) are the most effective polymers. At high Ca+2 concentration and high temperature, ACUMER 1000/ACUMER 1020 would be expected to perform better than ACUMER 1100/ ACUMER 1100 considering the comparative solubilities versus Ca+2 concentration and temperature in Figure 3.
MODIFICATION OF CaSO4 AND CaCO3 CRYSTALS (Figures 11 and 12)
The photomicrographs in Figures 11 and 12 show the dramatic crystal distortion effects of ACUMER 1000/ ACUMER 1020 and ACUMER 1100/ACUMER 1110 on CaSO4 and CaCO3. The normally long and regular CaSO4 crystals are fractured and distorted when formed in the presence of ACUMER 1000/ACUMER 1020 polymers. CaCO3 crystals are normally large and well formed, but are smaller and more irregular when formed in the presence of ACUMER 1100/ACUMER 1110.
