Acrylic TerpolymerZEELCHEM™ 7000 · Manufacturer & Supplier
Acrylic Terpolymer is a tri-functional carboxylate–sulfonate–non-ionic polymer for the harshest water. ZEELCHEM™ 7000 controls calcium phosphate, silica and metal oxide deposits in zero liquid discharge (ZLD) cooling towers running at 8–12 cycles of concentration, where standard copolymers fail.

How Acrylic Terpolymer Works
Carboxylic groups
Complex calcium strongly for threshold scale inhibition.
Sulfonic groups
Disperse iron and phosphate colloids electrostatically and sterically.
Non-ionic groups
Keep the polymer extended in high-salinity water above 5,000 ppm TDS.
Key Benefits
- Works where copolymers fail: calcium phosphate, silica and metal oxides
- Built for ZLD towers at 8–12 cycles and high skin temperatures
- Prevents precipitation at calcium hardness above 2,000 ppm
- Stable against oxidizing biocides and thermal breakdown
- Effective in high-salinity water above 5,000 ppm TDS

What makes ZEELCHEM™ 7000 a tri-functional terpolymer?
It combines carboxylic acid groups for scale inhibition, sulfonic acid groups for phosphate and iron dispersion, and non-ionic groups for stability under extreme stress.
Which systems need an acrylic terpolymer?
ZLD cooling towers, all-organic corrosion and scale programmes, geothermal steam reinjection, and high-recovery RO units with high silica and hardness.
What is the recommended dosage?
Continuous dosing of 10–25 ppm active in high-stress cooling towers, and 15–40 ppm in geothermal or steam-flood reinjection.
How does the non-ionic group help?
It forms steric barriers that prevent precipitation at calcium hardness above 2,000 ppm and at high ionic strength.
What are the active content and specific gravity?
At least 40% active, with a specific gravity of 1.15–1.25 g/cm³ and a pH of 2.5–4.5 (1% aqueous).
Is the terpolymer compatible with chlorine and biocides?
Yes. It is stable against oxidizing biocides and thermal breakdown.
What packaging is available?
60 kg carboys, 250 kg virgin HDPE drums, 1,250 kg IBC totes and bulk tankers.
What is the shelf life?
24 months in original sealed containers, stored dry and ventilated at 5–40 °C.
What safety precautions apply?
Safety goggles, chemical-resistant nitrile gloves and protective clothing.
Do you provide COA and MSDS with every batch?
Yes. Every ZEELCHEM™ 7000 consignment ships with a batch Certificate of Analysis, and the TDS and 16-section GHS Safety Data Sheet are available on request.
