Polyepoxysuccinic Acid (PESA) is a phosphorus-free, nitrogen-free green environmentally friendly scale and corrosion inhibitor. It demonstrates exceptional scale inhibition and dispersion performance for calcium carbonate, calcium sulfate, and barium sulfate, significantly outperforming traditional organic phosphonate scale inhibitors. When compounded with phosphonates, it produces synergistic effects while providing excellent corrosion inhibition, making it an ideal choice for a new generation of multifunctional water treatment chemicals.
High Efficiency Scale Inhibition: Particularly suitable for high alkalinity, high hardness, and high pH water conditions
Environmentally Friendly & Biodegradable: Fully complies with green chemistry requirements
Excellent Compatibility: Good compatibility with chlorine and other water treatment chemicals
Multifunctional: Combines scale inhibition, dispersion, and corrosion inhibition properties
Synergistic Effects: Enhanced performance when used in combination with phosphonates
