PESA is a phosphorus‑free and nitrogen‑free “green” multi‑component scale and corrosion inhibitor. It exhibits excellent scale‑inhibiting and dispersing performance against calcium carbonate, calcium sulfate and barium sulfate in water, and its scale‑inhibiting effect is superior to conventional organic phosphonate scale inhibitors. It delivers remarkable synergistic effect when compounded with phosphonate salts. It also provides certain corrosion‑inhibiting property as a multi‑functional scale inhibitor.
Molecular Formula: HO(C₄H₂O₅M₂)nH
Relative Molecular Weight: 400‑1500
Note: M = Na⁺, H⁺ or K⁺; R = H or C1‑4 alkyl; n = 2‑10
