Product Parameters

Product Description:
EDDHA-Na is a kind of efficient dispersant, embrace strong anionic charge. It's stable in chemical performace when under water conditions of heat, pressure and strong acid & alkali. It has good compatability with other components in the formula.

Main Application

1. Used as anti-caking agent: a small amount of antisludging agent can make large scale deposits disperse in aqueous solution. EDDHA-Na destroy the growth of scale, and reduce the speed of scale subsidence. In this way, it reach the inhibition effect.
2. Used as chelating agent: The role of chelation is refers to that the  chelating agent can generate stable water-soluble complexes with metal ions.
3. Used as dispersant: Dispersion effect makes the coalescence crystals and other particle becoming more difficult.

Important Notice

We normally list 2 years as the shelf life in our COA, the real shelf life is actually much longer than 2 years if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials).
