Hydroxyethylidene Diphosphonic Acid

Hydroxyethylidene Diphosphonic Acid or HEDP acts as an organo phosphonate compound with multi-functional properties such as deflocculation, sequestration, and super threshold inhibition in a single active ingredient.

The product is commercially produced in 50%/ 60% concentration, serving as a scale and synergistic corrosion inhibitor for inhibiting iron rust and mineral scale in pipes of cooling circulation water units and boilers. It also acts as a metal chelate agent for colour fixing and bleaching in textile and also functions as a complexing agent for electron plate and scale cleaning agent for metals.

Key Attributes and Benefits:

• Acts as a metal chelate agent
• Helps as an effective scale inhibitor

HEDP are available in salts of sodium compounds such as

• HEDP 2Na (Hydroxyethylidene Diphosphonic Acid - Disodium salt),
• HEDP 4Na (Hydroxyethylidene Diphosphonic Acid - Tetra sodium salt) etc.
