Project Description

CAS No.: 67953-76-8

Molecular Formula: C2H8-xO7P2Kx


HEDP Kx is the potassium salt of the equivalent of DEQUEST 2010. This HEDP potassium salt has better dissolution ability than that of sodium salt under a neutral condition.

HEDP Kx is a good scale inhibitor for calcium carbonate. It can be used in metal corrosion inhibitor, an antifouling agent of swimming pool, metal cleaning, volume cleaning, iron dust controlling, metal pretreatment, low-pressure boiler water treatment and circulating water treatment, etc.
