AA/HPA, Acrylic Acid-hydroxypropyl Acrylate Copolymer
Properties:
Dispersant IR-225 is a copolymer of polyacrylic acid and hydroxypropyl acrylate. AA/HPA copolymer has good scale inhibition and dispersion properties to calcium phosphate and calcium carbonate. AA/HPA has good dispersion properties to ferric oxide sludge, clay, and grease.
AA/HPA copolymer (IR-225) can be used under a high pH situation. It has good compatibility with other organophosphines and BTA. Dispersant IR-225 can effectively withhold sediments of zinc salt and calcium phosphate. AA/HPA copolymer has good scale inhibition and dispersion properties under high temperature and alkaline situations.
CAS No.: 55719-33-0

Usage:
AA/HPA copolymer (IR-225) can be used in circulating cool water system in the situation of alkaline and excess of phosphate. AA/HPA can be used as a scale inhibitor and dispersant for a heater, none-column evaporator boiler, circulating cool water and oilfield dirty refilling water with the high calcium content.
The dosage of 10~30mg/L is preferred. Dispersant IR-225 can be built with organophosphines to form a full organic alkaline formula.
Package and Storage:
Normally in 200 kg net plastic drum, the IBC drum can also be used as required. Storage for one year in room shady and dry place.
