Acrylic Acid-2-Hydroxypropyl Acrylate Copolymer (T-225)

CAS No.  55719-33-0

Structural Formula:



T-225 is copolymer of polyacrylic acid and hydroxypropyl acrylate, which has good scale inhibition to calcium phosphate and calcium carbonate; good dispersion properties to ferric oxide sludge, clay and grease. T-225 can be used in high pH condition and has good compatibility with other organophosphines and BTAT-225 can effectively withhold sediments of zinc salt and calcium phosphate, it has good scale inhibition and dispersion properties under high temperature and alkaline situations. T-225 is mainly used as scale dispersant in a variety of circulating cooling water systems(especially high turbidity, operating environment with dust pollution).

T-225 can be used in circulating cooling water system in situation of alkaline and excess of phosphate. It also can be used as scale inhibitor and dispersant for heater, none-column evaporator boiler, circulating cooling water and oilfield dirty refilling water with high calcium content. The dosage of 10~30mg/L is preferred. Usually, T-225 can be built with organophosphines to form full organic alkaline formula.
