T-225 is copolymer of polyacrylic acid and hydroxypropyl acrylate. It has good scale inhibition and dispersion properties to calcium phosphate and calcium carbonate. It has good dispersion properties to ferric oxide sludge, clay and grease. T-225 can be used under high pH situation and has good compatibility with other organophosphines and BTA. T-225 can effectively withhold sediments of zinc salt and calcium phosphate scale. It has good scale inhibition and dispersion properties under high temperature and alkaline situations.

T-225 is suitable for circulating cool water system in situation of alkaline and excess of phosphate. It is mainly used as scale inhibitor and dispersant for heater, none-column evaporator boiler, circulating cool water and oilfield dirty refilling water with high calcium content. The dosage of 10~30mg/L is preferred. It can be built with organophosphines into a full organic (alkaline) formula.
Avoid contact with eye and skin. In case of contact, flush with water immediately.
25kg/200kg net in plastic drum or as required. Storage for twelve months in shady room with good ventilation.
