CAS No.: 55719-33-0 
Structural Formula:

Product performance:
T-225 is copolymer of acrylic acid and hydroxypropyl acrylate, it has good scale inhibition and dispersion properties against calcium carbonate and calcium sulfate, and also has good dispersion against Fe2O3
sludge
clay and oil dirt. T-225 can be used under high PH value and has good compatibility with other organic phosphates and BTA, can effectively withhold sediments of zinc salt and calcium phosphate, it has good scale inhibition and dispersion properties under high temperature and alkaline condition.
