CAS No. 55719-33-0
Structural Formula:
Properties:
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, it has good scale inhibition and dispersion
properties under high temperature and alkaline situations.

Usage:
T-225 can be used in circulating cool water system in situation of
alkaline and excess of phosphate. It can be 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 to form full organic alkaline formula.
Package and Storage:
Normally In 200kg net Plastic Drum, IBC drum
can also be used as required. Storage for one year in room shady
and dry place.
