Acrylic Acid-2-Hydroxypropyl Acrylate Copolymer (T-225)
Acrylic Acid-2-Hydroxypropyl Acrylate Copolymer (T-225) is a copolymer of polyacrylic acid and hydroxypropyl acrylate. It has good scale inhibition and dispersion properties to calcium phosphate and calcium, making it suitable for use in circulating cooling water under alkaline conditions and with the presence of more phosphate. T-225 has a CAS No. 55719-33-0, an appearance of colorless to light yellow viscous liquid, and a solid content of 30.0% min with free monomer (as AA) at 0.5% max. It is also known as AA/HPA, 2-Propenoic acid 2-hydroxypropyl ester polymer with 2-propenoic acid, Acrylic Acid-2-Hydroxypropyl Acrylate Copolymer (T-225), Acrylic Acid-2-Hydroxypropyl Acrylate CopolyMer (T-225), and T-225.
CAS No. 55719-33-0
T-225 is an advanced copolymer of polyacrylic acid and hydroxypropyl acrylate. It offers exceptional scale inhibition and dispersion properties against key antagonists such as calcium phosphate, calcium carbonate, ferric oxide sludge, clay, and grease. This product can be used in high pH situations with excellent compatibility with other organophosphines and BTA. Additionally, T-225 provides optimum results with its ability to withhold sediments of zinc salt and calcium phosphate effectively. Its performance remains even under high temperatures and alkaline conditions for outstanding results.
|Appearance||Colorless to pale yellow transparent liquid|
|Solid content, %||30.0 min||30.0 min|
|Free monomer (as AA ), %||0.5 max||0.5 max|
|pH(1% water solution)||7.5±1.0||2.5±0.5|

T-225 can be used in circulating cool water systems with high alkalinity and phosphate levels. It is an effective scale inhibitor and dispersant for heaters, non-column evaporators, boilers, circulating cool water and dirty refilling oilfields with a calcium content. The dosage should be between 10-30mg/L for optimal results. T-225 can also be combined with organophosphines to form a full organic alkaline formula.
Packaging and storage instructions for T-225
As per customer requirements, include 200L plastic drums or IBC (1000L) containers. The product must be stored in a dry, shaded area for up to one year to maintain its efficacy.
