Dispersants
Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid
Copolymer (AA/AMPS)
CAS No.: 40623-75-4
Structural Formula:
Properties:
AA/AMPS is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid (AMPS). Due to including carboxylic group (scale inhibition and dispersion) and sulfonic acid group (strong polarity) in this copolymer, AA/AMPS has high calcium tolerance and good scale inhibition for calcium phosphate, calcium carbonate and zinc scale. When built with organophosphines, the synergic effect is obvious. AA/AMPS is suitable to be used in water quality of high pH and high alkaline, it is one of the ideal scale inhibitor and dispersant on high concentration index.
Specification:
| items | Index |
| Appearance | Colorless or light yellow viscous liquid |
| Solid content | ≥40% |
| Free monomer (as AA) | ≤0.8% |
| Density (20℃) | ≥1.15 g/cm3 |
| pH(1％ solution) | 3.5-4.5 |

Usage:
AA/AMPS can be used as scale inhibitor and dispersant in open circulating cool water system, oilfield refill water system, metallurgy system and iron & steel plants to prevent sediment of ferric oxide. When built with organophosphorines and zinc salt, the suitable pH value is 7.0~9.5. AA/AMPS can also be used as dyeing auxiliaries for textile.
Package and Storage:
Normally In 250kg net plastic drum. IBC drum can also be used as required. Storage for ten months in room shady and dry place.
