I. Performance and Applications
AA-AMPS is a co-polymer of acrylic acid and 2-acrylamide-2-methylpropanesulfonic acid (AMPS). Due to the presence of carboxylic acid groups and highly polar sulfonic acid groups in its molecular structure, which exhibit good scale inhibition and dispersing properties, it improves calcium tolerance and has a significant scale inhibition effect on calcium phosphate, calcium carbonate, and zinc scale in water, preventing the deposition of iron oxide, especially showing a high scale inhibition rate for calcium phosphate. It also has excellent dispersing properties. When combined with organophosphorous compounds, its synergistic effect is significant. It is particularly suitable for water quality with high pH, high alkalinity, and high hardness, making it one of the ideal scale inhibitors and dispersants for achieving high concentration ratios.
AA-AMPS can also be used as a textile printing and dyeing auxiliary agent; and as a scale inhibitor for pulp in paper-making systems.

III. Usage Instructions
AA-AMPS can be used in combination with organophosphonates and zinc salts, and is suitable for pH conditions of 7.0–9.5.
IV. Packaging and Storage
AA-AMPS is packaged in plastic drums, each containing 25 kg, 200 kg, or 250 kg, or as per user requirements. The shelf life of AA-AMPS is twelve months.
V. Safety and Protection
AA-AMPS is acidic. Take precautions during handling to avoid contact with skin and eyes. If contact occurs, rinse thoroughly with plenty of water.
