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.

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 200L Plastic Drum, IBC, or as per required.
Storage for ten months in room shady and dry places.
