AA/AMPS (Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid)

AA/AMPS --Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer
CAS 40623-75-4

Properties of AA/AMPS:
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 of AA/AMPS:
Appearance Colorless or light yellow viscous liquid
Solid content % 40 min
Free monomer (as AA)% 0.8 max
Density (20 C)g/cm3 1.15 min
pH(1% solution) 3.5-4.5
Viscosity mpa.s 90-200

Usage of AA/AMPS:
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 of AA/AMPS:
Normally In 250kg net Plastic Drum, IBC drum can also be used as required.Storage for ten months in
room shady and dry place.
