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.

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.
