CAS No.: 40623-75-4
Structural Formula:
Properties:
AA/AMPS is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic
acid (ATBS). 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 twelve months in room shady and
dry place.
