CAS No. 40623-75-4
Structural Formula:
Properties:
AA-AMPSA 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-AMPSA
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-AMPSA 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-AMPSA 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-AMPSA 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.
