Properties

AA/AMPS is a copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid. Because of 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 particularly suitable to be used in water quality of high pH, high alkaline and high hardness, it is one of the ideal scale inhibitor and dispersant on high concentration index.

Storage

Storage in shady room and dry place.

pH of 1% solution

3.0 max; 3.5-4.5

Application

AA/AMPS can be used as scale inhibitor and dispersant in open circulating cooling 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.

Appearance

Colorless to light yellow viscous liquid

Description

AA/AMPS is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid (AMPS).
