PUBLISH:admin READ:1322

Chemical Name:Phosphinocarboxylic acid copolymer 50%

Abbreviation:S-PCA

CAS Number:40623-75-4


Application Notes:

S-PCA is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid. Due to including carboxylic group (scale inhibition and dispersion) and sulfonic acid group (strong polarity) in this copolymer, S-PCA 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. S-PCA 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.


Recommended Uses:

S-PCA 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. S-PCA can also be used as dyeing auxiliaries for textile.
