Properties
PCA has good dispersion property for scale of calcium carbonate and calcium phosphate in circulating cool water system. It has good scale inhibition for barium sulfate, strontium sulfate and silica scale. PCA has advantages in thermal stability and strong chlorine tolerance. PCA can be used as scale and corrosion inhibitor in circulating cooling water system and oilfield refill water system. PCA has better performance than acrylic products in paper making mill, ceramic industry and etc.
Storage
Storage in shady room and dry place.
Application
When used alone, the dosage of 5-20 mg/L is preferred. It can also be used together with organophosphines, copolymer, zinc salt or BTA
Appearance
Colorless to pale yellow aqueous solution
