PAA
Product Description
Polyacrylic Acid (PAA)
CAS No. 9003-01-4
Structural Formula:
Properties:
PAA is innoxious and soluble in water. It can be used in situations of alkaline and high concentration without scale sediment. PAA can disperse the microcrystals or microsand of calcium carbonate, calcium phosphate and calcium sulfate. PAA is used as scale inhibitor and dispersant for circulating cooling water system, papermaking, weave, dyeing, ceramic, painting, etc.
