2014-01-04 09:30:49

Copolymer of phono and carboxylic acid (POCA)


Through the introduction of phosphonic group into carboxylic group , POCA 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 . POCA has advantages in wide range of water quality , chemical stability , strong chlorine tolerance , etc. POCA can be used as scale and corrosion inhibitor in circulating cool water system and oilfield refill water system.
