MA/AA (Copolymer of Maleic and Acylic Acid) CAS 26677-99-6 MA/AA is a low molecular weight polyelectrolyte, a copolymer of maleic anhydride and acrylic acid. MA/AA has good dispersant performance against carbonate and scale inhibition for phosphate. MA/AA has good thermal stability, can be used under high temperature (300 centigrade). MA/AA has good compatibility when used together with other agents. MA/AA is widely used in low-pressure boiler, centralized heating, centralized air-conditioner and circulating cool system. MA/AA can also be used as chelating dispersants in woven and dyeing fields. Specification of MA/AA: items: Water treatment agent Accessory detergent Appearance of MA/AA: Clear brown liquid Amber transparent liquid Solid content of MA/AA: 48 % min 50 % min Free monomer of MA/AA (MA): 9.0 % max 5.0 % max Density of MA/AA (20centigrade): 1.18 min 1.18min pH of MA/AA (1% solution) 2.0~3.0 2.0+/-1.0 Usage of MA/AA: MA/AA is used in circulating cool water system, medium or lower pressure boiler and distillation system in which high temperature is usually encountered. MA/AA can be used alone or together with other organic phosphates. When used together, the dosage of 2-10mg/L is preferred. The dosage for use as woven & dyeing and accessory detergent should be determined by experiments. Package and Storage of MA/AA: Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for one year in room shady and dry place. Safety Protection of MA/AA: Acidity, Avoid contact with eye and skin, once contacted, flush with water
