Product Features:

XL TREAT-7620 is a low molecular weight polyelectrolyte, a copolymer of maleic anhydride and acrylic acid. It has good dispersant performance against carbonate and scale inhibition for phosphate. It has good thermal stability, can be used under high temperature (300℃). XL TREAT-7620 has good compatibility when used together with other agents. XL TREAT-7620 is widely used in low-pressure boiler, centralized heating, and centralized air-conditioner and circulating cool system. It can also be used as chelating dispersants in woven and dyeing fields.
