- Product Performance
This product has excellent anti-scaling and corrosion-inhibiting effects and good temperature resistance. It can inhibit the formation of carbonate and sulfate scale. In alkaline environments, its anti-scaling and corrosion-inhibiting performance is better than that of other organic phosphonic acid type water treatment agents. It can also be used as an anti-scaling agent for oilfield reinjection water.
