Usage:

HPMA is usually used together with organic phosphonate at dosage of 1-15ppm for circulating cooling water system, oilfield fill water, crude oil dewatering and low-pressure boilers. HPMA has good scale inhibition (98%) and scale stripping properties.
When used together with zinc salts, it can effectively inhibit carbon steel corrosion..
