Description
performance
HPAA in pH7 - 9, Ca2+ water, Zn2+ generation of 1:1 chelates to form a layer of protective film on the surface of the metal, so the formula to add Zn 2+, while the inhibition effect is high, if the formula HPMA (NC-303) or NC-309, while protective film will be more dense and uniform, so this product is usually associated with Zn2+ compound used as inhibitor, because it contains a phosphine group and a carboxyl group, hydroxyl group, so it is a good inhibitor.
