Properties
HPAA is chemically stable, hard to be hydrolyzed, hard to be destroyed byacid or alkali, safety in use, no toxicity, no pollution.HPAA can improve zinc solubility. Itscorrosion inhibition ability is 5-8 times better than that of HEDP andEDTMP. When built with low molecular polymers, itscorrosion inhibition effect is even better.
