Miqi’s water-based rust inhibitor can provide short-term rust protection for ferrous metals in the application of cutting fluid, cleaning agent and other water-soluble liquids. The correct use of these rust inhibitors can not only ensure effective rust protection during processing, but also provide short-term protection between processes. AANTA-BOR series of water-soluble rust prevention agents are based on the combination of different amines and different meta-carboxylic acids, and provide the best combination of different boron content and different types of amines to facilitate the selection of formulation engineers to meet the processing needs and local regulatory requirements. They not only have excellent corrosion resistance to ferrous metals, but also have excellent solubilization, wettability and hard water stability, which can effectively extend the service life of cutting fluid。
