CP-50 water-soluble anti-rust additive is a ternary organic wet cake with a content of 50%. It is mainly used as a corrosion inhibiting additive for metals in semi-synthetic cutting fluid, fully synthetic slurry, water-based quenching fluid and water-based cleaning agent, automobile antifreeze, antirust water and other water-based products.

CP-50 has good rust resistance, low foaming, good hard water stability.

Depending on the product and the requirements for rust resistance, the dosage in the concentrate can be 2-25%.

When directly preparing rust-proof water, CP-50 can be dissolved in water with triethanolamine and monoethanolamine to make the pH of the 5% aqueous solution 8-10. For example: purified water 50%; CP-50 25%； MEA 12.5%； TEA 12.5%。

The product has good dispersion in water. The recommended addition order in the formula is: first water and then CP-50, stir into a milky white suspension, and then add alkali or alcohol amine, which can accelerate the dissolution of the formula.
