As a kind of water based rust inhibition detergent, the antirust detergent contains powerful surfactants and rust prevention agents. Appearing as a yellow, clear and evenly mixed liquid, our antirust detergent is a stable, low foaming solution that contains no harmful nitrites. The cleansing capability of our rust inhibition detergent is due to the use of surfactants or surface active agents which lower the interfacial tension between water or grease and the metal surface it clings to. Simply put, the antirust detergent removes water, grime, grease, soil, or dirt by separating it from any surface it stays on. In addition to cleansing, the surface active agents have other functions such as wetting, dispersing, emulsifying, and solubilising. In fact, the grime-removal process of surfactant is not that straightforward, and needs the help of external mechanical force. Other than cleansing, our low-foaming antirust detergent contains powerful rust proofing agents that form a dense, firm film on the metal surface for rust protection.

In-process rust prevention, or rust protection before preservation for ferrous metals.
Method of Use
1. Suitable for use at temperatures between 45°C and 75°C. Apply the low-foam antirust detergent by spray, brush or dip.
2. Please note that the low-foam antirust detergent is sold in its concentrated form. Be sure to add 3% to 5% of water to dilute the detergent concentrate according to actual cleansing applications
3. Deionized water should be used if precision parts need to be washed. Care should be taken to check the pH value, hardness, and content of chloride and sulphate if industrial water is used which might affect the stability and detergency of the antirust detergent.
4. Keep in check the pH value, appearance, and degree of pollution of water-soluble detergent to ensure the cleansing results. Remember your rust prevention washing solution should be restocked with detergents or replaced every so often.
Packaging: 25kg/pail, 50kg/pail, 180kg/pail. Custom packaging is available.
