The water based anti-rust liquid is by medium of water, made by adding multiple inhibitors and additives of high performance. The product is a kind of brown and transparent liquid with good stability, reliability and environmental-friendliness. By producing very thin protective film on the metal surface, it can effectively inhibit metals from corrosion, especial to cast iron, and provides the cleaning and lubricant functions as well. For short-term processing application, the validity of corrosion protection is up to 30 days, while for long-term application and matching with VCI paper or VCI plastic film, the validity is over one year.
