At present, metal materials and products between the working procedure and long time storage transport, mostly apply rust prevention oil. However, the subsequent process needs to be degreased, but it is quite difficult to remove the RP oil. It is of great significance to develop water-based corrosion inhibitor because of the increasing tension of oil resources and environmental awareness and the existence of oil which is not easy to decompose.

Water-based RP liquid can replace mechanical oil as the main RP oil, but also eliminate the traditional oil removal, phosphating and other process, both save energy, and reduce the operating cost, but also avoid the waste discharge caused by environmental pollution, can replace RP oil and phosphating liquid.

All kinds of metal materials and products can be treated with this kind of rust inhibitor in different stages, the industrial demand is huge, the market prospect is very considerable.

In addition, the research and development of multifunctional water-based rust prevention liquid and application become a trend gradually, such as oil, rust removal "2 in one", oil removal, rust prevention products are also increasing, such as the Cortec United States develop a series of products. Through emulsification of oil layer, infiltration and transformation of rust layer, it can protect metal products. Research and development of water-based metal rust inhibitor with excellent rust resistance, stable property, low price, reduced pollution, complete function and easy to apply.
