With gasification, VCI adheres to metal surfaces to form a compact protection film which plays a role of antirust. In the manufacture industry of pressure vessel such as boiler, VCI powder mixed with water is often used for hydrostatic test. Features/Advantages: 1 The VCI powder is especially applicable to the internal surface antirust of a confined space of the articles for antirust, including the articles cavity, hollow, curved faces, etc. 2 The continuous antirust effects remain if the confined space is enclosed after being opened. 3 After the articles for antirust are pun into the next procedure, the powder may be used without surface pretreatment. 4 No dirty marks will be left after the powder is applied, and it is easy to be removed by compressed air or cleaned by water. 5 The powder contains no silicones, phosphate and heavy metals, being safe to environment.
