Product Description

VCI powder, a kind of water soluble antirust powder that may be used in both dry process and wet process. It is mainly applied to corrosion-inhibiting treatment for internal surfaces of depression, hollow or cavity of metre articles. Fantastic antirust effect can be obtained by applying dry VCI powder in a confined space. 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.

Application Method:

1. Clean and dry the surfaces of the articles for antirust, without residual fragments, dirty marks and other filth left on them. 

2. When applying loose powder in a dry process, evenly spray the powder on the surfaces of the articles for antirust with a low-pressure air hose or a sprayer without particularly concentrating on any side and the articles may be sealed after the operation is completed.

3. When applying loose powder in a wet process, prepare the powder into 2% water solution, and then perform spraying, brushing, flushing or soaking procedures, and the articles may be sealed after the operation is completed.

4. When applying powder in bag in a dry process, place the powder bag within the distance (≤*0cm) where VCI is valid, and endeavor to place or suspend it in the upper space of the articles for antirust because the density of VCI antirust gas is larger than that of air.

5. Generally, the normal consumption is **0g***0g/m3, which will be increased under severe environment.

6. Operate with clean gloves, and do not contact the articles for antirust with naked hands.
