VCI powder

◈ DESCRIPTION OF VCI POWDER

The VCI (volatile corrosion inhibitor) is a corrosion inhibitor for metal in ambient temperature.
VCI molecules from the product which is composed of the VCI that is available to be well evaporated in the air and has corrosion inhibition exclude water and oxygen that cause the corrosion.

The evaporated corrosion inhibition molecules from the powder can be sunk into a fine point and perfectly perform corrosion inhibition.
Especially, under the mood of the coexistence of moisture and oxygen, the effect of the corrosion inhibition continues from months to years and the processes for fat removal/washing are not necessary.
