VCI Liquid


VCI liquid, a kind of unique water-based anti-corrosion liquid, may protect iron and nonferrous products and equipment from rusting even if they are placed in the liquid containing more than 400ppm of chloride. The product may prevent metal products from rusting in plain water, sea water, saline water and other strongly corrosive solutions containing sulfide and halogen for a long term. In addition, it is extensively applied to the marine as well as to the operation on plain water and sea requiring antirust at low cost. The product added to special microelements may be directly used for producing excellent, efficient and green VCI paper.


Features/Advantages
1.The VCI liquid can still play its antirust effects on work pieces soaked in corrosive water solution, chlorine solution and halogen solution.
2.The liquid can still fully meet the antirust demands even in the 100% relative humidity environment, .
3.The liquid is resistant to high temperature. Applying small amount of the liquid to the high-temperature deep-well equipment for petroleum or natural gas exploration can prevent the equipment from rusting.
4.The liquid may be applied to the short-term process antirust for machining parts, and may also achieve long-term antirust with their sealed packaging.
5.The liquid may be biologically decomposed, being unharmful to environment.
6.The liquid contains no chlorides, phosphate and heavy metals, being safe to environment. It passes SGS certification and meets RoHS directives.

Applicable Metals:
The VCI liquid is applicable to ferrous metal, alloy steel, cast iron, copper, brass, bronze, plated metal, zinc and its alloy, chrome and its alloy, cadmium and its alloy, nickel and its alloy, tin and its alloy, aluminum and its alloy, and other metal materials and their products.


Application Method:
1.Clean and dry the articles for antirust, without residual fragments, dirty marks and other filth left on them.
2.Evenly spray, brush or soak the articles for antirust with the primary liquid or its diluent, dry them in air, and keep them in a cool, dry place. For long-term antirust, place the treated articles for antirust in a plastic bag or other container for sealed package.
3.Spray appropriate amount of the liquid in a packaging unit (such as carton, packaging bag), and seal it immediately.
4.To achieve complete antirust without packaging, directly soak the articles for antirust completely in the liquid.
5.Operate with clean gloves, and do not contact the articles for antirust with naked hands.


Validity Period of Antirust:
Short-term antirust: two~three weeks (uncovered)
Long-term antirust: above two years (use according to required specifications)
Custody and Storage:
With sealed package, it shall be kept in a cool, dry place, away from sunshine and no contact with sources of ignition and corrosive materials. The quality guarantee period shall be twelve months from the date of delivery.
