Water based rust preventive liquids

An Eskimo's home is built of ice and yet it keeps him warm. Similarly, water although known to promote Corrosion in metals, especially iron and steel, can be an excellent solvent base for some of the environmentally safe chemicals such as prophylactic agents to control corrosion for short periods. The protection period is however sufficiently long to ensure in-plant and in-process protection. These products are ideal for protection from few hours to few days. Repitition of application however can extend the period of protection as desired.
This simple method of surface protection obviates the need for costly rust preventive oils and installation of conventional multi-tank system to clean the surface of oil, rust etc. on components by following cumbersome process. It eliminates totally the pollution caused by the cleaning system.
As there is no loss of liquid due to evaporation, usage of Suprabha VCI Water based Eco-friendly liquid for rust prevention will be economical.

Special Features

• 100% eco-friendly and environmentally safe.
• Neutralisation action removes acidic traces present in the surroundings and avoids any further attack on the metals.
• Protection against rust during manufacturing process.
• Eliminates the ill-effect of the reminiscence of coolant and fingerprints.
• Soluble in coolant hence eliminates the need for removing protective coating.
• Non-toxic, non-hazardous, non-inflammable formulation and mild odour makes it ideal for in-plant use.
• No need for wrapping and oiling during storage.
• Protected areas of the component do not require cleaning / degreasing thereby saves time and effort.
• Components when additionally wrapped in Suprabha Rustopaper can offer long periods of dry protection.
