Rust and corrosion are factors of major economic importance costing industry and consumers abnormal expenses. This unwanted expenditure can be curtailed/eliminated markedly through the use of petroleum-based temporary rust and corrosion preventives.

Various protective measures like alloying, plating, painting, etc. are used by the Engineering Industry to prevent metals from the effects of corrosion. While the measures indicated above are of a permanent/semi-permanent nature, petroleum based rust preventives find wide application for temporary corrosion protection during storage and transportation.

RUSTOP grades have been selectively formulated for various specific applications and offer the following advantages:

These are lubricating oils containing soluble corrosion inhibitors, and are generally applied by dipping, spraying or circulating. These serve as lubricants as well as temporary protectives. These products are suitable for internal protection of gear boxes, back axle assemblies, oil and fuel pumps and lines, fuel and oil tanks, I.C engines etc. Rustop S is the most suitable grade for protection of Cold Rolled Steel components. It has very good coverage and most suitable for application in humid and saline atmosphere.

These products are soft, waxy solids at room temperature. They do not contain any solvent, but their base materials are oil with additive like wax, lanolin and petroleum sulphonates. The rust preventive is melted for application. These types are suitable for highly finished as well as normal machined surfaces.

The materials can be applied to many types of assemblies by hot dipping. They are equally suitable for piston assemblies, oil seals, transmissions and timing chains, single items such as milling cutters, plain bearing inserts and highly finished gauges etc.

These products are mobile liquids consisting of film forming ingredients, rust inhibitors, and water displacing additives in solvent. On evaporation of the solvent, thin soft film is obtained.

RUSTOP 173 and RUSTOP 274 contain water-displacing additives, which means that all traces of moisture on the surface of components being coated are displaced by a protective film of these products.

RUSTOP 184 and RUSTOP 173 are used on a wide range of single items, also on interior surfaces where elaborate protection is unnecessary and in certain cases for the interim protection of assemblies. Because of the evaporation of the solvent, it should not be used where small-orificed cavities occur.

RUSTOP 274 is a premium rust preventive and is specially designed as protective for all types of bearings. Its superior characteristics protect the components for extended duration. It is also used as a sealant for phosphated components. It can be used for dual purpose—for inter process treatments as well as for application on the precision parts at the final packages stage. For final application the product can be used as such, whereas it can be diluted with Mineral Turpentine to cut costs when used for interprocess treatments. The product can be applied by spray or cold dip method.

This is a superior quality rust preventive blended with solvent refined base oil and special additives to provide extended protection periods. The product offers better water displacement characteristics and prevents the metal surfaces in severe salty and humid atmospheres.

It is recommended for use in all the applications for final packaging stage of finished components. It is, however, equally suitable for inter process waiting periods in the plant. The product can be applied by spray, swab or cold dip methods.
