About Rust


Rust and corrosion are costing the world industry billions of dollars a year! In many countries, the majority of of industry is situated in a broad coastal strips, sea air is conducive to a high level of rusting taking place. In fact, rust has almost become part of our everyday life - with many industries virtually resigned to accepting rust as an inevitable and expensive cost.

Causes Of Rust

A number of low alloy steels and mild steels are iron in a state of non-equilibrium. Speaking scientifically, these materials tend to try and reach their lowest potential.

What this means in effect is that these materials try to return to their natural form - oxides and hydroxides of iron. Which we call rust. Because rust is a growth reaction, various elements are required for rusting to take place. For example, salt-laden sea air is highly conducive to creating a rusting action - and in fact, any moist air will assist rust to form.


Traditionally, covering materials (e.g. paints) have been used to protect iron and steel from the elements and airborne pollutants, which can cause rusting. However, the protection provided by covering materials is only as good as the preparation of the materials to be coated. Poor surface preparation is the prime cause of protective coating failure.

If any rust if left under the coating, it continues to grow - both into the metal and eventually through the coating. Usually, this insidious destroyer is not detected until major damage is done.

In more recent times, solvent-based rust converters have been tried. However, these also aren't very effective - because as soon as they contact the surface of the residual rust, they 'convert'. Which can still leave untreated rust underneath to continue its destructive work.

Liquid Engineering product EXIT RUST can dramatically cut this staggering wastage of materials and resources. Plant maintenance can be reduced. Rust contamination can be minimized. Equipment replacement costs can be significantly lowered. Another benefit for engineered structures is that rust can be effectively discounted, with the need for over-design being minimized.

For centuries it has been known that the bark of a number of trees (in particular, the mimosa) afforded a high level of rust protection for iron and steel artifacts. On investigation, scientists found that the secret of the bark's protection was an acidic substance - Tannic acid.

After years of exhaustive research with tannic acid in combination with other chemicals, the result is EXIT RUST.

Exit RustEXIT RUST is water-based and non-toxic. It works by converting rust to a stable black surface of Iron Tannate/Haematite (Fe2O3) and Magnetite (Fe3O4), which works through a chelation chemical reaction to form a strong matrix bonding to the original metal.

The water base of EXIT RUST is a vitally important part of the process. The water is the traveling agent for the tannin chemicals to penetrate the porous rust. (Unlike solvent bases or coatings which function only on the surface of the rust.)

The result is that EXIT RUST, through a process of amalgamation, converts rust to a stable, non-growing material, which is black in appearance. Metals treated with EXIT RUST can be left in the black state, or covered with conventional metal-protecting coating and paints at the option of the user.

Water-based rust converters have an excellent track record spanning almost a decade. They are now widely accepted as being the most effective way of curing rust.

Developed in Australia for world conditions, through the application of advanced technology, EXIT RUST is a sure cure for your rust problem.

Please note: EXIT RUST is a rust converter NOT a rust preventative. It will not act unless rust is common to areas needing treatment.
