Corrosion worldwide and the battle for control
All ferrous metals corrode unless protected. The process is a complex chemical action that always involves the availability of moisture and oxygen. This persistent, destructive and degenerative process is accelerated by associated surface contaminants such as mineral salts and acids.

Only by absorbing or neutralizing surface pollutants and completely excluding moisture and oxygen from the metal surface can an adequate long-term protective system be achieved.

Existing rust control processes are only partially successful because they do not cope adequately with all three basic causes of ferrous metal corrosion: the elimination of surface contaminants, the removal of free moisture and oxygen from the metal surface and the protection of the treated surface by an impenetrable membrane.

NEUTRA RUSTŪ 661 The Revolutionary Complete Rust Control System
NEUTRA RUSTŪ 661 is a unique corrosion control system (Worldwide patents applied for) developed by NEUTRA RUST INTERNATIONAL LTD for use on rusted ferrous metal surfaces.

The ferrous surface to be protected is converted on contact to a black, complex organic iron compound by the unique deoxygenating agent incorporated in the NEUTRA RUSTŪ 661 converter.

This corrosion-resistant layer is formed by utilizing all the surface moisture and oxygen during the reduction reaction. Concurrently, the special copolymer latex, with 39% solids, dries to form an impermeable barrier to oxygen and moisture.

EXTREMELY LOW PERMEABILITY FACTOR: 20-25g/m²/25mm/day

The above photographs show the various colour changes and chemical reactions that occur during and after application of NEUTRA RUSTŪ 661 to a rusted surface.
