Polythene Coated Anti-Corrosion Kraft
LDPE coated Kraft paper with corrosion inhibitor

The RUSTOP VCI System

BSK's Rustop materials prevent the corrosion of ferrous metals without the need for rust prevention coatings. When an item is enclosed, wrapped or interleaved with Rustop, vapours are emitted which saturate the air space. These vapours are adsorbed onto the metal surfaces forming a protective film. Any moisture present reacts with the film preventing corrosion. The film remains on the metal surface until the package is opened when it evaporates leaving a clean metal surface. The correct use of Rustop material ensures that the concentration of VCI vapours in the enclosed atmosphere is constantly topped up giving continuous protection. The system provides excellent vapour phase and contact inhibitor action.

Construction

• Pure MG kraft paper, printed on the MG side.
• Water-based corrosion inhibitor coating. Coated on the UG side.
• LDPE Coated on the Printed Surface

74.2 g/m2

Non Ferrous Materials

Rustop can be used in the presence of some non-ferrous metals. The following table indicates performance with some metals in common use.

Aluminium	Good protection
Tin & alloys	Good protection
Chromium & alloys	No adverse reaction
Silver & alloys	Tarnishing possible

Rustop is not recommended for Lead & solder, Copper & alloys, Magnesium, Cadmium and Zinc. Some cellulose paints and lacquers and synthetic materials may be discoloured, softened or embrittled in a saturated atmosphere. Tests should be undertaken on components containing unusual metal or alloys, prior to recommending the use of Rustop.

Hygiene & Safety

The Rustop formulation is safe for industrial packaging and can be used for indirect food contact applications. Good housekeeping and normal industrial hygiene practice should be encouraged including washing hands after using Rustop, especially before eating. It is preferable to work in a well-ventilated area.
