Vactan water based rust converter is a milky white latex coating that is applied to rusted metal to stop rust, protect the surface and act as a primer for the finish coat. Very little surface preparation is required before use. It is widely used in the commercial industry but can also be used in a domestic setting. It will treat rust on cars, car chassis, boat keels, engines… the list is endless…even your garden gate. If you have rust to treat then you need Vactan.

What is Vactan?

Vactan is a complex mixture of a vinyl acrylic copolymer and tannic acid for the treatment of corroded steel and iron surfaces.

Vactan neutralises the corrosion process by converting the rust into a blue black metallo-organic complex which passivates the surface. It then further protects the surface by forming a film with a low permeability to water vapour and oxygen.

Vactan is self priming but for long term protection it is advisable to overcoat with a suitable water or solvent base midcoat or topcoat. One litre of Vactan can treat 8-9 square metres.


Surfaces should be wire brushed to remove loose rust and it is preferable to remove soluble salts by washing with water as they inhibit the conversion process. Surfaces should also be oil and grease free. Vactan has been designed for application by spray and brush. By airless spray a dry film thickness of 60 microns can be achieved without sagging. The addition of further water may be necessary for air assisted spraying. By brush application, a dry film thickness of 40 microns per coat is considered optimum. Vactan can be applied over damp surfaces and dries quickly under suitable temperature and humidity conditions. Immediately after use equipment should be washed in water to remove all traces of Vactan.

Drying Conditions

Temperature, humidy, air movement and film thickness all affect the time to reach the touch dry stage. Under Ideal conditions a 100 micron wet film of Vactan will be touch dry in approximately 10 minutes at 20° C, whereas at 10° C and with little air movement this time can be as long as 2 hours.

Vactan should NOT be applied at temperatures below 10° C, or when there is a risk of condensation or rain during this drying period.

Vactan can be used in the following areas:

Manufacturing, Agriculture, Automotive, Local Authority, Road Haulage, Chemical, Marine, Heavy Engineering, Building and Construction, DIY, etc.


Vactan may be coated when cured with any conventional paint using brush, roller or spray.  The test piece shown here was overcoated with one coat of 2 pack polyurethane acrylic, applied by spraying.

Vactan has been tested and certified as fit for use for the carriage of grain and use in potable water systems.  It may also be used in sensitive foodstuff areas.

Vactan is non-flammable and can be regarded as essentially non-hazardous under normal use.


Vactan should be stored in a dry place. Do NOT allow Vactan to Freeze. Use Vactan within 12 months.

Health & Safety

Vactan is non flammable and can be regarded as non hazardous under normal use. During use, gloves should be worn as Vactan will stain the skin.  Stains can be removed by first washing with diluted bleach then plenty of soap and water.

Vactan should NOT be swallowed. If swallowed, wash out mouth with plenty of water. Seek medical advice immediately and keep out of the reach of children.

Vactan may cause slight eye irritation, wash out with water.  If irritation persists, seek medical advice.
