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 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 meters. This non hazardous product has been tested and certified as fit for use for the carriage of grain and use in potable water systems. Vactan should be used within 12 months of the purchase date, do not allow Vactan to freeze. Store in ambient conditions out of direct sunlight.
