Vactan - Rust Treatment / Rust Converter
VACTAN Rust Treatment / Rust Converter is a complex mixture of a vinyl acrylic copolymer and tannic acid
for the treatment of corroded steel and iron surfaces. VACTAN Rust
Treatment / Rust Converter 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 Rust Treatment / Rust Converter 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 Rust Treatment / Rust Converter can treat 8-9 square metres.

Application
- Surface Preparation:
-
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.
- Application:
-
VACTAN Rust Treatment / Rust Converter has been designed for application by spray and brush. By airless
spray a dry film thickness of up to 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 Rust Treatment / Rust Converter 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 Rust
Treatment / Rust Converter.
- Drying Conditions:
-
Temperature, humidity, 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 Rust Treatment / Rust Converter 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 risk of condensation or rain during this drying
period.
VACTAN Rust Treatment / Rust Converter can be used in the following areas: Manufacturing, Agriculture,
Automotive, Local Authority, Road Haulage, Chemical, Marine, Heavy
Engineering, Building and Construction, DIY, etc.
- Overcoating:
- VACTAN Rust Treatment / Rust Converter may be coated when cured with any conventional paint using
brush, roller or spray. Test pieces have been overcoated with one coat
of 2-pack polyurethane acrylic, applied by spraying.
VACTAN Rust Treatment / Rust Converter has been tested and certified as fit for use for the use for the
carriage of grain and use in potable water systems. It may also be used
in sensitive foodstuff areas.
- Health and Safety:
- VACTAN Rust Treatment / Rust Converter is non-flammable and can be regarded as essentially
non-hazardous under normal use. During use gloves should be worn as
VACTAN Rust Treatment / Rust Converter will stain the skin. Stains can be removed by first washing with
diluted bleach then plenty of soap and water.
VACTAN Rust Treatment / Rust Converter should NOT be swallowed. If swallowed wash out mouth with plenty
of water and then drink plenty of milk or water. SEEK MEDICAL ATTENTION
IMMEDIATELY.
KEEP OUT OF THE REACH OF CHILDREN.
VACTAN Rust Treatment / Rust Converter may cause slight eye irritation and should it come into contact
with eyes, washing with water is recommended.
SHOULD IRRITATION PERSIST SEE DOCTOR.
