RUST ANODE is liquid zinc, which when applied to a
steel surface dries out in a 95% pure zinc coating. This coating bonds
itself to the steel, completely protecting it from corrosion. Even if
the zinc film is damaged or scratched it is impossible for rust to creep
between it and the surface it is protecting.
As a priming coat RUST ANODE gives permanent protection
providing that the finishing coat is intact. If the finishing coat is damaged
RUST ANODE will prevent corrosion by its sacrificial qualities - the period of
protection being dependant on the corrosive content of the atmosphere to
which the coating is exposed. The period can vary from 15 years in a
country district to 2 years in an industrial area.
RUST INHIBITION: The extraordinary rust inhibitive properties of RUST ANODE are shown by tests to be superior to more expensive measures of coating steel
SURFACE PREPARATION: The preparation of the surface
to be treated is reduced to a minimum since it is not required to be chemically
clean as with other treatments. It is only necessary to remove loose scale and
powdered rust with a wire brush and to ensure that the surface is free from
paint and grease. Sand, Shot or Grit Blasting Is the most effective where
possible.
HIDING POWER & SPREADING: The product has
excellent hiding power and coverage, which makes it economical to use. Only one
coat is necessary, except in severe conditions, when two coats would be
recommended.
SURFACE TOOTH: A RUST ANODE surface constitutes an
ideal base for the application of any further decorative finish if a colour
other than battleship grey is required. When further coatings are of a bitumen
base a high pigment content sealer should be used.
TEMPERATURES: The product will withstand temperatures
up to 204°C and has been shock tested between -4OºC and +204°C with no signs
of crazing, breaking up or loss of adhesion. Corrosion resistance remains
unimpaired.
TENSILE STRENGTH: The material has a high tensile
strength and always remains sufficiently ductile not to be affected by linear
expansion or even severe distortion.
BURNISHING: A pure bright metallic zinc finish can be
obtained very simply by brushing the surface when quite dry with steel wool. The result illustrates convincingly the practically pure zinc
composition of the dried film.
DRYING TIME: Touch dry within 30 minutes under normal
conditions,allow 24 hours before applying second coat or any other decorative finish. Sealer/Isolator coat
application after 8 hours.
NON-FLAMMABLE: The product is non-flammable when dry.
In the liquid state the flash points are sufficiently high enough to eliminate
fire hazards. 36°C.
TOXICITY: The material is entirely non-toxic (when
dry) and can be used with all safety for food containers, fresh water tanks
etc.
CONDUCTIVITY: The conductivity of the material when
dry is almost equal to that of pure zinc and for this reason it has found
extensive use as a Welding Primer.
