AN ALTERNATIVE TO HOT DIP GALVANIZING

RUST-ANODE® is a cold galvanizing anti-corrosion treatment where zinc actively bonds to the steel’s surface.
RUST-ANODE® cold galvanizing lifespan is equivalent to hot dip galvanizing, with equal zinc weight and thickness.

BETTER THAN ANY OTHER ANTIRUST PAINT

RUST-ANODE® transforms (inhibits) the appearance of rust and prevents it from forming.
Rust is prevented from spreading and RUST-ANODE® bonds permanently.

IT IS NOT A PAINT

The only similarity RUST-ANODE® has with a normal paint is its application, by brush, roller or spraying. Everything else is absolutely different from other types of anti-corrosion paints such as
the composition and the technical protection.
Protection with the usual anti rust paint: they always decompose and crack in the end.

Protection with the usual anti rust paint : they always decompose and crack in the end. The rust spreads under the paint layer and finally the rust will lift the paint layer up and will cause
further rust forming.

RUST-ANODE®: COLD GALVANISING

RUST-ANODE® is a cold galvanisation and contains about 96% pure zinc dust in the dry layer. This zinc coating protects electro-chemically the steel surface. It offers the same cathodic protection as hot-dip galvanisation, metalisation or zinc coating by electrolysis. The RUST-ANODE® protection is far better than the one offered by any other traditional anti rust paint.

RUST-ANODE® acts as an active couple with the steel. It acts as a converter (inhibitor) of the rust and avoids its development. Rust doesn't extend and the adhesion of the coating remains total.

THREE PROTECTIONS AGAINST RUST IN ONE PRODUCT

  1. RUST-ANODE® provides a cathodic protection. If the coating is damaged then the generalprovides a cathodic protection. If the coating is damaged then the generalcathodic action from the coating around will provide the required protection (up to 4 mm scratch).
  2. RUST-ANODE® neutralises and transforms the eventual remaining rust as a rust inhibitor, so rust cannot extend any more its destroying action.
  3. RUST-ANODE® contains a resin or binder material, which appears partially at the surface and provides a supplementary surface protection. It will delay the zinc oxidation and extends the lifetime expectation of the cold galvanisation.

TRIPLE ECONOMY

  1. RUST-ANODE® is at the same time a full active cathodic protection and a passive paint protection.
  2. The lifetime expectation of RUST-ANODE® is the same of the one of hot-dip galvanisation (10 to 50 years). By applying a topcoat on top of the Rust-Anode one can increase the lifetime expectation by about 2,5 times!
  3. RUST-ANODE® can be applied on top of an older layer and any old hot-dip galvanisation and will renew itself. It has the property to reload the cathodic protection. The old and new layer of Rust-Anode or hot-dip galvanisation will meld together. Surface maintenance of old hotdip galvanised installations can be done without dismantling.

CAN BE APPLIED ON RUST

RUST-ANODE® acts also as a rust inhibitor (transformer). A thin layer of dust (fly-dust) is acceptable. The remaining rust will be transformed to iron hydroxide and will form the electric connection trough the layer providing the required cathodic protection.
RUST-ANODE® presents also the great advantage that it may be applied without any extensive chemical process such as pickling, passivation, phosphatation, etc. One only needs a mechanical cleaning: steel brushing or blasting. Of course all contamination e.g. oil, grease and dirt must be washed away.

TOTAL ADHESION

RUST-ANODE® has a perfect adhesion with the steel surface and compared to hot-dip galvanisation shows also a new advantage: the RUST-ANODE® layer follows the dilatation and deformations of the basic metal e.g. the temperature dilatation and eventual bending of the steel. RUST-ANODE® layer will neither crack nor come loose. RUST-ANODE® can also be top coated with compatible paints without any surface preparation, except for a clean wash with water.

HIGH CORROSION RESISTANCE

RUST-ANODE® has references from the Belgian Railroad Company dating from 1956 and has been sold ever since all over the world without problems.
RUST-ANODE®has resisted the lab salt spray test of 2.000 hours and the enforced aging tests during more than 1.300 hours without any damage.

ON HOT-DIP GALVANISATION OR METALLISATION

When hot dip galvanisation or metalisation starts to rust (the zinc layer is worn out) then the cathodic protection is not any longer active and only an extra cold galvanisation layer can help to restore the cathodic effect.
RUST-ANODE® is, as a matter of fact, the only product able to “melt” properly to the old galvanisation or metalisation. It can be applied directly onto the old galvanisation after cleaning the surface with a brush and washing it with a high-pressure water jet to remove all dirt and zinc salts. The RUST-ANODE® will “melt” together with the old layer and reload the cathodic protection. The installation or construction has not to be dismantled for a new dot dip galvanisation.
RUST-ANODE® will never come loose or peal off. New galvanised steel can be touched up by RUST-ANODE® consequently the cathodic protection is restored. The product can be applied directly without any surface preparation. Damage from drilling, cutting or welding can thus be repaired in accordance with the ASTM A 780.

SPECIAL CASES: VERY CORROSIVE ENVIRONMENT

RUST-ANODE PRIMER®is used in several applications in the industry where very aggressive elements of corrosion prevail e.g. cement factories, paper mills, breweries, refrigerating halls, etc.
RUST-ANODE PRIMER® is used with a real success to protect ships, on and offshore platform, marine constructions and all harbour facilities.
RUST-ANODE PRIMER® can be over coated to increase the corrosive resistance without any surface preparation.
RUST-ANODE ® is preferred to hot-dip galvanisation process for all steel constructions in light profiles or thin plates because the hot-dip bath will deform these light structures.

REFERENCE FOR THE MOST DEMANDING PEOPLE

Since 1954 RUST-ANODE® is known and used in more than 50 countries. Its high qualities have brought it at the leading place of all rust-prevention methods.
RUST-ANODE® is approved and recommended by the most important official laboratories in Europe. In Belgium, RUST-ANODE® has asserted itself in all industrial branches. Rust-Anode is approved by numerous public utility services and official bodies for various applications: electricity pylons, sewers, road signs, bridges, marine works, pipelines, harbour installations.
