THE SUBSTRATE IS SOUND BUT SHOWING SIGNS OF RUST?

Using a rust converter 

 

High acid rust converters have been very popular in the treatment of rust but have shown only limited success in its prevention. Rustbuster fe-123 uses modern rust conversion technology contained in an eco-friendly compliant binder, containing zinc phosphate.

High acid rust converters leave residual acid in the steel's pores and this causes failure due to osmotic blistering. Often this cannot be removed by neutralising with fresh water and because of this introduces a new problem to the steelwork.

For true passivation to occur the reaction within the rust layers needs to be homogenous.

Due to its high molecular weight fe-123 can attract and incorporate several iron atoms. In addition, each single atom can be linked to three different molecules with FE123.

 

HOW TO USE FE-123 RUST CONVERTER

 

When you receive your bottle of FE-123 it will have settled out due to the zinc content in the binder just give it a good shake every time you want to use it this gets everything into a creamy consistency. Like all water-based coatings do not allow it to freeze.

Typically, Fe-123 can be applied to the ginger rust on the surface of steel. Or rust pitted steel that has been power tool cleaned. On application by brush the Fe-123 will start to react with the fe within the steels surface this reaction will produce a hard-black stabilised surface ready to paint. It does not need neutralising either.

 

Common problems that can stop the converter reacting

 

Two coats is not a good idea unless it’s obvious that you have missed a section. A second coat applied over a reacted coat will just turn a sort of toffee colour where the resin dries with nothing to react to. It will also go this colour if you apply it over a painted surface, any small rust spots on the surface of the paint should be spot primed by brush. There is no need to apply converter to a painted surface.

To enable the converter to work well do not degrease the area with a white spirit, diesel or paraffin as the oil in these products will prevent the Fe-123 from reacting.

Make sure to wash down and remove any grease from the surface prior to converting the rust as.

the grease will prevent the Fe-123 from reacting.

Make sure not to wire brush clean a dirty greasy surface as the wire brush will push grease and dirt into the rusty surface preventing the Fe-123 from reacting.

Use sparingly only enough Fe-123 is required to react with the surface of the steel. The Fe-123 is a surface treatment not a coating. A primer should be applied over the fe-123 as per you chosen paint system.

You can apply any of Rustbuster’s primers over an Fe-123 prepared surface.

We do not recommend Zinc rich coatings are applied over the FE-123 as the reaction and latex barrier have shut down the electrical connection with the steel that the zinc particles require.
