Rust converters are intended to restore corroded metal surfaces. They are used at the initial stage of repair works.

What are the types of rust converters

By ingredients:

  • Acid-based. They are a mixture of acids and organic solvents. Unsuitable for galvanized surfaces and parts made of non-ferrous metal. They contain aggressive components and are relatively easy to use.
  • Zinc-based. These compounds contain zinc oxide as an active ingredient. They do not only eliminate already existing corrosion spots but also form a protective coating on the treated surface which prevents rust from spreading further.

By operating principle:

  • Modifying. Form a protective coating on the part that is ready to be painted.
  • Converting. Convert active corrosion products into barely soluble salts.
  • Stabilising. Convert unstable corrosion products into stable compounds.
  • Penetrating. Make the corroded area thicker.

Many products combine several mechanisms of action.

  6. The holding time of rust converters is also stated in the instruction. Some products are active within 10–15 minutes. Others take 24 hours for the reaction to finish.
  7. Converted products should be removed with a wire brush. The surface has to be washed and dried with a cloth.
