Rust conversion

The Tanex range of products is widely used in the formulation of acidic rust converter formulations. They can be used to formulate both resin-free pre-treatment solutions and acid-compatible water based film forming formulations.

By binding and converting poorly adhering iron oxides into more stable iron tannate complexes tannic acid based pre-treatments improve anti-corrosion resistance of new or old cast iron or iron work surfaces.

Boiler water treatment

The following tannic acid properties are of concern for water treatment purposes:

  • Oxygen scavenging
  • Preventing scale formation
  • Metal complexation

The Tanex range combines these 3 properties in one product, therefore allowing for simple formulated end products containing as few raw materials as possible.
