Chemical surface preparation is an important anti-corrosion protection step, which affects the quality of the technological operations to be undertaken and the value of the final coating. According to what is required and what is attainable, the process may use solvent- or water-borne preparations.   Within a manufacturing process, chemical surface preparation may be inserted as a step into:

  • Inter-operational wash
  • Stripping of protective agents
  • Pre-coating wash
  • Operational or maintenance wash

The chemical surface preparation step includes:

  • Washing and degreasing (with/out phosphating)
  • Etching
  • Stripping of paint coatings
