Treatments before Coating

Any good coating starts with the individual pre-treatment of your parts. The adhesion of a subsequent coating is dependent on the quality of surface preparation thus the treatment has an immense importance for the production process.

In the treatment of metallic and non-metallic surfaces, In principle, there are three basic methods:

• layer-stripping processes such as sandblasting, sweeping, abrading, chemical degreasing or pickling
• layer-applying method as the galvanic deposition of metals and metal alloys
• layer-converting processes such as anodizing, passivation/chromating or phosphating.

In LZR a number of pre-treatments is offered. Depending on the requirements for corrosion protection, these are combined with each other to some extent.

A special form of treatment represents the tempering of galvanized steel.
