TREATMENTS, FINISHES AND SEALING

Types of treatments and coatings of metals

Finishes and treatments

High resistance blue passivation

Bi-chromate passivation (free from chromium VI)

High resistance iridescent passivation

HR treatment

Sealing

All finishes that we have are compatible with the subsequent sealing process .The sealing increases the protection of the passivation and zinc bath process.

Important note regarding sealing:
The sealing process consists of the deposition of a protective film on the passivation coating. This changes its original appearance, giving a more uniform finish in products subject to iridescent passivation and lowering the intensity of the original shine.
All this will always be based on the thickness of zinc of the piece. More thickness will endure corrosion better..
