CHEMOPAS Passivations

Blue passivations (thin layer/ thick layer passivations) cobalt containing

CHEMOPAS 2003 HP

CHEMOPAS 2003 HP passivation is chrome-(VI)-free and contains a. o. trivalent chrome compounds and fluorides. Depending on make-up and operation conditions it can be used as high-performance blue passivation or as alternative product to chrome-(VI)-containing yellow chromations (referred to corrosion protection values).

Passivierung CHEMOPAS 2003 HP produces intensive even blue-purple protective layers on electroplated zinc surfaces with a considerably improved corrosion protection compared with conventional systems. Besides this the deposited layer has a very good colour stability at following tempering Steps (approx. 200° C) being used for driving out hydrogen.

CHEMOPAS Blau TOP

CHEMOPAS Blau TOP passivation is chrome-(VI)-free and contains a. o. trivalent chrome compounds and fluorides.

CHEMOPAS Blau TOP can be used as thick layer passivation as well as blue passivation (thin layer). CHEMOPAS Blau TOP produces intensive, even blue-purple protective layers on electroplated zinc surfaces with a considerably improved corrosion protection compared with conventional systems. Besides this the deposited layer has a very good colour stability at following tempering Steps (approx. 200° C) being used for driving out hydrogen.

CHEMOPAS AZUR

CHEMOPAS AZUR is a cobalt-containing high-performance based on trivalent chrome and fluorides. Depending on make-up and operation conditions it can be used as blue passivation or as thick layer passivation. Modern iron inhibitors render it possible to minimize the introduction of iron thus providing a exceptionally long service life. Besides that innovative additives are contained improving corrosion protection and temperature stability.

Black passivations

Chemopas Schwarz 2010

Chemopas Schwarz 2010 is based on trivalent chrome compounds and produces on alkaline plated zinc surfaces black conversion coatings showing in combination with a sealer a good corrosion protection.

For this post-treatment we recommend a sealer of our CHEMPALA series.

The benefits are:

  • the reachable corrosion protection is increased
  • a more even appearance with higher brightness can be obtained

Black coloration

CHEMOPAS 50 Schwarz (chrome-free)

CHEMOPAS 50 SCHWARZ can be used for black passivating electroplated zinc or zinc die cast surfaces. With CHEMOPAS 50 SCHWARZ deep black grip and scratch-resistant layers  can be obtained influencing neither the original gloss nor the dimensional accuracy. The colour layers are built up across different colour tones to the final deep black.

CHEMOPAS 50 SCHWARZ is delivered as salt and can easily be handled.

For this post-treatment we recommend a sealer of our CHEMPALA series.

The benefits are:

  • the reachable corrosion protection is increased
  • a more even appearance with higher brightness can be obtained
