Passivations and Chromates

Blue passivations

BLUPASS B

• Trivalent blue passivation without cobalt
• It is possible to obtain corrosion resistance up to 48h, to white corrosion on pendants
• The passivation layer can be glossy and light blue

BLUPASS BC

• Trivalent blue passivation with cobalt
• It is possible to obtain corrosion resistance up to 72h, to white corrosion on pendants
• The passivation gives a light blue color with a red tone

BLUPASS FB

• Trivalent blue passivation without cobalt with an blue pigment
• It is possible to obtain corrosion resistance up to 48h, to white corrosion on pendants
• The passivation gives a highly intesive blue color

BLUPASS HT

• Trivalent blu passivation with cobalt
• Characterized by a good resistance to heating in high temperatures
• It is possible to obtain corrosion resistance for more than 72h, to white corrosion on pendants

TRIBLU FTA

• Trivalent blue passivation with a low work concentration
• It is possible to obtain corrosion resistance up to 172h, to white corrosion on pendants
• The obtained layer is very blue with a slight red shade

Thick-layered passivations

TRISTAR FH

• Thick-layered passivation colored silver with a light blue tone
• It contains cobalt and no fluorides
• Passivated surfaces can be treated with high temperature with no loss of physical and chemical properties

TRISTAR FHT

• Thick-layered passivation with a light yellow to red tone
• It contains cobalt and no fluorides
• Passivated surfaces can be treated with high temperature with no negative affect on the color and corrosion resistance

TRISTAR FA

• The most advanced thick-layered passivation with a highly intensive blue color
• It contains cobalt and different compounds that are increasing corrosion resistance
• Passivated surfaces can be treated with high temperature with no negative affect on physical and chemical properties

TRISTAR FREECO

• Thick-layered passivation without cobalt with high corrosion resistance
• The color of the passivation can be from yellow-red to green-blue
• The solution of the passivation is resistant to pollution

Yellow passivations

YELLPASS

• Yellow chrome coating based on chrome VI
• Characterized by a good adhesion of the chrome layer what provides a good corrosion protection
• The color of the layer is from yellow to gold-green

YELLPASS M

• Yellow chrome coating based on chrome VI
• The process is working right even at low concentration
• The color of the layer is from yellow to green

YELLPASS EKO

• Non-toxic zinc passivation with a high corrosion resistance
• Based on chrome (III) compounds
• The lack of chrome (IV) is very important for the sewage and environmental protection

Black passivations

MA PASS 030

• Black trivalent passivation for kinds of zinc elektrolytes
• The layers are characterized by black color and gloss
• The passivation offers a corrosion protection at 24h on pendants and it has to be sealed/coated

Passivations for silver

ESPASS

• Chemical passivation process for parts made of silver and coated with silver
• The passivation layer does not reduce the conductivity or solderability of silver
• The layer is transparent and does not change the color of silver

Passivation tools

TRISTAR NANO

• Nanostructured strengthening for passivation
• It raises corrosion resistance
• It extremely raises the attrition of the layers

FENDEX

• This additive highly affects the lifetime of the passivation
• It restrains the dissolution of metals in the passivation
• It minimizes the negative affect of introduced pollutions
