Studium Pasblu 10

• Trivalent blue passivation without cobalt
• Corrosion resistance of up to 48 h can be achieved (white corrosion on pendants)
• The obtained passivation coating can be glossy with a light blue color

Studium Pasblu 20

• Trivalent passivation blue with cobalt
• Corrosion resistance of up to 72 h can be achieved (white corrosion on pendants)
• Passivation produces a light blue color with red tint

Studium Pasblu 50

• Trivalent cobalt-free blue passivation with blue dye
• Corrosion resistance of up to 48 h can be achieved (white corrosion on pendants)
• Passivation produces an intense blue colour layer

Studium Pasblu 40

• Trivalent cobalt blue passivation
• Passivation has exceptional resistance to high temperature annealing
• Corrosion resistance over 72 h (white corrosion on pendants)

Studium Pastri 100

• Thick film silver passivation with a slight blue tint
• Passivation contains cobalt and is fluoride free
• The passivated coatings can be subjected to high temperatures without any loss of physical and chemical properties

Studium Pastri 300

• Thick film passivation slightly yellow to red
• Passivation contains cobalt and is fluoride free
• The passivated coatings can be annealed without negative effects on colour or corrosion resistance

Studium Pastri 400

• The most advanced thick layer passivation with an extremely intense blue color
• Passivation contains cobalt and other compounds increasing corrosion resistance, enough to meet the highest requirements
• The passivation coating can be annealed without any negative impact on the physicochemical properties

Studium Pastri 500

• Thick film passivation without cobalt with high corrosion resistance
• Passivation colour can be from yellow-red to green-blue
• The passivation solution is resistant to contamination

• Non-toxic zinc passivation with high corrosion resistance
• Based on chromium (III) compounds
• Lack of chromium (VI) is important for the waste water management and environmental protection
