Detailed Specifications

Description Chem-Crest ProPass is an advanced, phosphate-free citric passivation concentrate specifically engineered as a deoxidizer and cleaner. Its primary functions are to eliminate surface impurities, bolster corrosion resistance, and clear away discoloration, tarnish, scales, and oxides. As a proven alternative to nitric acid passivation, it successfully passes critical evaluations like ASTM A967. For tailored application guidance, please contact a Crest representative.

Typical Contaminants Removed This formula is designed to remove light oils, greases, minor scales and oxides, and other general contaminants from part surfaces. To maximize the efficacy and lifespan of the passivating bath, it is highly recommended to perform an ultrasonic cleaning cycle before beginning the passivation process.

Operating Conditions

• Recommended Dilution:
  • Standard Passivation: 10–20% by volume.
  • Heavy Descaling: 25% by volume.
• Optimal Temperature Range: 150°–180°F (65°–82°C).
• Required Passivation Times:
  • 140°–160°F (60°–71°C): Minimum 4 minutes.
  • 120°–140°F (49°–60°C): Minimum 10 minutes.
  • 70°–120°F (21°–49°C): Minimum 20 minutes.
• Rinsing: For best results, use a rinsing water temperature between 100°–150°F (38°–65°C). Note: Contact your Crest representative for precise recommendations tailored to your specific product line and equipment.
