WorléeAdd 458 is a nitrite-free flash rust inhibitor designed for use in water-borne coatings, particularly those based on latex. It serves to prevent the rapid onset of rust, commonly referred to as "flash rust," which can occur during the application of water-borne paints.

Key Features and Technical Data:

• Appearance: Colorless liquid.
• Non-volatile content: 38% ± 2 (measured after 1 hour at 125 °C, according to DIN EN ISO 3251).
• Density: 1.10 g/ml ± 0.02 at 20 °C (measured according to DIN EN ISO 2811-1).
• pH-value: 8 - 10 at 20 °C (delivery form, measured according to DIN ISO 976).

Application and Properties:

• Mechanism: WorléeAdd 458 works through an "anodic" action by precipitating an insoluble salt at the metal surface, forming a protective film that prevents rust discoloration during paint application.
• Usage: Suitable for use in emulsion paints and water-borne anti-corrosion paints, such as those based on W´Cryl 7158.
• Incorporation: It can be added at any stage during paint manufacture or as a post-additive.
• Effectiveness: Most effective at an alkaline or neutral pH.
• Dosage: Recommended dosage is between 0.2 - 2.0% of the total formulation. Optimal quantities should be determined through serial testing.

Storage and Handling:

• Ensure proper storage in a cool, dry place, away from direct sunlight.
• Follow the general standard terms and conditions outlined by Worlée-Chemie GmbH, especially concerning warranty and liability.

WorléeAdd 458 is particularly useful in industrial and architectural coatings where rapid rust formation needs to be controlled to maintain the integrity and appearance of the coating.
