Product Name: Light Chrome Yellow
Color Index Number: CAS [1344-37-2]; P.Y.34
Molecular Formula: 5PbCrO4·2PbSO4
Product properties: Insoluble in water, oil, and acetic acid; soluble in strong alkalis and inorganic strong acids. Turns black upon reaction with hydrogen sulfide and orange-red in alkaline conditions.
Main characteristics: Bright color, strong coloring power, good glossiness in paint production, can be formulated into light green with blue pigment.
Application Scope:
Coatings Can be used for traffic marking paint (yellow markings on roads and airport runways), metal anti-corrosion paint (as a coloring agent for primer or topcoat, commonly used for machinery, pipelines, and other process equipment), and ship coatings (paying attention to the impact of seawater environment on chemical stability).
Inks Used for coloring offset printing inks, solvent-based inks, and water-based inks.
Plastics Used for yellow color matching of plastic products such as PVC and polyethylene (PE).
Others Can be used for coloring ceramic glazes, architectural coatings, rubber products, etc.
Precautions: This product should not be mixed with acidic, alkaline, or reducing substances. Lightfastness: 1–8 grade (8 = best)；Weather Resistance: 1–5 grade (5 = best)；Acid/Alkali Resistance: 1–5 grade (5 = best).The stated values are based on our proprietary testing conditions. Customers must validate performance within their specific application systems.
