Description

Acid Yellow 3 Aluminum Lake is a high-performance, insoluble pigment derived from the water-soluble dye Acid Yellow 3. This compound is valued for its excellent lightfastness, chemical stability, and vibrant yellow hue, making it a superior choice for applications requiring non-bleeding colorants. It is primarily utilized in industries where color consistency and durability are critical under demanding conditions. Key sectors include plastics, coatings, and specialty inks.

Application

• Plastics Coloring: For masterbatch, engineering plastics, and PVC, providing excellent dispersion and heat stability.
• Industrial Coatings: Used in automotive, coil, and powder coatings for durable, weather-resistant finishes.
• Printing Inks: Formulation of specialty inks for packaging and decorative applications requiring high opacity.
• Cosmetics & Personal Care: As a colorant in non-aqueous cosmetic products like lipsticks and eye shadows.
• Artists' Colors: Manufacturing of high-quality oil paints, acrylics, and other artist pigments.
• Textile Print Paste: For pigment printing on fabrics where a bright, wash-fast yellow is needed.
