Glass Colors Cobalt Aluminate Blue Spinel

 

 

FULLN CHEMICAL glass color Cobalt Blue FU-G584 C I PIGMETN BLUE 28 (77346) is a blue complex inorganic  color pigment for glass. 

 

Cobalt Aluminate Blue Spinel (PB 28) is a high-performance inorganic pigment known for its vivid color and exceptional stability. 

 

Key Features of Cobalt Aluminate Blue Spinel (PB 28)
Vivid & Clean Hue – Exhibits a bright, saturated cobalt blue, often with a subtle greenish or sky-blue undertone.
Excellent Chemical Stability – Its spinel structure provides strong resistance to acids, alkalis, and solvents.
Outstanding Heat Resistance – Withstands high temperatures (typically above 1000°C) without fading or decomposing.

Superior Lightfastness & Weathering Resistance – Highly stable under UV exposure and harsh outdoor conditions.

Eco-Friendly Profile – Free from lead and cadmium; complies with RoHS, EN 71-3, and other international safety standards.

 

 

 

 

Cobalt Aluminate Blue Spinel (PB 28) Advantages in Glass Ink Applications
Glass inks often require high-temperature firing and long-term durability. Cobalt Aluminate Blue Spinel (PB 28) offers the following benefits:

High-Temperature Stability – Maintains color integrity during the firing/sintering process of glass inks (typically above 550 °C).

Good Compatibility with Glass – Matches well with the thermal expansion of glass, ensuring strong adhesion and minimizing cracking or peeling.

Chemical & Environmental Durability – Resists fading from cleaners, acids, alkalis, and outdoor exposure, making it ideal for architectural, automotive, and appliance glass.

Long-Lasting Color Performance – Delivers intense, fade-resistant coloration that remains vibrant over time.

Process Versatility – Suitable for various glass printing techniques, including screen printing, digital printing, and roller coating.

FULLN CHEMICAL glass color Cobalt Aluminate Blue Spinel (PB 28) FU-GS584 is developed for glass surface decoration. Compared with conventional inorganic pigments, Cobalt Blue FU-GS584  fineness is much smaller. The particle size distribution range of D100≦5um. Our Glass Colors Cobalt Aluminate Blue Spinel products have good dispersibility and covering. The glass pigment materials should be used in conjunction with low temperature flux. The temperature range of cryogenic flux is 500℃~800℃. The low temperature flux fineness is less than 1250 mesh. The ratio of glass pigment to low temperature flux is (1-3)/(7-9).
