Product Description:
Ranbar Blue I5060 cobalt blue pigment is a red light blue high-performance composite inorganic pigment based on cobalt oxide and alumina, indexed as pigment blue 28, with bright and brilliant color and strong coloring power, and its heat resistance stability can reach 1000℃ high temperature due to its high-temperature calcination in the production process.

Ranbar I5060 cobalt blue pigment has excellent chemical resistance, outdoor durability, and excellent coverage, is impermeable, migration resistant, and easy to disperse, and can be combined with high-performance organic pigments to form opaque shading pigments. cobalt blue pigment also has an infrared reflection function and can be used in roof insulation coatings, heat insulation films, and military anti-counterfeit coatings.

Product Applications:
The excellent performance of Ranbar I5060 cobalt blue pigment makes it widely used in applications requiring high heat resistance, weather resistance, and light resistance, mainly used in high-temperature resistant coatings, non-stick coatings, fluorocarbon coatings, exterior architectural coatings, automotive coatings, anti-counterfeit coatings, ceramics, enamel, glass coloring, and various high-temperature resistant engineering plastics coloring, and also as art pigments.
