Talk about the application range of cobalt blue

Do you know what the use of cobalt blue is today we will understand!

Cobalt blue is a common inorganic pigment with a vivid blue tone and is widely used in a variety of fields. Its main component is cobalt oxide, which has good hiding power and coloring power.

First, let's look at the application of cobalt blue in industry. It has excellent high temperature resistance, so it is often used as high temperature resistant coatings, such as coil steel coatings, long-term coatings and so on. In addition, cobalt blue is also used for high temperature resistant engineering plastics coloring, such as fluorine plastics, plastic toys and so on. In ceramics, enamel, glass and other materials, cobalt blue can also show excellent coloring effect, not only beautiful and durable.

It is worth mentioning that cobalt Blue meets a number of international safety standards, such as the European Union ROHS standard, the European Union EN71-3 standard, the American ASTM F963 standard and the Japanese SONY standard. This means that cobalt blue can be safely used in plastic tinted products that come into contact with food.

In the field of art, cobalt blue has also played a role. It is a bright, clear blue pigment that is suitable for various artistic creations, including frescoes. Although the main color of cobalt blue is similar to ultramarine blue, its base tone is more purple, providing artists with more space for color expression.

In addition to the above uses, cobalt blue also has infrared reflection, which makes it useful in fields such as military anti-counterfeiting coatings and roof insulation coatings. These uses of cobalt blue benefit from its unique physical and chemical properties, such as high thermal stability, high chemical stability, excellent weather resistance, good dispersion, resistance to various solvents and chemical corrosion.
