Functional pigments are a kind of pigments with special properties and application fields. Different kinds of functional pigments can not only give objects color, but also achieve more functions. These pigments include fluorescent pigments, luminous pigments, high-temperature resistant pigments, conductive pigments, etc., which play a unique role in various fields. This article will explore these functional pigments in depth, revealing their properties and wide range of applications.

Luminous pigment

Glow-in-the-dark pigments belong to rare earth energy storage luminescent materials, which have excellent light absorption, light storage and luminescence abilities. These pigments work by absorbing ultraviolet or visible light and storing the light energy in a lattice. In dark areas where light diminishes or disappears completely, glow-in-the-dark pigments are able to convert stored energy into light energy and glow, creating stunning effects. Glow-in-the-dark pigments can be used for marking, display, safety signs and other fields at night, providing a reliable light source.

Fluorescent pigment

Based on thermosetting resins, fluorescent pigments have excellent coloring power, fade resistance, extremely fine particle size and solvent resistance. When external light (including ultraviolet) shines on fluorescent pigments, they are able to absorb specific forms of energy, not converted into heat, but excited photons, in the form of visible light to release the absorbed energy, resulting in different colors of fluorescence. During the day, fluorescent pigments are more vivid and eye-catching than other pigments, and are widely used in signs, advertising, decoration and other fields.

Functional pigment types and application details

Conductive pigment

Conductive pigments usually use conductive carbon black as the main component, which has an antistatic effect and can prevent dust and charge accumulation on the surface of the coating. These pigments are suitable for applications where antistatic properties are required, such as electronic product assembly tables and computer room floors. In addition, metal powder pigments such as gold, silver, copper and antistatic agents also have similar antistatic functions.

Antirust pigment

Anti-rust pigment is a special kind of pigment, including red lead, zinc chrome yellow and so on. Zinc chromic yellow is one of the typical anti-rust pigments, in which chromic acid ions can form a layer of metal oxide hydrate on the surface of steel, play a passivation role, and effectively prevent rust and corrosion. Therefore, anti-rust pigments play an important role in protecting steel products. Among them, 109 zinc chromium yellow, 309 zinc chromium yellow and 509 zinc chromium yellow produced by Shanghai Chrome Yellow Pigment Factory have excellent properties.

High-temperature pigment

High temperature pigments are usually made of inorganic oxides and have excellent high temperature resistance, which can reach more than 800 degrees Celsius. These pigments have excellent weather resistance and are suitable for painting and marking in high temperature environments. Whether in aerospace, oil refining, high-temperature equipment painting or other high-temperature applications, high-temperature pigments play a key role.

Functional pigment types and application details

In summary, functional pigments offer new possibilities for applications in various fields. They not only give the material rich color, but also give it special functions, such as light, electricity, anti-static, rust and high temperature resistance. The continuous development and application of these pigments will further promote the innovation and development of coating, printing, logo, electronic products and other industries, and bring more convenience and beauty to our life and work.
