Color is the core component of the coating industry. Whether the acquisition of raw materials or the color control of coating production will have an impact on the consistency of the final color. Different from the traditional manual visual control, which controls the color by feeling and experience, the color control by spectrophotometer is a more reliable and convenient way.
The first is the upstream of the coating industry. The acquisition of raw materials requires color control, such as the resin of film-forming substances.

Resin particles this kind of granular resin, because the gap between particles will bring deviation to the test results, it is necessary to use a large-diameter colorimeter for color measurement.
Another example is pigments and fillers, such as toner. The color of powdered goods is the same as that of particles, and the control of color is also difficult. Even if the gap of toner is not as large as particles, the loose state can easily lead to different shades of color. In order to achieve better test results, it is recommended to press the powder into a cake with a powder former, and use a large-diameter spectrophotometer for color control.

Cs-820n is used for particle and powder measurement

Large diameter up to 30mm

If the color control of raw materials is difficult, the color control in the production of coatings will be more difficult. There are many factors affecting the color of coatings. The selection of different film-forming substances and resins will affect the color; Volume concentration (PVC), substrate and sample storage temperature affect the color; Curing temperature, different board making methods and other factors such as human factors will also affect the color of the coating.
Complex influencing factors add a lot of uncertainty to the control of color, and the use of spectrophotometer makes the whole process easier. Whether it is powder, particle, solid or liquid, the desktop spectrophotometer cs-820n can control the color.
