With the widespread application of zinc oxide in coatings across various projects, its performance advantages have gained widespread recognition. To better utilize it, let’s explore how zinc oxide affects the color of chemical substances.

   The color of zinc oxide in coatings results from light reflection. White light is a composite spectrum formed by the proportional blending of various colored lights. If a substance appears pale yellow under natural white light, it indicates that the object absorbs some or all of the blue light spectrum. A substance's color stems from its selective absorption of light at different wavelengths. Light sources of different colors possess distinct wavelengths, and different substances absorb composite light of varying wavelengths. Substances selectively absorb this energy, equivalent to the total radiation emitted from the conversion of vibrational energy, rotational energy, and electronic kinetic energy within their molecular structures.

   Even within the same chemical substance, its hue varies depending on its electronic energy level. For instance, active zinc oxide—whether conventional or nanoscale—exhibits a yellow hue at high temperatures, which fades as temperature decreases. This occurs because the molecular structure and electron mobility of active zinc oxide differ at varying temperatures, leading to distinct absorption patterns of polychromatic light. For ceramic zinc oxide, adsorbed oxygen and methyl oxygen exist on its particle surfaces. The total amount of these two oxygen species fluctuates over time due to processes like water molecule adsorption, re-adsorption of atmospheric oxygen, and desorption of atmospheric oxygen. Consequently, the adsorption of various composite light colors by zinc oxide inevitably results in adsorbed oxygen and methyl oxygen being present on the particle surfaces.

   The above outlines the color properties of zinc oxide in coatings. Due to its high load-bearing capacity, long-term stable quality, wear resistance, weather resistance, and extended service life, proper operational methods must be strictly followed during use to avoid unnecessary complications.
