Refers to the ability of pigments to withstand various climates. These include visible and ultraviolet light, moisture, temperature, atmospheric chlorination, and chemicals encountered during product use. The most important weatherability, including color fastness, chalk resistance and durability of physical properties. Organic pigments are good or bad because of their different structures. In addition, in formulations containing white pigments, the weatherability of the pigments is severely affected. The fading, darkening, or hue change of a pigment is generally caused by the pigment's reactive genes. These reactive genes can interact with moisture or chemicals in the atmosphere—acids and alkalis. For example, cadmium yellow will fade under the action of moisture and sunlight, and Lisol red has good light fastness and is suitable for most indoor applications, but it will fade seriously when it is used outdoors with acid and alkali components.
