2025-03-27
In the world of pigments, pigment yellow 191 has a unique performance. When it is in a light color state, it shows excellent heat resistance. This heat resistance is not ordinary degree, it can withstand up to 330 degrees high temperature. Imagine that in some high-temperature environments, such as those that are often exposed to the sun and the temperature is extremely high in industrial production scenes, or in some special high-temperature processing processes, many pigments may deteriorate due to high temperature, color change or lose the original performance. However, the pigment yellow 191 is safe, and with this heat resistance, it is particularly suitable for applications in high temperature environments.
At the same time, its light fastness is also good. In daily life, whether indoors or outdoors, light is everywhere. Long-term exposure to light will affect the color of many substances, just as some clothes will fade after prolonged exposure to the sun. However, the pigment yellow 191 can resist the light very well, it is like a loyal guardian, firmly maintaining the persistence of its own color, will not easily change color because of the influence of light.
In terms of coloring power, it is relatively low. However, this feature does not limit its use, but makes it play an irreplaceable role in some specific areas. Especially in the color matching work of light varieties, it is like a delicate artist, and can provide more delicate and soft color effects. This soft color effect is not the kind of strong and dazzling color, but gives people a light and comfortable visual feeling, like the first ray of sunlight sprinkled on the pale yellow flowers in the morning, the kind of light and soft beauty.
Applications:
• In the field of transportation, the pigment yellow 191 has a wide range of applications. It is mainly used in traffic coatings, such as road marking and traffic signs. Road markings are critical to traffic safety, as they need to be visible in a variety of complex environmental conditions and maintain long-lasting color vividness. The same is true of traffic signs, whether it is the glare of the day or the reflection of the light at night, it should be able to allow drivers and pedestrians to clearly identify. With its outstanding performance, pigment Yellow 191 provides eye-catching, long-lasting color effects. Yellow itself is a very eye-catching color, which can quickly attract people's attention on the road, and the light fastness and high temperature stability of the pigment yellow 191 ensure that this eye-catching color can last for a long time, providing a strong guarantee for traffic safety.
In addition to the transportation sector, it is also suitable for other applications requiring high temperature stability and light fastness. For example, some large outdoor equipment, these equipment long-term exposure to the outdoors, under the sun exposure, wind and rain erosion and temperature changes. The light fastness and high temperature stability of the pigment yellow 191 can keep the appearance color of the equipment good, and will not become patchy due to the influence of the external environment. For example, in some special building materials, it is necessary to maintain the stability of the color for a long time, and the pigment yellow 191 can also well meet such needs.
