Why do paint and ink manufacturers choose fluorescent brightener OB?
Why do paint and inkmanufacturers choose fluorescent brightener OB? There are mainly the following reasons：
Good solubility and dispersibility:
In terms of solubility, fluorescent brightener OB can be dissolved in many organic and can be well dissolved in the paint and ink system , without impurities and precipitation, ensuring the purity and whitening effect of paint and ink. Some other fluorescent brighteners may have poor solubility and cannot meet the use requirements of paint and ink.
In terms of dispersibility, after stirring, fluorescent brightener OB can be evenly dispersed in paint and ink, making the whitening effect more uniform and there will be no local over-whitening or insufficient whitening. This is very important for paint and ink products that pursue high quality and uniform appearance.
Excellent weather resistance:
In the use process of paint and ink, they will be affected by environmental factors such as light, temperature, and humidity. Fluorescent brightener OB has good weather resistance and is not easy to decompose or fade due to environmental factors, and can maintain the whiteness, brightness, and vividness of paint and ink for a long time. Especially for outdoor paints such as building exterior wall paint and road marking paint, and inks that are exposed to the air for a long time, such as outdoor advertising inks, the weather resistance advantage of fluorescent brightener OB is more obvious.
Significant optical whitening effect:
The whitening principle of optical brightener OB is optical whitening, It can absorb invisible ultraviolet light and convert it into blue light. The blue light and the yellow light of the paint and ink itself are complementary to each other to form white light and reflect out, thereby making the appearance of paint and ink whiter and brighter. Compared with traditional whitening methods (such as adding titanium dioxide), the whitening effect of fluorescent brightener OB is more significant, which can greatly improve the whiteness and brightness of paint and ink, and this whitening effect is more natural.
Little impact on the performance of paint and ink:
Fluorescent brightener OB has good compatibility with other components of paint and ink. After adding it, it will not have adverse effects on the performance of paint and ink, such as drying speed, adhesion, and hardness. This enables paint and ink manufacturers to not need to worry about affecting the overall performance of the product due to the addition of a brightener.
Convenient to use:
Fluorescent brightener OB usually exists in powder form. In the production process of paint and ink, it only needs to be stirred or ground evenly with other raw materials. The operation is simple and convenient and will not increase the complexity of the production process.
Wide application range:
Fluorescent brightener OB is not only suitable for whitening white paint and ink, but also can play a role in increasing vividness for colored paint and ink, making the color fuller and brighter. Therefore, it can meet the whitening needs of paint and ink manufacturers for different color products.
