Let's make it clear first, the yellow-green fluorescent powder we commonly see is not luminous. It will not glow in the dark by itself, and will only flash bright colors when sunlight or light shines on it. Once the light stops, it will "extinguish". So what does its "persistence" mean? Simply put, it is how long its bright color can last without getting dark or fading.
There will be some differences when using it in different places:
1. Indoor use (such as clothes, school bags, decorative paintings): If you use good quality fluorescent pigments, it can basically stay bright for 3 to 5 years or even longer, no problem at all.2. Outdoor use (such as billboards, skateboard stickers): Because the ultraviolet rays in the sun are quite strong, the fluorescent effect may gradually fade. Generally, it can last for a few months to 2 years.
How long can that can of fluorescent pigment last if it is not used?
If you have a can of fluorescent powder that has not been opened or has only been used a little, don't worry, it won't go bad so quickly. As long as it is placed correctly, it can be stored for 2 to 5 years without any problems! Pay attention to these small details: Don't put it in a place that is too hot or too humid: it will clump or deteriorate, like mold. Don't expose it to the sun: the sun will "age" it, and the color may change. Don't mix it with acidic or alkaline things: these will destroy its structure and the fluorescent effect will be gone.Continue to add more specific examples to give you a clearer understanding of the "maintenance time" of fluorescent pigments.
1. Fluorescent printing on clothing is mostly printed with fluorescent paint or fluorescent slurry. This type of printing is usually very bright and vivid visually, and is commonly used in sportswear, school uniforms, and fashion clothing. When worn indoors, the color can be kept for 1 to 3 years without obvious fading. If the clothes are often exposed to the sun, frequently machine washed, and exposed to detergents, the color may begin to darken or be discolored within 3 to 6 months. In order to extend the service life, it is recommended to wash on the reverse side, avoid strong sun exposure, use neutral laundry detergent, and avoid high temperature drying.
2. Fluorescent inks are widely used in book covers, posters, advertising printing, wrapping paper and other occasions. The colors are bright and attract attention. Generally speaking, the brightness of fluorescent inks on indoor prints can be maintained for 2 to 5 years. However, if used for outdoor billboards, due to long-term exposure to the sun and rain, the fluorescent effect may be significantly weakened within a few weeks to months. In order to extend the life of fluorescent ink: you can add anti-ultraviolet additives or use light-resistant fluorescent pigments, add coating or glazing treatment to prevent oxidation and photolysis
It can attract people's attention earlier and faster, keep this attention longer, and greatly increase the chances of people looking back for a second or even a third look. The earliest and most extensive commercial application of fluorescent pigments is various types of advertisements. From advertising signs inside and outside stores to huge advertisements beside highways; from various commodity packaging to various magazine covers and advertising inserts, etc. Commodity economy and scientific and technological development
Daylight fluorescent pigments are strictly speaking solid solutions of fluorescent dyes in brittle polymer resins. The latter is ground into fine powder to become pigments or colorants. The characteristics of its solid solution make it often transparent in application.
