UV Activated Dye – Ranbar Orange DP2050

Ranbar Orange DP2050 is a spirooxazine-type UV activated dye. This dye reacts to solar radiation as well as artificial ultraviolet light sources. When exposed to sunlight or ultraviolet (UV) radiation, the dye is excited, causing a change in its molecular structure, resulting in an orange color. Upon removal of sunlight or ultraviolet light, the dye returns to its quiescent state, i.e., colorless form.

UV activated dye molecules are not reactive in their crystalline state and require dissolution in solvents or polymers to be effective. It can dissolve in various organic solvents such as toluene, ethyl acetate, acetone, methanol, tetrahydrofuran, etc.

Ranbar UV activated dye can be mixed with other conventional dyes to achieve tinting effects, by mixing primary colors, colors can be matched to show colorless or light colors.

UV activated dye have a wide range of applications and can be used in various industries such as paints, inks, plastic products, and fabric dyeing. For example, they are used in doll hair, toy products, sunglasses, jelly shoes, hairpins, combs, shoelaces, coasters, craft items, watch straps, spoons, cups, Frisbees, greeting cards, stickers, business cards, UV detection equipment, anti-counterfeiting printing, safety badges, nail polish, T-shirts, and various clothing items, etc.

For oil-based inks and coatings 0.02%~0.3% w/w(0. 1%)

For plastic injection and extrusion 0.01%~0.3% w/w(0.01%)

1. UV activated dye need to be dissolved in a suitable medium (such as resin) to produce photochromic phenomena. The polarity of the medium has a great influence on the color changing performance of this product. It is recommended to make a sample to confirm the color development state before use.

2. UV activated dye are very sensitive to the influence of solvent, pH value and shear force. It is important to note that individual colors vary in performance, so each color should be thoroughly tested prior to commercial application.

3. The decomposition temperature of UV activated dye is relatively low. If there is a high-temperature process, it is recommended that the processing temperature not exceed 220 degrees and the processing time not exceed 30 minutes. Lowering the processing temperature or shortening the high-temperature processing time will help improve the discoloration performance of the final product. It is recommended that customers conduct a small test before use.

4. It is susceptible to the influence of light, oxygen, pH value and other factors in the environment. Lo ng-term exposure to ultraviolet rays will cause photoaging, which will reduce the discoloration ability of UV activated dye. The intuitive performance is that the service life is shortened or even the photochromic ability is lost. Please note that the container is sealed and stored in a dry place away from light.
