UV fluorescent security pigments Characteristics
A organic phosphors
1. Fluorescence bright color, does not have a hiding power, light penetration rate of 90%.
2.Good solubility, all kinds of oily solvent can be dissolved. Due to different solvency, please choose according to different needs of use.
3. Belongs to dye series, should pay attention to color shift problems.
4. due to poor weather resistance, when you need to add other stabilizers.
5. Heat resistance: maximum temperature of 200 ℃, fit within 200 ℃ high temperature processing.
B inorganic phosphors
1. Fluorescence bright color, good hiding power (opacity can be added free agent).
2. Fine spherical particles, easily dispersed, 98% of the diameter of about 1-10μm.
3.Good heat resistance: maximum temperature of 600, suitable for high-temperature processing of various processes.
4. Good solvent resistance, acid, alkali, high stability.
5. There is no color shift, will not pollution.
6. The non-toxic, it does not overflow when heated formalin, toys and food containers can be used for coloring.
7. Color body does not overflow, when in the injection machine for mold, you can save cleaning procedures.
UV fluorescent security pigments Usage
UV fluorescent security pigments Can be directly added to the ink, paint, forming security fluorescent effect, suggested ratio of 1% to 10%, can be directly added to plastic materials for injection extrusion, suggested ratio of 0.1% to 3%.
1 can be used in a variety of plastics such as PE, PS, PP, ABS, acrylic, urea, melamine, polyester The fluorescent colored resin.
2. Ink: for a good solvent resistance and no color shift of the printing of the finished product does not pollute.
3. Paint: resistance to optical activity three times stronger than other brands, durable bright fluorescence can be used on advertising and Security Full warning printing.
