Phosphorescent luminescent pigment characteristics

Afterglow luminescent pigments can maintain visible 1-2 hours. But that depends on the type of excitation light source type and brightness , as well as luminescent pigments , outside light , dark adaptation of the eye , the coating area and visual distance and other factors.
* Excitation light in the ultraviolet content , Photoluminescent Masterbatch the excitation efficiency .
For example: a light source with the same illumination inspired brightness set to 100 units , then tungsten , white fluorescent light , compared with 180 units , and the black lights for 220 units.
* Luminescent pigment excitation time is basically not limited to stimulate the type and brightness of the light irradiation for about 2 --- 3 minutes to reach its saturation excited .
* Luminous pigment because of its brightness powdered paint pigments varies.
Initial luminescent brightness and afterglow luminescent pigment time is about 1.2-1.3 times the GB-U 's .
* Brightness phosphorescent pigment and its particle size increases with increased hiding power and dispersibility but its decline. Optimal particle size and dispersion of light emission efficiency and workability of 19 --- 25um.

Temperature change powder material uses

Coating: surface coating for all types of products, including PMMA paint , ABS paint , PVC paint , etc. ;
Ink: various types of printed materials , including fabric, paper , synthetic film, glass , etc. ;
Plastic products : Photoluminescent Masterbatch all types of plastic PP, PVC, ABS, silicone rubber and other materials of injection, extrusion molding .
Temperature change powder has a variety of low to high temperature range , depending on the temperature of different color can be divided into low temperature (10 ℃, 20 ℃), feel discoloration ( about 30 ℃) cheap gravel change color (40 ℃, 50 ℃, 60 ℃, 70 ℃, 80 ℃) and other materials ; temperature change pink colored to colorless , colorless to colored series.

Light emission intensity can be increased coating

The need for surface modification or coating materials processing , change surface properties of the pigment , improve the water resistance and weather resistance , and to improve the photoluminescent pigment dispersion in the coating , compatibility . Photoluminescent Masterbatch or aluminosilicate particles surface-coated nano waterproof layer ( titanium dioxide , zinc oxide , nano-alumina , nano- silica ), the luminous intensity of the luminous paint can be increased by 20 % or more, afterglow time extend more than 40% , water scrubbing more than 5000 times . Common luminous paint exists for the current poor impact resistance , abrasion resistance good , powdered paint pigments slower and other issues , the author uses environmentally friendly energy saving light-cured coating technology system, just a few seconds can be completely cured , add special plasticizer, may effectively address the issue.
