Invisible fluorescent

Introduction

Black light materials absorb UV/black light and then emit colorful fluorescence almost instantaneously. Light energy gets released very fast in the process. Thus, when the UV/black light is dimmed or blocked, the materials stop emitting fluorescence immediately.

Product Description
A. Color Conversion: From colorless from colored
Colorless (without UV)
Colored (with UV)

B. Color: Four colors available for organic dye. Five colors available for inorganic pigment.

a. Organic dye. Four colors

Blue-B BL-OB            Green BL-OG            Yellow BL-OYT             Red BL-ORT

Blue BL-BL            Green BL-CG           Yellow Green BL-YL           Purple BL-PP           Red BL-RD

Applications

A. Available Products & Applicability

B. Organic Black light Dye (powder)
a. Product Description
The average particle size of organic dye is 1-10µm, containing moisture ≦3%.
b. Properties
After dissolved in suitable solvents, the organic black light dye can be completely pervious to light, glowing well and low  concentration for use, suitable for ink/paint and plastic injection/extrusion.
c. Recommended Concentrations
For solvent based ink/paint 1%~10% w/w (2%)
(For best results, about 5% concentration is required for 20µm film thickness)
For aqueous based ink/paint 5%~30% w/w (15%)
(For best results, about 5% concentration is required for 20µm film thickness)
For plastic injection/extrusion 0.01%~0.05% w/w (0.02%)
(For best results, about 0.02% concentration is required for 0.2cm plastic thickness)
d. General Recommendations
Use clear resin as base material. Usage concentrations are directly related to process and print thickness.
When applied to ink, organic black light dye should be dissolved in suitable solvents first. Its solubility depends on the solvent formulations. Organic black light dye is suitable for screen printing offset printing gravure printing, flexo printing pad printing, coating and spray.
Applicable to PP- PE -PVC-PU-PS-ABS -TPR-EVA, Nylon and acrylics. Processing temperature should not be over 240℃.
It is recommended to use master batch for plastic injection/extrusion to be dispersed well. Master batch should be completely dry before use. When use black light powder for plastic injection/extrusion, well mixing black light powder with lubricants and additives if any before added to plastic for the best result.

C. Inorganic Black light Pigment (powder)
a. Product description
The average particle size of inorganic pigment is 1-10µm, containing moisture ≦3%.
b. Properties
Good light fastness, long durability, suitable for ink/paint and plastic injection/extrusion.
c. Recommended concentrations
For solvent/aqueous based ink/paint 10%~30% w/w(25%)
(For best results, about 25% concentration is required for 20µm film thickness)
For plastic injection/extrusion 0.1% ~5% w/w(0.2%)
(For best results, about 0.2% concentration is required for 0.2cm plastic thickness)
d. General recommendations
Inorganic black light pigment is insolvable in solvents. Applications of the product will be limited by its particle size. The product is suitable for screen printing gravure printing pad printing, coating, and spray, not applicable to offset printing and flexo printing.
Use clear resin as base material. Usage concentrations are directly related to process and print thickness.
Applicable to PP-PE-PVC-PU-PS-ABS-TPR-EVA, Nylon acrylics. Processing temperature should not be over 240℃.
It is recommended to use master batch for plastic injection/extrusion to be dispersed well. Master batch should be completely dry before use. When use black light powder for plastic injection/extrusion, well mixing black light powder with lubricants and additives if any before added to plastic for the best result.

4. Miscellaneous

A. The color of black light powder appearing upon exposure to ultraviolet (UV) radiation will be affected by other fluorescent materials, such as fluorescent dye and brightener. Avoid applying black light powder with these materials, neither the base materials containing fluorescent substances. Better use UV light to check all materials to see if there are any fluorescent substances contained before applications.

5. Others
A. Storage: Keep sealed in a dark, cool place, away from direct sunlight. Best within two years if stored correctly.
B. Safe for food grade packing and toys.
