Phosphorescent Powder FAQ
Q: How long does Phosphorescent Powder glow after being charged?
A: Our premium Phosphorescent Powder provides visible glow for 8-12 hours after full charging, with the brightest glow occurring in the first 2 hours. The duration varies slightly depending on color choice - green typically lasts longest, while violet has shorter duration but more vibrant initial glow.
Q: What's the best way to charge Phosphorescent Powder for maximum brightness?
A: For optimal performance, expose the Phosphorescent Powder to direct sunlight for 30-60 minutes. Artificial light sources like UV lamps (365nm or 395nm) work well too, requiring about 2-3 hours for full charge. The powder reaches maximum brightness when charged under light sources with wavelengths between 250-450nm.
Q: Is Phosphorescent Powder safe for use in children's products?
A: Yes, our Phosphorescent Powder meets international safety standards including EN71-3 (Europe) and ASTM F963 (USA) for toy safety. It's completely non-toxic, free from radioactive materials, and contains no harmful heavy metals. The powder is chemically stable and won't leach chemicals during normal use.

| Green | 450 | 180 | 35 |
| Blue | 380 | 150 | 25 |
| Yellow | 320 | 130 | 20 |
| Red | 280 | 100 | 15 |
| Violet | 250 | 80 | 10 |
Mixing Guidelines
For best results when mixing Phosphorescent Powder with binders:
- Recommended concentration: 15-30% by weight
- Mix thoroughly to ensure even distribution
- Use transparent or light-colored binders for maximum glow
- For paints, add 1-2% clear dispersant to prevent settling
More Phosphorescent Powder FAQ
Q: What's the shelf life of Phosphorescent Powder?
A: When stored properly in sealed containers away from moisture and direct sunlight, our Phosphorescent Powder maintains its performance for at least 5 years. The photoluminescent properties won't degrade over time unless exposed to extreme conditions.
Q: Can Phosphorescent Powder withstand outdoor conditions?
A: Our specially formulated Phosphorescent Powder features excellent weather resistance. It's UV-stable and can withstand temperature fluctuations from -30°C to 80°C (-22°F to 176°F). For permanent outdoor applications, we recommend adding a protective clear coat.
Q: How does Phosphorescent Powder differ from fluorescent materials?
A: Unlike fluorescent materials that only glow under UV light, our Phosphorescent Powder stores light energy and continues glowing in darkness after the light source is removed. It provides longer-lasting, energy-efficient illumination without requiring constant UV exposure.
