I. Product Performance:
1. After absorbing any visible light for 5-10 minutes, it continues to glow in the dark for over 12 hours and can be reused indefinitely;
2. Utilizes self-produced high-brightness luminous powder, which is safe, environmentally friendly, non-toxic, harmless, non-radioactive, and cost-effective;
3. Features double-layered tempered glass (ordinary ones only have the upper layer tempered, while the lower layer is regular glass). The light-storing interlayer uses high-brightness fully luminous aluminum plates, vacuum-sealed and laminated in a furnace, with waterproof and moisture-proof ratings up to IP68, and an aesthetically pleasing appearance.
4. The photoluminescent fire safety evacuation signs must meet the requirements of GA480.3-2004 for weather resistance, color adhesion, corrosion resistance, impact resistance, water resistance, and radioactivity.
