The photoluminescent pigment could also be used as additive for making of plastic molding materials Chemical property Composition: alkaline earth aluminates Insoluble in water, alkalis, organic solvents Decomposition by acidsLuminance properties Excitation wave length: 240-440nm Peak value: 520um glowing color: yellow-greenCompliances: DIN67510 Part 1 Warranty All sunfor photoluminescent pigments can be used repeatedly. The Y, B, P series have a lifespan of more than 15 years with good perfomance. Regarding the D series, we can gurantee 3 years as the color will die out gradually from the UV radioactivity. ADVANTAGE OF Photoluminescent Material 1. Self luminous in darkness after short absorption time in lights After absorbing invisible light (such as sunlight, lamplight etc.) for 5 to 10 minutes, the signs can glow for 15 consecutive hours. The light-absorbing and light-emitting process can cycle, signaling directions for people in the darkness. 2. High initial brightness and long afterglow duration The photoluminescent fire safety sign produced by Sunfor has been tested by the National Quality Supervision and Inspection Center of Fireproofing Construction Material. Initial Brightness can reach 30,000mcd/m², and 500mcd/m² after 10 minutes. 3. Energy Saving and Environmentally friendly It can produce light automatically without electric power. Inspections show that it has stable chemical performance and is free of toxins and radiation, which proves that it is a valuable Green high-tech product. 4. Easy Installation and Convenient Maintenance 5. Long Lifespan (last for 20 years plus) 6. Beautiful Appearance
