Tunnel-specific energy-storing luminescent multifunctional coating is made with ultra-long afterglow phosphorescent powder as the luminescent material. It is produced through a special processing technique by mixing the company's inorganic dry powder, various fillers, and additives in specific proportions. The ultra-long afterglow phosphorescent powder can emit light continuously for 12 hours. Energy-storing luminescent coating technology involves applying a flame-retardant, energy-storing luminescent coating on tunnel walls. This coating stores energy when exposed to any light source (including car headlights, electric lights, and even mobile phone light sources) and can emit light continuously for over 12 hours in the dark. It features enhanced brightness, delayed luminescence, scrub resistance, pollution resistance, and a long service life. Its light waves have the special ability to penetrate smoke during or after the emergency extinguishing of a light source, providing emergency illumination to ensure safe driving visibility and enhance safety. In the event of a tunnel fire, it can offer emergency escape lighting, reducing loss of life and property.
