The Birth of Ultra-Long Afterglow Luminescent Hot Melt Adhesive | Independent R&D Innovative Product by Hangzhou Junting Optoelectronic Technology

In the era of rapid development of smart transportation and safety infrastructure construction, night traffic safety, road landscape optimization, and hidden danger warning of public facilities have become core concerns of urban and rural infrastructure construction across the globe. Traditional road marking materials and safety warning products are highly dependent on external light sources, electric power supply and frequent manual maintenance, which brings high operation costs and potential safety hazards to long-term infrastructure operation.

To solve the industry pain points of short luminous duration, poor weather resistance, complicated construction and insufficient brightness of traditional luminous materials, Hangzhou Junting Luminescence Technology Co., Ltd. has independently developed a new generation of high-performance ultra-long afterglow luminescent thermoplastic after years of technical research, formula iteration and field engineering tests. This innovative product breaks through the performance bottlenecks of traditional luminous paints and ordinary marking materials realizing perfect integration of energy-saving luminescence, convenient construction, durable outdoor performance and multi-scenario adaptability, bringing a revolutionary new solution for global safety marking and road night lighting projects.

This ultra-long afterglow luminescent thermoplastic is a high-composite functional material developed based on the company’s core independent luminous pigment technology. We adopt self-developed long afterglow luminous pigments as the core functional raw materials, and scientifically blend and fully refine them with high-quality basic polymers, professional tackifiers, high-efficiency plasticizers, high-temperature and anti-aging antioxidants and other high-performance auxiliary materials through precise batching and constant-temperature mixing processes. The optimized formula structure not only retains the ultra-high luminous efficiency and long afterglow characteristics of the core luminous pigments, but also endows the product with excellent adhesion, flexibility, weather resistance and structural stability, effectively avoiding common problems of traditional luminous materials such as easy aging, peeling, fading and luminous attenuation after long-term outdoor use. All raw materials are screened in strict accordance with international environmental protection and engineering standards, with stable physical and chemical properties, no radiation, no pollution, safe and reliable for long-term use in public infrastructure and traffic scenarios.

The most prominent advantage of this product is its passive energy-saving ultra-long luminous performance. Different from electric luminous products that rely on power supply and traditional luminous materials with short afterglow time, our luminescent hot melt adhesive can automatically absorb natural light, sunlight and vehicle light radiation during the day or under bright light conditions. After sufficient light excitation it can realize stable and continuous spontaneous luminescence at night or in dark environments without any electric power, wiring or auxiliary energy supply equipment which greatly reduces the construction cost, power consumption cost and later maintenance cost of night lighting and safety warning projects.

With the international standard threshold brightness of 1mcd/m² as the measurement benchmark, the effective luminous duration of our product can reach more than 50 hours, which far exceeds the luminous duration of most similar products on the market, ensuring continuous safety warning and lighting effects for multiple consecutive dark environments such as rainy nights, foggy days and night power outages.

In terms of core luminous data, our product has achieved industry-leading ultra-high brightness and stable attenuation performance through professional formula optimization. The professional test data of the product’s luminous brightness (unit: mcd/m²) is as follows: the instantaneous luminous brightness reaches2600mcd/m² within 10 minutes after light excitation, showing ultra-high visibility in dark environment; the brightness remains 350mcd/m² after 60 minutes, maintaining excellent recognition effect; after 120 minutes of dark environment placement, the luminous brightness is still stable at 170mcd/m²; even after 180 minutes, it can still maintain a luminous brightness of 105mcd/m². The gentle and stable luminous attenuation curve avoids the problem of sharp brightness drop of traditional luminous materials, and ensures long-term uniform and effective luminous warning effect, fully meeting the high-standard safety identification requirements of European and Nordic roads, tunnels, public facilities and other engineering scenarios.

In addition to superior luminous performance, the product also has outstanding construction convenience and engineering compatibility. Unlike traditional luminous coatings that require multiple spraying, long drying time and complex process control, our long afterglow luminescent thermoplastic completely follows the construction process of ordinary thermoplastic marking materials. It can be directly constructed by using conventional road marking equipment without purchasing additional professional machinery and tools, realizing equipment sharing and process docking with traditional road marking projects. The one-time forming construction mode greatly shortens the construction cycle, reduces manual operation links, lowers the technical threshold of construction and overall engineering cost, and is suitable for large-scale batch construction and rapid emergency laying of safety marking projects.

Compared with the widely used traditional long afterglow luminous paint in the industry, our new luminescent thermoplastic has achieved comprehensive dimensional improvement in core performance and practical application. In terms of luminous effect, its luminous brightness is more than 3 times higher than that of traditional luminous paint, and the effective luminous duration is 5 times longer, realizing ultra-high brightness and ultra-long endurance luminescence. In terms of outdoor durability, the optimized polymer composite structure greatly enhances the product’s resistance to ultraviolet aging, rain erosion, high and low temperature cycle impact and road friction wear, effectively solving the problems of easy fading, powder falling and failure of traditional luminous paint after outdoor exposure. In terms of construction efficiency and applicability, the hot-melt integral forming process is simpler and more efficient, with stronger adhesion with the base surface, not easy to peel off, and longer service life, which can effectively reduce the frequency of later maintenance and replacement of engineering projects.

Benefiting from its excellent comprehensive performance, our ultra-long afterglow luminescent thermoplastic has a wide range of application scenarios, covering traffic roads, urban public facilities, rural infrastructure, industrial workshops and many other fields. In traffic road scenarios, it is suitable for road boundary lines, road isolation lines, zebra crossings, bicycle lane boundary lines and pedestrian walkway isolation lines, effectively guiding pedestrian and vehicle traffic at night and reducing traffic accidents. In urban and rural landscape and safety lighting scenarios it can be used for brightening paving of rural highway roads and park trails, realizing passive night lighting without power consumption. In high-risk early warning scenarios such as riverside roads and cliffside roads, it can be used as a high-visibility safety warning line to remind passers-by and vehicles of road hidden dangers in dark environments. At the same time, the product is also widely applicable to safety warning lines of workshop equipment and parking boundary lines of various transportation tools, providing all-round safety guarantee for industrial production and daily traffic operation.
