Luminous paint is a new kind of functional coating, it comes from rare earth extraction strontium aluminate can absorb light energy and slowly release in the dark environment, continuous fluorescence effect. Because of the luminous paint contains photochemical reaction components, its adaptability to environmental conditions in a certain extent is restricted, which exist the certain difficulty for outdoor applications. From the point of weatherability, the service life of luminous paint will be affected by temperature, humidity and uv. High temperature, strong ultraviolet ray can accelerate coating aging, reduce product performance; The low temperature affects the glowing effect of phosphor powder; High humidity will promote coating hydrolysis and moldy phenomenon. Although some weather resistance of high performance products has been improved greatly, but compared with the ordinary paint, still slightly smaller. This limits the luminous paint under strong light and high temperature for a long time of use. However, luminous paint also have outdoor application advantages that nots allow to ignore. In the landscape design and architectural decoration, luminous paint can play a unique artistic effect. Luminous paint besmear to brush in building facades, landscape sketch, etc., in the night, the visual effect of magic. This provides a new approach to designers, favored by the landscape architect and architect. In addition, the safety instructions of luminous paint effect is also very suitable for outdoor applications. At the airport runway, highway warning labels on using luminescent paint, can effectively improve visibility in the night, extend the recognition distance, remind drivers and pedestrians pay attention to safety. It plays an important role in accident prevention night. All in all, luminous paint on the outdoor application has certain limitations, both also has vast potential space. Choose the right product, on the premise of long-term and strong light/heat, luminous paint can achieve the ideal decorative effect and the safety instructions. Especially in the city night view lighting, public facilities logo has great application potential. With the development of science and technology, luminous paint weatherability and performance continues to improve. Believe that through the product positioning and performance improvement, luminous paint will gradually reduced the difficulty of outdoor applications, thus play a role in a broader external environment, bring more fun night for cities and roads. It also will open new avenues for luminous paint industry.
