Physical Vacuum Coating Technology
The V-Series utilizes vacuum metal-coating technology. Its material structure consists of an aluminum substrate, an adhesion layer, a 99.99% ultra-pure aluminum coating, and a protective and reflection-enhancing layer (composed of TiO2 + MgF2*). Unlike common protective and reflection-enhancing layers that rely on an SiO2 combination, the V-Series employs a TiO2 + MgF2 combination. Testing of this novel combination has demonstrated a 1.5% increase in total reflectivity compared to materials utilizing the SiO2 + TiO2 combination. In fact, its reflectivity can reach levels as high as 98%—a performance benchmark typically achievable only through the application of a 99.99% ultra-pure silver coating. This product not only significantly enhances reflective performance but also helps reduce material costs for customers.
The exceptional light-reflection performance of the V-Series products substantially boosts the light utilization efficiency of lighting, optical, and solar energy equipment. By enhancing product quality and extending product lifespan, it effectively contributes to energy conservation and reduced energy consumption, thereby satisfying customer demands for high-reflectivity aluminum materials.
*Introduction to MgF2
Magnesium fluoride (MgF2) is utilized in optical systems subject to highly demanding environmental conditions, exhibiting extremely high transmittance across the vacuum ultraviolet to infrared spectrum (110 nm to 6000 nm). Exposure to radiation does not induce the formation of color centers within the material. Furthermore, it possesses excellent mechanical properties, enabling it to withstand both thermal and mechanical shock; significant external force is required to induce cleavage in magnesium fluoride.
Application
1. V-Series
The V-Series comprises a line of ultra-high-reflectivity aluminum materials developed by Nosinda. These products boast a reflectivity exceeding 96%, with peak levels reaching as high as 98%. Key applications for the V-Series ultra-high-reflectivity products span diverse sectors, including optical lighting, electronics and appliances, automotive and aerospace industries, and medical equipment. Their exceptional light-reflection properties significantly enhance the light utilization efficiency of lighting, optical, and solar energy systems. Furthermore, they improve product quality and extend product lifespan, thereby effectively facilitating energy conservation, reducing power consumption, and meeting customer demands for high-reflectivity aluminum materials.
The V98 LED material—an ultra-high-reflectivity aluminum product developed by Nosinda—utilizes advanced vacuum metal surface coating technology. With a reflectivity exceeding 98%, this material is specifically engineered for the LED aluminum substrate industry, effectively boosting both the light output and thermal dissipation performance of the entire LED light source.
2. Superwhite
Superwhite is a highly diffuse reflective material with a reflectivity exceeding 96%, reaching as high as 98%. When utilized in LED lighting products, Superwhite’s UV-resistant and non-yellowing properties not only enhance the fixture's light output efficiency but also effectively eliminate dark spots and hot spots, thereby significantly improving the overall lighting quality. Available with either aluminum or steel substrates, the material supports various processing techniques, including roll forming, stamping, die-cutting, and punching.
