Radiation Curing utilising Light Emitting Diodes (LED) offers substantial energy savings for industrial wood coating applications compared to conventional UV mercury arc lamps (~60% less) and traditional gas fired drying systems (~90% less). However, the growth of Radiation Curing applications has been limited due to: Poor depth penetration of UV in pigmented coatings; Poor surface coating properties (due to oxygen inhibition) and the absence of optimised coating formulations. NIRVANA will deliver 3 novel solutions to these challenges by:1. Developing an innovative near-infra red (NIR) photoinitiator within the 880-1000 nm transmission window where light is not typically absorbed or scattered.2. Developing novel hybrid organic-inorganic nano-materials to increase surface cross linking density and hardness and reduce oxygen inhibition.3. Creating formulations of 100% solids acrylate based resin wood coatings that can be cured using energy efficient NIR LED irradiation

与传统的紫外线汞弧灯（减少约 60%）和传统的燃气干燥系统（减少约 90%）相比，利用发光二极管 (LED) 的辐射固化可为工业木材涂料应用节省大量能源。然而，由于以下原因，辐射固化应用的增长受到限制： 紫外线在着色涂料中的深度渗透性较差；表面涂层性能差（由于氧抑制）且缺乏优化的涂层配方。 NIRVANA 将通过以下方式提供 3 种新颖的解决方案来应对这些挑战：1。在 880-1000 nm 传输窗口内开发一种创新的近红外 (NIR) 光引发剂，该窗口中的光通常不会被吸收或散射。2．开发新型有机-无机杂化纳米材料，提高表面交联密度和硬度，减少氧抑制。 3．创建 100% 固体丙烯酸酯树脂木器涂料配方，可使用高效节能的近红外 LED 照射进行固化
