The project will be undertaken in collaboration with Beckers, a true pioneer in providing unique, high quality solutions that answer coating needs across many sectors.Research Focus:Currently, the majority of Coil Coatings are applied to continuous wide metal strip and then thermally treated so as to induce gelation or crosslinking. Currently this heating is carried out using gas powered ovens which yield a high carbon footprint to the finished article. As part of Beckers ongoing commitment to increasing the sustainability of Coil Coatings, new methods of crosslinking that have significantly lower carbon footprints are being explored. One such method is to use UV or Electron Beam radiation (radcure) to initiate free radical polymerisation. As these new technologies are being introduced into the Coil Coating market, there is a requirement to make sure that the performance of the new systems is at the same level as current systems.Project Aims:The specific focus of the doctorate will be to take a polyester melamine based, thermally cured standard system, and urethane acrylate based, radcure system; these systems will be applied to galvanised steel and the corrosion protection of the two systems will be evaluated. As part of the evaluation, accelerated testing will be compared to real world exposure data.Desired outcomes:Using a variety of analytical techniques including (but not limited to) SVET, SKP, EIS, Raman or IR spectroscopy, the aim will be to fully characterise the corrosion products of radcure systems and identify the mechanisms by which they are produced. This information can then be used to ensure that coating formulations used will support optimum corrosion protection.

该项目将与Beckers合作，Beckers是提供独特的高质量解决方案的真正先驱，可满足许多行业的涂料需求。研究重点：目前，大多数卷材涂料都是应用于连续的宽金属带材，然后进行热处理，以诱导凝胶或交联。目前，这种加热是使用燃气动力炉进行的，这会对成品产生高碳足迹。作为贝克持续致力于提高卷材涂料可持续性的一部分，正在探索具有显著降低碳足迹的新交联方法。一种这样的方法是使用UV或电子束辐射（radcure）来引发自由基聚合。随着这些新技术被引入到卷材涂料市场，有一个要求，以确保新系统的性能是在同一水平上作为当前的systems.Project目的：博士学位的具体重点将采取聚酯三聚氰胺为基础的，热固化的标准系统，和聚氨酯丙烯酸酯为基础的，radcure系统;这些系统将被应用到镀锌钢和两个系统的腐蚀保护将进行评估。作为评估的一部分，加速试验将与真实的世界暴露数据进行比较。预期结果：使用各种分析技术，包括（但不限于）SVET、SKP、EIS、拉曼或红外光谱，目的是充分分析辐射固化系统的腐蚀产物，并确定其产生机制。这些信息可用于确保所使用的涂料配方支持最佳的腐蚀保护。
