Job description

Dating back over 150 years, Beckers is a true pioneer in providing unique, high-quality solutions that answer coating needs across many sectors. Currently Beckers is proud to be the global leader in supply of coil coatings from 24 locations in 18 countries. Currently the majority of coil coatings are applied to continuous wide metal strip and then thermally treated so as to induce gelation or crosslinking. Work with Surrey has developed many aspects of the current understanding about how this occurs at the molecular scale (eg: , doi.org/10.1021/acs.analchem.7b04877, doi.org/10.1002/sia.1985). Currently this heating is carried out using gas-powered ovens which impart a high carbon footprint to the finished article. As part of the 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 understand how these radcure coatings adhere to each other, conventional coil coatings and metallic coil substrates (usually zinc-coated steel or aluminium). The specific focus of the project will be on the inter-coat adhesion between different coating systems by comparing dual-cure and fully radcure systems to standard thermally cured coil coating. X-ray photoelectron spectroscopy (XPS), time-of-flight secondary ion mass spectrometry (ToF-SIMS) and Auger electron spectroscopy (AES) will be used to characterise the interface of different cured coating systems and establish the mechanism of adhesion for the different regimes. Leading to an understanding of how the different chemistries used in both radcure and thermal curing affect the inter-coat interface, and consequently what effect this has on adhesion. This has the potential to bring about new formulations with improved performance. The project will benefit with the active involvement of Dr Gustavo Trindade from the National Centre of Excellence in Mass Spectrometry Imaging (NiCE-MSI) at NPL, to support our ToF-SIMS activities.About YouOpen to candidates who pay UK/home rate fees.
