European Coatings Show Preview December 2014 www european coatings show com 14 been made that have helped to lower costs improve effi ciency reduce VOCs and the carbon footprint and improve coating performance One of these is the compact coating process in which a primer or a second basecoat basecoat and clearcoat are applied wet on wet on wet and cured with a single bake This process eliminates the need for the primer sur facer and primer oven which helps the OEM to save en ergy costs and reduces VOC emissions and the carbon footprint of the whole manu facturing process Other examples are fit for use and lower cost solu tions These imply the devel opment of products with the right balance of performance and cost in use There is also a growing trend towards developing waterborne so lutions with solventborne performance as well as 1K solutions that offer 2K per formance xz Focus Accelerated adoption of green coating solutions Coating suppliers can help car makers to become greener Meeting regulations reduc ing VOC and the carbon foot print Eric Zhuang Allnex points out in which aspects suppliers of automotive coatings still have potential to improve  What are currently the most pressing problems that need to be resolved through R D into automotive coatings Eric Zhuang The most criti cal R D topics are address ing the key challenges of the automotive industry today and include VOC and carbon footprint reduction process efficiency and rationalisa tion and weight reduction Resin suppliers are focusing on developing creative and higher performance resin chemistries and formulation solutions to address these challenges Some examples of these are resins for coat ing processes resins for low bake CED primer surfacer and clearcoat technologies and primerless waterborne which have been adopted by several automakers in recent years and have helped to rationalise the OEM coat ing process save process and energy costs reduce VOC emissions and lead to sustainable growth Lower ing the baking temperatures of CED primer surfacer and clearcoat leads to lower en ergy costs and hence a more sustainable coating process Introducing high solids coating and powder coating technology into OEM and in terior coating as alternative technologies is another way to lower VOCs Baking steps between the coating layers will be increasingly com bined and this consolidation will principally take place between all four layers The automotive industry is a major driving force be hind the banning of certain solvents such as NMP and NEP from automotive coat ings This trend is starting in Europe and will certainly move to other global regions as well  What development in the automotive coatings field has been the most important in the last ten years Zhuang In the past ten years several critical innova tions and developments in automotive coatings have and more sustainable A key driver here is an increased awareness of and the need for compliance with more stringent regulations These subsequently create more challenges for coating sup pliers and accelerate the adoption of green coating solutions Sustainable and low VOC coatings could for example be achieved throught he use of water borne primer surfacers and basecoats for auto OEM and refinish The use of these continues to grow globally and has already brought significant benefits for the environment car makers the repair industry and individu als working in the trade Fur thermore low VOC coatings could be achived by compact coating processes including 3Wet High Solids 3Wet IPP Eric Zhuang Allnex resins for coatings on chal lenging substrates and final ly resins compliant with new regulations and REACH  What can the automotive coatings industry do to pro duce sustainable and low VOC coatings Zhuang As the automotive industry becomes more globalised car makers are striving to become greener Surface Competence Resins fi llers additives plus outstandig services for the European coatings industry Meet our experts Hall 1 Booth 1 420 France www lehvoss fr Italia www lehvoss it United Kingdom www lehvoss co uk Beijing www lehvoss cn Tel 49 0 40 44 197 0 Fax 49 0 40 44 197 351 E Mail info lehvoss de www lehvoss de Source Paul Brennan Shutterstock
