Industrial coatings: “Significant opportunities for new materials”

Where does R&D in raw materials for industrial currently focus?

Martin Rogers: The development of raw materials is increasingly influenced by sustainability considerations. In industrial coatings, the most prominent sustainability factors include reducing volatile organic compounds (VOCs) and materials of concern (MOC), minimising carbon footprint, and enhancing performance to extend the lifespan and durability of coatings. An example of research and development efforts to address remaining requirements is improvement of waterborne coatings through advancements in resins and additives. The need for innovation continues in replacing materials of concern with new materials of similarly high performance with significantly less impact on health and environment. One example is new resin development offering increased durability and weathering resistance without the use of heavily scrutinised materials. Other examples include formaldehyde and melamine-free systems. Current advancements in raw material development are moving to more sustainable materials in industrial coatings with low VOCs and MOC, greater durability and improved carbon footprint.

What eco-friendly or bio-based materials are currently gaining traction in the industrial coatings market?

Rogers: Bio-based materials have the potential to make a substantial impact on reducing carbon footprint and eliminating materials of concern. There is growing recognition of the value of rediscovering long-standing products as bio-based materials, particularly those derived from cellulose and plant oils like soy, cashew nut or castor. In industrial coatings, progress is being made in utilising recycled content to help reduce waste while minimising carbon footprint. There are also recent advancements in converting carbon dioxide into resins for use in coatings. Many of the new eco-friendly technologies or bio-based materials that could provide potential reduction in carbon footprint or waste are relatively early in development and adoption by the industry.

Looking ahead, what trends and challenges do you think will shape the sector in the near future?

Rogers: The industry will face ongoing challenges to innovate due to changing regulations. Potential regulations of perfluoroalkyl substances, reclassifications of exempt solvents and growing focus on microplastics will necessitate continued innovation in industrial coatings. Decarbonisation efforts across the economy present significant opportunities for new materials. The rise of electric vehicles and batteries, as well as the development of infrastructure associated with renewable energy, creates new coating demands and requirements. Across all of these challenges, digitalisation in material design and enhancing the ability to collect, store and analyse data will play a critical role. In response to these challenges and opportunities, the industry will need to continue to innovate, explore alternative materials and develop coatings that align with evolving regulations and market demand.
