The drive towards safer industrial coating formulations triggered the development of a two-pronged approach to 2K resin systems for metal substrates. The non-isocyanate (NISO) approach provides sustainable advantages, and Arkema has made recent advances in lowering the coating VOC level while maintaining performance. Alternatively, development has also progressed in HAPS-free solvent systems. We will present case studies based on both of these proven robust solutions.
