Our latest advancement in acrylic polyol emulsion transforms conventional 2K coating systems into safer waterborne non-isocyanate (NISO) solutions. This innovative product addresses market demand for safer and more sustainable alternatives, reducing carbon footprint without compromising on performance. 

Webinar & Key takeaways

Key takeaways

An evolution of Arkema 2-component coating resins towards safer and more environmentally friendly solutions:

  • Elimination of isocyanate sensitizer in paint formulation
  • Low VOC capability 
  • Less film aspect defect

Various formulation potential depending on crosslinker types (aromatic or aliphatic epoxy, epoxy silane): 

  • Direct-to-metal (DTM) 
  • Topcoat 

Arkema solutions to meet waterborne NISO market expectations


Waterborne non-isocyanate paint formulation using SYNAQUA® WB NISO can be completed with: 

  • Rheological additives: COAPURTM 790 (dispersing agent) and COADISTM XS 71 (thickener) 
  • UV stabilizer: SpeedBlock UV-92

This formulation example will provide:
