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:
