As partially bio-based hydrophilic aliphatic polyisocyanate hardener based on bio-based pentamethylene diisocyanate (PDI), containing 61%* bio-based carbon, enabling partially bio-based 2K waterborne wood coating for furniture & parquet. Compared with HDI derivatives, it creates more value via reducing the cradle-to-gate carbon footprint significantly, and meanwhile improving chemical resistance as well as easy-to-use thanks to its high compatibility and easy mixing in water phase, nearly drop-in, & excellent chemical resistance.

* sourcing from non-fossil-based raw material (no direct conflict with food chain), 61±3% bio-based carbon in supply form, & the bio-based content is determined by measuring ¹⁴C according to ASTM D6866-21
