Uretdione and iminooxadiazinedione crosslinking chemistry: BASFRecent Research Landscape

Standard polyurethane synthesis suffers from high viscosity and limited thermal stability, which is mitigated through the engineering of iminooxadiazinedione and uretdione structural motifs. These specific chemical modifications allow for lower-viscosity processing and enhanced crosslinking density in high-performance coatings.

What technical problems is BASF addressing in Uretdione and iminooxadiazinedione crosslinking chemistry?

Poor aqueous dispersibility

(13)evidences

Standard isocyanate crosslinkers suffer from excessive viscosity and poor heat resistance during processing. Reducing these limitations improves handling and final coating durability.

Thermal yellowing and discoloration

(2)evidences

Polyisocyanate crosslinkers undergo chemical degradation during high-temperature curing or UV exposure that causes aesthetic and structural discoloration. Eliminating this instability ensures optical clarity and color fidelity in high-performance coatings.
