Standard polyisocyanate curing agents suffer from excessive viscosity and poor thermal resistance during processing. Reducing these limitations improves flow characteristics and durability in high-performance coatings.

Conventional polyurethane linkages suffer from low heat resistance and premature thermal decomposition. Replacing these with oxazolidinone structures addresses the inherent fragility of the polymer backbone under high-temperature conditions.

Polyisocyanate curing agents derived from cycloaliphatic diisocyanates suffer from chromatic degradation during processing or storage. Preventing this discoloration maintains the optical clarity and aesthetic integrity of high-performance coatings.
