Overview
Isophorone diisocyanate (IPDI) is a cyclic aliphatic diisocyanate synthesized via the dimerization of acetone followed by phoschation. Its molecular formula is C12H18N2O2 with CAS No. 4098-71-9.
Application
- High-performance polyurethane coatings for automotive finishes.
- Hydrolysis-resistant adhesives and sealants.
- Elastomers requiring superior UV stability and weathering resistance.
Precautions
Strict storage below 25°C in dry, ventilated areas is mandatory. Personnel must wear respiratory protection and chemical-resistant gloves due to severe sensitization risks.
