General description

Isophorone diisocyanate (IPDI) is an aliphatic diisocyanate that is majorly used as a curing agent by forming −NCO linkages. It is mainly utilized in the preparation of various polyurethane products for a variety of high-performance coatings for automotive and industrial applications, medical devices, upholstery, insulation, and packaging applications, and in the manufacture of adhesives, sealants, and binders. It provides UV resistant films due to the presence of the aliphatic ring.

Application

IPDI is primarily used as a diisocyanate monomer in the production of polyurethane resins and elastomers. IPDI is highly reactive and can be used to produce polymer products with varying properties, ranging from rigid to flexible. Some of the primary uses of IPDI in polymer industries include:
  • Production of polyurethane coatings for automotive and industrial applications.
  • Synthesis of polyurethane elastomers used in medical devices and sports equipment.
  • Production of polyurethane foams used in upholstery, insulation, and packaging applications.
  • Use in the manufacture of adhesives, sealants, and binders.
  • In the synthesis of bridged silsesquioxane(BSQ) by sol-gel polycondensation with 3-aminopropyltriethoxysilane. The polymer of BSQ can be used to prepare the moisture-resistant film for UV filters.
  • As a healing agent in the preparation of polyurethane microcapsules by interfacial polymerization.
  • As a monomer in the synthesis of highly monodispersed polyurea microspheres via precipitation polymerization.
