Isophorone diisocyanate, IPDI

Cas No.: 4098-71-9
MF: C12H18N2O2
Properties & Applications & PackagesInquiry
Isophorone diisocyanate (IPDI) is a clear to pale-yellow liquid with a camphorlike odor which is insoluble in water and miscible with most common organic solvents.
IPDI exists in two conformers, cis and trans. Their reactivities are similar and each conformer is an asymmetrical molecule with the secondary isocyanate group being more reactive than the primary isocyanate group. Since the substance does not contain any groups that might oxidize or spontaneously ignite, it is not expected that IPDI would self-ignite, oxidize, or explode at ambient conditions. The water solubility is approximately 15 mg l-1 at 23 ℃, and hydrolysis with a half-life of about an hour leads to polymers or to the corresponding diamine.

Yields polyurethanes with high stability, resistance to light discoloration, and chemical resistance.

Isophorone diisocyanate (IPDI) is used in theproduction of high-quality coatings, polyurethane paints, and varnishes and as an elastomer for casting compounds.

Isophorone diisocyanate is used in the manufacture of polyurethane with high stability, resistance to light discoloration and chemical resistance; used in paints and varnishes for hardness, flexibility, abrasion, chemical resistance to chalking and weathering; as an elastomer applicable for casting compounds and mastics to highly flexible textile coatings; foams; hard industrial coatings; manufacture of contact lenses; curing.
