Isophorone diisocyanate (CAS 4098-71-9) is a cycloaliphatic diisocyanate used to produce light-stable polyurethane coatings, varnishes, and elastomers. Industry references record its resistance to light discoloration and chemical attack, and it is used in powder coatings and one-component polyurethane enamels. Supplied as a bulk isocyanate intermediate and as IPDI-based polyisocyanate hardeners.
Frequently Asked Questions
What is isophorone diisocyanate used for?
Isophorone diisocyanate (IPDI, CAS 4098-71-9) is a cycloaliphatic diisocyanate used to produce light-stable, non-yellowing polyurethane coatings, varnishes, and elastomers. It is used in powder coatings and one-component (1K) polyurethane enamels, valued for resistance to light discoloration and chemical attack. We also supply IPDI-based polyisocyanate hardeners.
What is the IPDI trimer?
The IPDI trimer is the isocyanurate (polyisocyanate) derived from IPDI, used as a hardener/crosslinker in two-component polyurethane coatings and powder coatings. It offers higher functionality and lower volatility than the monomer while retaining light stability. We can supply IPDI-based polyisocyanate hardeners on request.
How does IPDI ship under DOT and what is its UN number?
Isophorone diisocyanate ships under UN 2290 (ISOPHORONE DIISOCYANATE). Transport classification, packaging, and handling follow the SDS and applicable transport regulations, which we provide with each shipment.
What is the CAS number and HS code for IPDI?
The CAS number is 4098-71-9 and the molecular formula is C12H18N2O2. The HS classification is 2929.10 (isocyanates). Lot-specific identity and specification are confirmed on the Certificate of Analysis.
How is IPDI supplied in bulk and what is the cost?
We supply IPDI in bulk industrial packaging such as drums and IBC totes, with a CoA and SDS per lot. Pricing is volume- and packaging-dependent; request a current bulk quote with your target quantity and ship-to.
