Isophorone Diamine (IPDA)

IPDA
CAS 2855-13-2 · Formula C10H22N2 · MW 170.30 g/mol

A cycloaliphatic diamine serving both as a color-stable epoxy hardener and the route to IPDI. Industry references record its use as an epoxy hardener, as a chemical intermediate for the corresponding diisocyanate, and in the production of polymers, mainly polyurethanes.

Full Description

Isophorone diamine (CAS 2855-13-2) is a cycloaliphatic primary diamine used mainly as an epoxy resin curing agent and as the precursor to isophorone diisocyanate (IPDI). Industry references record its use as an epoxy hardener, as a chemical intermediate for the corresponding diisocyanate, and in the production of polymers, mainly polyurethanes. Supplied as a bulk amine intermediate.

Frequently Asked Questions

What is isophorone diamine used for?

Isophorone diamine (IPDA, CAS 2855-13-2) is used mainly as an epoxy resin curing agent (hardener) for coatings, flooring, and composites, and as the precursor to isophorone diisocyanate (IPDI). It is also a building block in the production of polymers, mainly polyurethanes. It is supplied as a bulk amine intermediate.

Is isophorone diamine an acid or base?

It is a base. IPDA is a cycloaliphatic primary diamine (formula C10H22N2) carrying two amine groups, which makes it basic and gives it its function as an epoxy hardener. Handle and store per the SDS.

What is the difference between IPDA and IPDI?

IPDA is the diamine (CAS 2855-13-2) and serves as a precursor; IPDI (isophorone diisocyanate, CAS 4098-71-9) is the corresponding diisocyanate made from it. IPDA is used as an epoxy hardener, while IPDI is used to build light-stable polyurethanes. We supply both as bulk intermediates.

How does IPDA ship under DOT and what is its UN number?

Isophorone diamine ships under UN 2289 (ISOPHORONEDIAMINE). Transport classification, packaging, and documentation follow the SDS and applicable transport regulations. We provide the SDS and shipping documentation with each shipment.

How is IPDA supplied in bulk and what is the cost?

We supply IPDA in bulk packaging such as drums and IBC totes, with a CoA and SDS per lot; the HS code is 2921.30. Pricing depends on volume and packaging, so request a current bulk quote with your quantity and ship-to.
