Isophorone Diamine
A cycloaliphatic diamine: isophorone diamine's saturated ring structure resists yellowing and UV degradation that would affect aromatic curing agents, making it the preferred choice across epoxy, coatings and composite chemistry.
Chelora Chemicals supplies isophorone diamine to epoxy, coatings and polyurethane-precursor manufacturers worldwide, with full GHS documentation on every consignment.

What Isophorone Diamine is used for
Isophorone diamine (IPDA) is a colourless liquid supplied as an isomeric mixture, carrying two primary amine groups on a trimethyl-substituted cyclohexane ring. That cycloaliphatic backbone is the key to its value: unlike aromatic diamines, it does not yellow or degrade readily under UV exposure.
IPDA's largest-volume use is as an epoxy resin curing agent, prized in coatings and epoxy flooring for its low-yellowing, UV-stable cure. It is also the industrial precursor to isophorone diisocyanate (IPDI), a polyurethane building block, and is used across composite manufacture. Experimental research (including work at Tokyo Metropolitan University) has explored IPDA in CO₂-capture chemistry, though this remains an experimental application rather than an established industrial use.
Ring diamine versus simple ring amine
- Cyclohexylamine single amine on an unsubstituted ring — sweetener and rubber chemistry. See that page.
- Isophorone diamine (this product) two amine groups on a trimethyl-substituted ring — epoxy and polyurethane chemistry.
- Piperazine a different cyclic diamine, heterocyclic rather than carbocyclic. See that page.
Appearance and handling character
Isophorone diamine is corrosive — harmful if swallowed or in contact with skin, causes severe skin burns and eye damage, may cause an allergic skin reaction, and is harmful to aquatic life with long-lasting effects — a profile typical of reactive diamine curing agents.

How we supply Isophorone Diamine
Chelora Chemicals is a supplier and sourcing partner, not a manufacturer. IPDA's role as an epoxy curing agent means amine-value consistency matters as much as price — that shapes how we manage this line.
We place your order with whichever qualified producer best matches your required grade, your price point and your delivery window.
We keep a second qualified source on this line, so a single-plant disruption never becomes your production problem.
- Amine value confirmed before we quote. Consistency matters to downstream epoxy cure performance.
- UN 2289 logistics managed end to end. Classification, labelling and carrier compliance confirmed before booking.
- Sensitisation-hazard documentation filed correctly. Every shipment carries the correct hazard declarations.
- Scheduled call-off scheduling. We hold contracted tonnage and release it against your consumption calendar.
- Batch traceability to the producing plant. Full chain of custody documentation on request.
- Export machinery handled in-house. Classification, approved packing, labelling, freight booking and customs paperwork are ours to manage.

Corrosive, sensitising, and harmful to aquatic life
Isophorone diamine's combination of corrosivity and skin-sensitisation potential makes PPE and exposure control the central handling concerns. The summary below is orientation only — the safety data sheet supplied with your specific batch is the authoritative document.
Classified hazards
H302Harmful if swallowed.H312Harmful in contact with skin.H314Causes severe skin burns and eye damage.H317May cause an allergic skin reaction.H412Harmful to aquatic life with long-lasting effects.
Always read the SDS issued with your specific batch. Handle with chemical-resistant gloves, splash goggles and adequate ventilation; avoid skin contact to prevent sensitisation.
Storage
Store in tightly closed containers in a cool, dry, well-ventilated area, away from strong oxidisers and acids.
Handling
Use with local exhaust ventilation. Minimise skin contact with appropriate gloves and protective clothing to prevent sensitisation. Contain any spill and prevent release to drains or watercourses.
Transport
Shipped as UN 2289 in accordance with its corrosive classification. We confirm and document packing group and exact classification for your specific shipment and destination.
Every batch, documented
We verify documentation before dispatch so there are no surprises at your incoming-goods bench.

Documentation review
COA, SDS and transport paperwork checked by our desk before the shipment is booked.
Traceable dispatch
Each shipment is traceable to its producing batch, with full chain-of-custody records on request.
How isophorone diamine is made
Isophorone diamine is produced industrially starting from isophorone, via nitrile intermediate formation followed by hydrogenation, yielding the diamine as an isomeric mixture after purification and distillation.
We do not publish operating process parameters here; this is background only. Full technical and safety documentation accompanies every shipment, and any process-specific detail you need is best confirmed directly with our technical desk.
