Cyanoethylated isophoronediamine is a modified cycloaliphatic amine hardener — an acrylonitrile (Michael) adduct of IPDA that extends pot life and reduces carbamation/blushing in ambient-cure epoxy coatings. Identity: CAS 93940-97-7.
What it is
This product (CAS 93940-97-7) is a liquid Michael adduct of isophoronediamine with acrylonitrile. Capping some amine hydrogens lowers reactivity and basicity, giving longer pot life and better appearance.
How it cures
The remaining amine hydrogens cure epoxy at ambient temperature with extended working time and reduced blush/carbamation (the surface haze amine hardeners can get in humid/cool conditions) — favored in coatings and flooring.
Applications
It is used in ambient-cure epoxy coatings and flooring needing low blush and longer pot life. The parent cycloaliphatic amine chemistry underlies many high-performance hardeners; see the epoxy curing agents guide.
Forms, grades and handling
Supplied as a clear-to-amber liquid in drums, IBCs and bulk. Properties are typical reference values; the Certificate of Analysis (CoA) for the lot you buy governs. Amine curing agents are typically corrosive and can sensitize skin — handle per the current Safety Data Sheet (SDS). Each lot ships with CoA, TDS and SDS.
Bulk supply and RFQ
RawSource sources Cyanoethylated Isophoronediamine direct from producers in bulk, with CoA, TDS and SDS per lot. Tell us your resin system, cure schedule (ambient or heat) and the properties you need (pot life, Tg, flexibility, chemical resistance), and we will quote the right hardener. See selection logic in the epoxy curing agents guide.

Frequently Asked Questions
What is cyanoethylated isophoronediamine used for?
Cyanoethylated isophoronediamine (CAS 93940-97-7) is a modified cycloaliphatic amine epoxy hardener (an IPDA-acrylonitrile Michael adduct) giving long pot life and low blush in ambient-cure coatings and flooring.
How is bulk cyanoethylated isophoronediamine supplied and quoted?
RawSource supplies cyanoethylated isophoronediamine in bulk with CoA, TDS and SDS per lot. Pricing is quote-based on grade and volume; submit an RFQ with your resin system and cure schedule.
What is the REACH and TSCA regulatory status of Cyanoethylated isophoronediamine (acrylonitrile / IPDA 1:1 Michael adduct)?
Cyanoethylated isophoronediamine (acrylonitrile / IPDA 1:1 Michael adduct) (CAS 93940-97-7) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 300-496-1).
