ARADUR 46-1S is a cycloaliphatic polyamine epoxy curing agent typically supplied as a proprietary mixture rather than a single chemical entity.
As a result, its primary chemical components (like modified polyamines) are often filed under variable CAS numbers depending on the exact formulation version.
For formulating and safety purposes, manufacturers primarily reference its main constituent CAS numbers, which usually fall into these categories:
Polyamine/Epoxide Adduct Polymer: 68410-23-1 (Common base for this type of adduct)
Cycloaliphatic Amine: 38294-64-3
Triethylenetetramine (TETA): 112-24-3
Aminoethylpiperazine (AEP): 140-31-8
