Isononylamine

Isononylamine (CAS 27775-00-4) is a branched-chain aliphatic primary amine used as a reactive building block and functional additive across industrial chemical manufacturing. Its primary amine group enables covalent bonding in curing systems, corrosion-inhibiting formulations, and surface-active chemistries for various industrial applications.

In epoxy coating and adhesive systems, it acts as a curing agent or co-curing component, contributing to crosslink density and adhesion to metal substrates. Lubricant and metalworking fluid formulators incorporate it as a corrosion inhibitor precursor, where it reacts with fatty acids to form protective amine salts.

In polymer and elastomer production, it serves as a reactive modifier for adjusting surface wettability or as an intermediate in synthesizing coupling agents. Coatings manufacturers also use it to prepare imidazoline or amide derivatives that function as film-forming corrosion inhibitors in industrial maintenance products.

This chemical is supplied as a liquid, typically at high purity levels suited for industrial synthesis and formulation work, meeting Technical grade standards. Purity specifications are commonly in the 98–99% range, and it is available in drum and IBC quantities, with bulk supply options for high-volume industrial users.
