Diisononylamine

Diisononylamine (CAS 28454-70-8) is a branched secondary amine used industrially as a corrosion inhibitor and surface-active agent. Its secondary amine structure makes it effective for metal protection and interfacial modification.

In metalworking fluids and lubricant additives, it functions as a corrosion inhibitor, forming protective layers on ferrous and non-ferrous metal surfaces to extend component service life across demanding industrial formulations.

Coatings formulators incorporate it as a surface modifier to improve substrate adhesion and wetting on difficult surfaces. In adhesive and sealant systems, it acts as a reactive intermediate or cure promoter.

This chemical contributes significantly to bond performance in polymer-based formulations. Plastics and polymer processors use it as a processing aid or functional additive where controlled surface chemistry is required.

Diisononylamine is supplied as a liquid, typical for secondary amines in this molecular weight range. Technical grade is the standard commercial offering, with purity specifications aligned to industrial end-use requirements.

Buyers sourcing for lubricant or coatings applications should confirm amine content and isomer distribution. Branching profiles can vary between producers, impacting the final performance of the chemical in specific applications.
