Diisononylamine

Diisononylamine (CAS 28454-70-8) is a branched secondary amine used industrially as a corrosion inhibitor and surface-active agent.

Where is Diisononylamine used?

• Metalworking fluids and lubricant additives: corrosion inhibitor forming protective layers on ferrous and non-ferrous metal surfaces
• Coatings: surface modifier improving substrate adhesion and wetting on difficult surfaces
• Adhesives and sealants: reactive intermediate or cure promoter
• Plastics and polymers: processing aid or functional additive where controlled surface chemistry is required
• Its secondary amine structure makes it effective for metal protection and interfacial modification.

Good to know: Branching profiles can vary between producers, impacting performance in specific applications.

Commercial specifications

• Technical grade, purity specifications aligned to industrial end-use requirements
• Buyers for lubricant or coatings applications should confirm amine content and isomer distribution
