Where is 2-heptanone used?
- Coatings and industrial cleaning: dissolves nitrocellulose, acrylics and vinyl resins, with slower evaporation that improves flow and leveling in spray-applied finishes
- Metalworking and lubricants: carrier solvent aiding deposition of active compounds onto metal surfaces
- Personal care: solvent and fragrance ingredient in nail care, hair preparations and skin formulations
- Food: flavoring agent imparting fruity, cheese-like or banana notes in baked goods, dairy products and beverages
- It delivers strong solvency for resins and coatings while contributing a fruity, banana-like character.
Commercial specifications
- Technical grade for solvent and metalworking applications
- Clear liquid in drums and IBC totes for bulk industrial procurement
