Applications
1. Solvent And Diluent For Coatings: It is used as a solvent or diluent in coil coatings, baking varnishes, tinplate coatings, automotive coatings, wood coatings and insulating coatings, where a high boiling point and even evaporation suit the drying profile of an oven cured film.
2. Ink Solvent Replacing Isophorone: In ink formulations it can replace the high boiling solvent isophorone, which is more toxic and carries a strong odour, while still providing the solvency that the resin system needs.
3. Paint Stripper And Coating Remover: It works as the active solvent in paint strippers and coating removers for industrial and automotive refinishing, and patents describe stripper compositions built on dibasic ester as a low toxicity substitute for chlorinated and NMP based systems.
4. Industrial Cleaning Solvent: Its solvency lifts paints, inks, greases and resins from equipment and surfaces, which makes it a working solvent in industrial cleaning and parts washing formulations.
5. Non-HAP And Readily Biodegradable Positioning: Dibasic ester is supplied as a non-HAP, readily biodegradable oxygenated solvent, which is why formulators reach for it when moving away from higher hazard solvents in coatings, inks and cleaners.
