Solvent Applications
Isophorone is an effective high-boiling solvent for a wide range of resins, including vinyls, epoxies, and acrylates. Its slow evaporation rate makes it suitable for coatings, inks, and adhesives where controlled drying times are necessary.
Chemical Synthesis Intermediate
As a cyclic ketone, Isophorone is a crucial building block in organic synthesis. It is used in the production of isophorone diamine (IPDA) and isophorone diisocyanate (IPDI), which are monomers for high-performance polyurethanes and epoxy curing agents.
Pesticide and Herbicide Formulations
It finds utility as a solvent and co-solvent in the formulation of certain agricultural chemicals, aiding in the dissolution and application of active ingredients.
Fragrance and Flavour Industry
While less common, Isophorone derivatives can be employed in the synthesis of compounds used in the fragrance industry due to their specific olfactory characteristics.
