  • Applications

    Butyl propionate (CAS 590-01-2) is a pleasant-fruity ester widely employed as a medium-evaporation solvent in nitrocellulose automotive lacquers, alkyd coatings, varnishes, printing inks and adhesive diluents, where it enhances flow, gloss, leveling and drying speed; its balanced polarity enables it to dissolve both polar and non-polar resins, making it valuable in two-component polyurethane systems, epoxy primers, industrial spray inks, metal cleaners and paint strippers, while its mild odour allows use as a fragrance diluent, food flavouring agent, pharmaceutical excipient and intermediate for plasticizers, surfactants and active ingredients; the compound is further appreciated for its low VOC contribution, subtle smell and favourable toxicological profile, helping formulators comply with increasingly stringent environmental and occupational health regulations.
