Product Applications
1-Methoxy-2-propanol is widely used in the production of lacquers and paints, as an antifreeze agent in industrial engines, and as a tailing agent for inks used in high-speed printing presses. It also serves as a coupling agent for resins and dyes in water-based inks and as a solvent for cellulose derivatives, acrylic resins, dyes, inks, and stains. Additionally, it is used in various cleaning products, including glass and carpet cleaners, carbon and grease removers, and paint and varnish strippers. In agricultural applications, it functions as a solvent in pesticide formulations intended for use on crops and animals.
