Propylene Glycol Monobutyl Ether (PNB) is a colorless, transparent, low-viscosity liquid with a mild ether-like odor. It is a high-boiling-point, environmentally friendly organic solvent widely used in coatings (film-forming agent), inks (solvent carrier), cleaners (stain-removing enhancer), textiles (dye dispersant), as well as in metalworking fluids (anti-rust additive), chemical intermediates (synthesis reaction medium), and brake fluids (main component).
