Uses

【Use 1】Mainly used as a solvent, dispersant, and diluent; also used as a fuel antifreeze and extractant.

【Use 2】1-Methoxy-2-propanol is an intermediate in the herbicide metolachlor.

【Use 3】Used as a solvent, dispersant, or diluent in the coatings, inks, printing and dyeing, pesticides, cellulose, and acrylate industries. Also used as a fuel antifreeze, cleaning agent, extractant, and non-ferrous metal beneficiation agent. Also used as a raw material in organic synthesis.

【Use 4】Propylene glycol methyl ether (107-98-2) is mainly used as an excellent solvent for nitrocellulose, alkyd resins, and maleic anhydride-modified phenolic resins; used as an antifreeze for jet engines and an additive for brake fluids; used as a solvent for inks, textile dyes, and textile oils; water-based coatings made from it are widely used in the automotive industry.

【Use 5】Propylene glycol methyl ether (107-98-2) is widely used in coatings and cleaning agents. Specific applications include: active solvent for water-based coatings; active solvent and coupling agent for solvent-based printing inks; solvent for ballpoint pen and fountain pen inks; coupling agent and solvent for household and industrial cleaners, rust removers, and hard surface cleaners; solvent for agricultural pesticides; and formulations for glass cleaners when mixed with propylene glycol n-butyl ether.

【Use Six】As a solvent, dispersant, or diluent in coatings, inks, printing and dyeing, pesticides, cellulose, acrylates, and other industries. It can also be used as a fuel antifreeze, cleaning agent, extractant, and non-ferrous metal beneficiation agent. It can also be used as a raw material for organic synthesis.
