  • Applications

    1-Ethoxy-2-methyl-1-propoxypropane (CAS 238757-42-1) is a glycol ether that is commonly used as a polar solvent in coating, varnish, and ink systems, aiding dissolution of formulation components and resin compatibility. It also serves as a solvent or processing aid in cleaning formulations, degreasers, and industrial cleaners. As an intermediate in organic synthesis and polymer processing, it may participate in plastics and elastomer manufacturing. In electronics processing, it is used for cleaning and surface pretreatment of PCBs and components. Additionally, it can function as a component in adhesives and sealants formulations.
