  • Applications

    Dibutoxymethane (CAS 2568-90-3) is used primarily as a solvent and co-solvent in coatings, inks, and adhesives, helping dissolve formulation components and adjust rheology. It serves as a processing solvent and aid in the production of plastics and polymers, supporting mixing, dispersion, and film formation. It can act as an intermediate in organic synthesis, particularly in acetal- and ether-based chemistry. It is employed in industrial cleaning formulations to dissolve oils, greases, and other contaminants. It may be used as a component in specialty resin and polymer formulations to influence volatility and solvency characteristics.
