  • Applications

    Propylcyclohexane (CAS 1678-92-8) may be used as a non-polar solvent and processing aid in industrial manufacturing. It is commonly evaluated as a diluent for coatings and inks to adjust viscosity and improve flow, and as a solvent in adhesive formulations. It can serve as a degreasing/ cleaning solvent in maintenance and industrial cleaning applications. In polymer and plastics processing, it may act as a processing solvent or diluent for specialty resins and formulations. It also may be an intermediate in organic synthesis for the preparation of more complex chemicals. All uses are subject to local regulations and formulation limits.
