    Product Applications
    • Emulsification and Corrosion Inhibition: Aristonate® H provides excellent emulsification and corrosion inhibition properties in hydraulic fluids, waterproof grease, heavy-duty extreme pressure oils and water-in-oil emulsion formulations. Aristonate® H also imparts corrosion protection to metal parts exposed to water, such as in high water-based coolants, high water based hydraulic fluids, drawing compounds, rolling oils and cutting oils.
    • Soluble Oils: Aristonate® H is the corrosion inhibitor of choice for high water based cutting fluids and simple soluble oils for the metalworking industry. Aristonate® H imparts maximum corrosion protection to metal parts through machining while maintaining excellent cooling and lubrication properties. Aristonate® H also provides maximum part adhesion during machining permitting maximum shelf storage life.
