Maxtop anti-rust turbine oil is formulated from deeply refined base oil and additives such as antioxidants, anti-rust agents, metal passivators, anti-emulsifiers, and anti-foaming agents. It has good anti-emulsification properties and higher requirements for oxidation resistance, as well as good rust resistance.
