Product Uses
  • NA-SUL® ZS-HT is an excellent rust and corrosion inhibitor when used in a variety of petroleum and synthetic lubricants. NA-SUL® ZS-HT is ideally suited for formulating hydraulic oils, circulating oils and gear oils where good anticorrosion, hydrolytic and thermal stability as well as outstanding demulsification properties are required. NA-SUL® ZS-HT performs very well in both acidic and neutral conditions.
  • In lubricant oxidation tests, NA-SUL® ZS-HT is compatible with a wide range of additives and is synergistic with commonly used aminic and phenolic oxidation inhibitors in polyalphaolefin base fluids. NA-SUL® ZS-HT also enhances EP/AW performance when used in combination with ZnDTPs.
