Key Features

Significant Synergistic Effects:KT551 exhibits significant synergistic effects in inhibiting the catalytic activity of metal ions—ions that typically trigger oil oxidation. This characteristic enhances the additive's protective capabilities, underscoring its importance across a wide range of oil-based applications.
Enhanced Antioxidant Capacity:KT551 boosts the antioxidant capacity of the oil, helping to prevent the formation of sludge, varnish, and other harmful byproducts resulting from oxidation. This ensures that the oil remains stable and effective over extended periods, thereby contributing to improved equipment performance and longer maintenance intervals.
Metal Surface Protection:KT551 forms an inert film on metal surfaces, effectively creating a protective barrier against oxidation and other detrimental reactions. This protective layer helps extend the service life of metal components, ensuring more efficient and reliable operation.
Synergy with Other Antioxidants:When used in combination with other antioxidants, KT551 demonstrates impressive synergistic effects, further enhancing both the protective qualities and overall performance of the oil. This makes it an excellent choice for maintaining oil quality and extending equipment longevity across diverse applications.

Function

Inhibition of Metal Ion Catalysis: The primary function of KT551 is to inhibit the catalytic effect of metal ions on oil oxidation. By mitigating this catalytic influence, KT551 preserves oil quality and helps prevent the formation of harmful byproducts.

Enhanced Antioxidant Protection: KT551 boosts the overall antioxidant capacity of oils, ensuring they remain stable and effective over extended periods. This helps extend maintenance intervals, improve equipment performance, and prolong service life.

Prevention of Metal Oxidation: By forming an inert film on metal surfaces or chelating with metal ions, KT551 effectively prevents the oxidation of various metals. This contributes to extending component lifespan and enhancing overall equipment efficiency.

Application

Industrial Lubricants: KT551 can be incorporated into various industrial lubricants—such as gear oils, compressor oils, hydraulic fluids, and slideway oils—to enhance their oxidation resistance and prevent metal oxidation. This ensures that equipment and machinery operate smoothly and efficiently over extended periods.

Automotive Lubricants: In the automotive sector, KT551 is utilized in engine oils, transmission fluids, and gear oils to bolster oxidation protection and prevent the oxidation of metal components. This contributes to improved fuel efficiency, reduced emissions, and an extended service life for automotive systems.

Marine Lubricants: Within the harsh environments of the marine industry, KT551 serves as an ideal additive for marine lubricants—such as cylinder oils and hydraulic fluids—which require protection against oxidation and metal degradation when exposed to seawater or fluctuating temperatures and humidity levels.

Greases: KT551 is suitable for use in a wide range of greases requiring enhanced oxidation protection or the prevention of metal oxidation, including general-purpose, high-temperature, extreme-pressure, and marine or industrial greases. This additive helps ensure that grease formulations deliver effective lubrication and corrosion-inhibiting properties across diverse applications.
