As a high-performance synthetic lubricant, ethyl silicone oil has excellent lubrication and dielectric properties, as well as a wide operating temperature range, low temperature viscosity coefficient, low volatility, and is non-toxic and non-corrosive. However, there is currently no direct information or research on the anti-corrosion effect of ethyl silicone oil lubricants in ships and marine engineering, indicating its specific effect as an anti-corrosion agent. However, based on the characteristics of ethyl silicone oil, it can be inferred that it may have an auxiliary anti-corrosion effect in these environments:

Excellent lubrication performance: Ethyl silicone oil can effectively reduce friction between mechanical parts, thereby reducing the risk of wear and corrosion. In mechanical equipment in ships and marine engineering, good lubrication can reduce direct contact between parts and prevent corrosion caused by heat and wear generated by friction.
Chemical stability: Ethyl silicone oil has excellent chemical stability and can maintain its performance unchanged under extreme conditions. In the marine environment, ordinary lubricants may fail quickly due to the erosion of salt spray, seawater and other corrosive substances. Ethyl silicone oil, due to its stable chemical properties, can better resist the erosion of these corrosive substances.
Temperature resistance: Ethyl silicone oil can maintain fluidity in a wide temperature range of -60℃150℃ (or -70℃150℃), which means that it can maintain a stable working state in the complex temperature environment of ships and marine engineering. This temperature resistance helps prevent lubricant failure and corrosion problems caused by temperature changes.

Electrical insulation performance: Although this is not directly related to the direct anti-corrosion effect, the electrical insulation performance of ethyl silicone oil can ensure the safety of use in electrical equipment and systems and reduce corrosion problems caused by electrical failures.
Despite the above advantages of ethyl silicone oil, it should be noted that it is not a special anti-corrosion agent in itself. In ships and marine engineering, corrosion protection usually relies on special anti-corrosion coatings, metal sealing protective layers and non-metallic "sealing" and other anti-corrosion process technologies and measures. Ethyl silicone oil lubricants may mainly play a role in lubrication and wear reduction in these environments, thereby indirectly helping to reduce the risk of corrosion caused by friction and wear.

Therefore, in ships and marine engineering, if ethyl silicone oil is to be used as a lubricant, it is recommended to use it in combination with other anti-corrosion measures to achieve the best anti-corrosion effect. At the same time, it is also necessary to pay close attention to the use of ethyl silicone oil lubricant, and conduct regular inspections and maintenance to ensure that it can continue to play its role in lubrication and corrosion reduction.
