For example, in the late 19th century, steel began to be widely used in the shipbuilding industry, but the subsequent corrosion problems greatly reduced the lifespan of many ships. According to historical records, a steel ship that has not been effectively treated with corrosion may only last for 5 to 10 years in marine environments.

To address this challenge, scientists are constantly looking for effective anti-corrosion methods. Early methods mainly relied on coating and cathode protection technologies. Although these technologies have achieved certain results, they often have problems such as inefficiency or difficulty in maintaining for a long time. Until the mid-20th century, a compound called Dioctyltin Dilaurate was introduced into the field of marine anti-corrosion, and it quickly became a star material in the industry for its outstanding performance.

Dioctyltin dilaurate, as an organotin compound, has significant corrosion resistance and stability, which makes it a key component in marine anticorrosion coatings. Its application not only extends the service life of the ship, but also greatly reduces maintenance costs. According to modern research statistics, the average life of ships using anticorrosion coatings containing dioctyltin dilaurate can be extended to more than 20 years, while reducing the maintenance frequency by about 30%.

Therefore, a deep understanding of the mechanism of action of dioctyltin dilaurate and its application in ship construction is crucial to improving the safety and economics of ships.
