Ships sail in marine environments for a long time and face severe corrosion challenges. Factors such as salt, humidity, temperature changes and microorganisms in seawater will accelerate the corrosion process of metal materials. In order to extend the service life of the ship and reduce maintenance costs, anti-corrosion coatings have become an important means of ship protection. DMAEE (dimethylaminoethoxy) plays a crucial role in marine anti-corrosion coatings as an efficient anti-corrosion additive. This article will discuss in detail the application, advantages and long-lasting protection effects of DMAEE in marine anti-corrosion coatings.
