Introduction to five product systems of marine coatings

At present, the antifouling coatings used on ships are antifouling coatings that use cuprous oxide as the antifouling agent, and are divided into long-term antifouling coatings and self-polishing antifouling coatings.
The former must be launched as soon as possible after the construction is completed, otherwise it will crack, while the latter does not have these restrictions.
From the perspective of usage, long-term antifouling coatings are suitable for ships and offshore installations with low sailing rates, while self-polishing antifouling coatings are suitable for ships with relatively fast sailing speeds and high sailing rates.
Since cuprous oxide is still toxic to the human body, it is only allowed to exist as a transitional product in the world, and its use will be gradually banned in the future.
The development of a new generation of antifouling coatings has achieved initial results, but from the perspective of marketed products, it is generally expensive, difficult to construct, and narrow in scope of use.
It is difficult to adapt to the requirements of large-scale shipbuilding.

Special functional coatings

Special functional coatings came into being with the deepening of the marine market, including oil tank coatings, fireproof coatings, chemical tank coatings and high temperature resistant coatings.
In most cases, these coatings are custom-produced according to the specific conditions of the cabin and the difference in the load.

At present, the commonly used special coatings are mainly produced by using epoxy resin as the matrix and adding special additives (such as oil-resistant paints for oil tanks).
For example, aluminum powder is used as an additive in general temperature-resistant coatings to achieve a certain temperature-resistant effect; for harsh environments, special coatings should be selected, such as silicone coatings as high-temperature coatings.

Nowadays, most of the marine coatings market is still controlled by foreign companies, such as international coatings, Kansai coatings, PPG coatings and other large multinational companies; while local companies only occupy a small share, such as Shanghai Kailin, Xiangjiang Paint, Jiangsu Jinling For local well-known paint companies, the only way for local companies to catch up with foreign companies is to "practice their internal skills", increase scientific and technological research and development and improve the training mechanism of scientific and technological talents.
