On the vast ocean, ships shuttle back and forth like steel giants, carrying the heavy responsibility of global trade and human exploration. In the design, construction and operation of ships, ship additives play an indispensable and important role.

There are many types of ship additives, covering many fields such as anti-corrosion, anti-fouling, lubrication, cleaning, etc. Each additive has its unique function and role, and together contributes to the stable operation of the ship. In the following article, we will introduce the types and functions of ship additives.

The following table is epoxy marine additives:

	Dispersants	Defoaming agent	Leveling agent	Anti-sagging agent
Primer & Midcoat	CFC-500HP / CFC-510	Depol CFC-165 / Depol CFC-192	Slip CFC-700 / Slip CFC-706  / Slip CFC-710	CIMA 240-20 / CIMA-320P / CIMA-1400
Topcoat	CFC-500HP / CFC-604S	Depol CFC-126F / Depol CFC-166H	Slip CFC-700 / Slip CFC-720 / Letch CFC-84	CIMA 240-20 / CIMA-320P / CIMA-1400

Epoxy marine additives have significant advantages. They have strong anti-corrosion properties and can effectively block corrosive media; they have excellent anti-fouling properties and can reduce biofouling; they have good mechanical properties and are wear-resistant and impact-resistant; they have strong environmental adaptability, are water-resistant and weather-resistant, and have high chemical stability, providing strong guarantees for the safe and efficient operation of ships.

The following table shows the classification and application of different polyurethane additives in marine applications：

	Dispersants	Defoaming agent	Leveling agent	Anti-sagging agent
Primer & Midcoat	CFC-510 / CFC-580 / CFC-6330N	Depol CFC-165 / Depol CFC-192	Slip CFC-710 / Letch CFC-89	CIMA-320P / CIMA 240-20 / CIMA-1400
Topcoat	CFC-510 / CFC-580 / CFC-6330N	Depol CFC-126F / Depol CFC-166H	Slip CFC-710 / Letch CFC-89	CIMA-320P / CIMA 240-20 / CIMA-1400

Polyurethane marine additives have many advantages. They have good wear resistance and impact resistance to protect the hull; strong corrosion resistance to resist seawater erosion; good adhesion, the coating is not easy to fall off; good flexibility to adapt to hull deformation; also has a certain degree of weather resistance, extending the service life of the ship.
