Crown Brand Marine Paint ~ Marine Anticorrosive Paint (Supplied in Sichuan, Chengdu, Yunnan, etc.) - Custom Processing by Koguan Factory; Custom Paint Products 152^0825^6966 Manager Sun; What is Marine Paint? Marine paint is a special coating designed specifically for ships and offshore engineering, applied to parts such as the hull, deck, and cabins. Its main functions include:
Anticorrosion and Antirust: Resists erosion from seawater and salt spray, extending the ship's lifespan.
Antifouling and Drag Reduction: Prevents attachment of marine organisms (such as barnacles, algae), reduces sailing resistance, and saves fuel.
Aesthetics and Identification: Provides color and gloss, meeting the appearance and marking needs of ships.

Key Types of Marine Paint
Primer: Directly contacts the steel plate, providing basic anticorrosion (e.g., epoxy zinc-rich primer).
Antifouling Paint: Contains bioactive ingredients to inhibit marine organism attachment (e.g., self-polishing antifouling paint).
Topcoat: Strong weather resistance, protects the underlying layers and enhances appearance (e.g., polyurethane topcoat).

Why is Marine Paint Important?
Economy: Reduces maintenance costs and avoids huge losses caused by corrosion.

Environmental Friendliness: Modern marine paints tend to use low-toxicity, heavy-metal-free formulas to protect the marine ecosystem.

Performance Improvement: Advanced antifouling technology can increase sailing speed by 5%-10%, significantly reducing fuel consumption.

Marine Anticorrosive Paint Application is a key step in protecting the hull from seawater corrosion. The main process includes:

Surface Treatment: Treat rust, old paint, and contaminants through methods like sandblasting and grinding to ensure the steel plate reaches Sa2.5 cleanliness (ISO standard).

Primer Coating: Spray epoxy zinc-rich or inorganic zinc silicate primer to form a dense anticorrosion layer and enhance adhesion.

Intermediate Coating: Apply intermediate coats like epoxy mica iron oxide to fill pores and improve coating thickness and impermeability.

Topcoat Application: Choose polyurethane or fluorocarbon topcoat to provide weather resistance, UV resistance, and aesthetic effects.

Application should be carried out in suitable temperature and humidity conditions (usually 5°C~35°C). Each coat needs to cure, and work should avoid rainy or foggy weather. Professional spraying equipment (such as airless spray) can improve uniformity and efficiency. Standardized application can extend the ship's lifespan by over 10 years and reduce maintenance costs.
