Marine Heavy Zinc-Rich Epoxy Anti-Corrosion Coating

Product features:

This marine heavy zinc-rich epoxy anti-corrosion coating stands out with its 85% high-purity zinc content, providing active cathodic protection to prevent rust even when the coating has minor scratches or damage. Its 2000-hour seawater corrosion resistance ensures long-term protection for ship hulls and offshore platforms in harsh marine environments. The coating can be applied via airless spray, with a fast curing time of 12 hours at 25°C, reducing construction time for marine engineering projects. It offers optional anti-fouling additives to prevent marine organism attachment and self-healing properties that can repair minor coating damage automatically. Unlike traditional zinc-rich coatings that have poor adhesion and easy peeling, this product has excellent bonding strength with steel substrates, maintaining protective performance for long-term marine use.

Product specifications:

Key specifications include a zinc content of 85% by weight, dry film thickness ranging from 150 to 200 microns, and a curing time of 12 hours at 25°C. It has a temperature resistance range from -10°C to 80°C, making it suitable for both cold deep-sea environments and tropical coastal areas. The coating is available in 20-liter industrial drums, with options for anti-fouling and self-healing formulations. It meets strict environmental standards with VOC content below 45 g/L, and its adhesion strength to steel substrates exceeds 35 N/cm. Additional features include active cathodic protection performance and excellent compatibility with steel, cast iron and FRP substrates.

Product application:

This coating is ideal for marine metal structures, including ship hulls, offshore drilling platforms, port steel cranes, coastal wind power towers and seawater transmission pipelines. It is suitable for both new ship construction and retrofitting existing corroded marine equipment, helping marine engineering enterprises reduce long-term maintenance costs and extend the service life of their metal assets by up to 15 years. The coating’s active cathodic protection technology makes it a reliable choice for marine projects that require long-term corrosion protection in high-salt spray environments.
