Protective Coating For The Marine Sector

Why the Marine sector needs protective coatings?

Marine environments are among the harshest on the planet, with constant exposure to saltwater, humidity, and extreme weather conditions. Ensuring the durability and performance of marine equipment and structures requires high-quality coatings designed to resist corrosion, abrasion, and environmental wear.

At Northpoint, we provide advanced protective coating for the marine sector including safeguarding vessels, offshore platforms, and other marine assets for long-term reliability.

Our protective coating for the marine sector is engineered to extend the lifespan of marine assets, reduce maintenance needs, and ensure performance in even the most challenging conditions. It is vitally important to understand the function of the coating chosen for protecting anything in the sector as getting it wrong or cutting corners can reduce the life expectancy of items by years.

ISO 12944 is a great place to start in order to determine the required level of protection. If you would like to speak to us about your project whether it’s a ship part being repaired in wet paint or coastal infrastructure that needs powder coating, we can work to a variety of specifications and through our trusted network of paint and powder suppliers can recommend suitable coating systems to ensure your items last.

ISO 12944-2 Tab. 1 – Categories of Corrosion
Category of corrosion
C1 – Very Low	Very little or no pollution. Heated buildings, offices, shops, schools, hotels etc.
C2 – Low	Low levels of pollution. Mostly rural areas.
C3 – Medium	Urban and industrial areas, moderate sulphur dioxide pollution. Coastal areas with low salinity [not under direct influence of salty air/wind]
C4 – High	Industrial areas and coastal areas with moderate salinity. Sea front areas
C5 – I Very High	Industrial areas with high levels of humidity (Middle East)
C5 – M Very High	Coastal and offshore areas with high salinity. Sea front protection barriers, oil rigs.
CX – Very High	Marine and offshore environments.

Process Northpoint would go through to coat

Our specialised coating process is designed to meet the high standards of the automotive industry, providing protection and performance for every component.

Here’s how we achieve exceptional powder coating results:

=

1. Surface Preparation

Marine components are thoroughly cleaned to remove contaminants, rust, and old coatings. Pre-treatment processes are utilised to create an optimal surface for coating adhesion, ensuring durability and resistance to marine-specific challenges.

=

2. Masking and Inspection:

Areas that must remain uncoated are carefully masked, and every component is inspected to ensure proper preparation before coating application.

=

3. Powder Application

Using industry-leading techniques, we apply advanced coatings tailored to provide superior resistance to saltwater, UV rays, and mechanical wear. Our coatings are designed to protect both submerged and above-water structures, ensuring comprehensive durability. Additionally, we offer state-of-the-art wet paint coating solutions, utilising cutting-edge wet paint booths to deliver precise, high-quality finishes that meet the most demanding specifications.

=

4. Curing

The coated components are cured through precise methods to create a robust, seamless protective barrier. This process enhances resistance to corrosion, impact, and the extreme conditions typical in marine environments.

=

5. Quality Assurance

Each item undergoes detailed inspection to verify uniform coverage, adhesion, and compliance with marine industry standards, ensuring the highest levels of performance and protection.

=

6. Delivery

After passing our stringent quality checks, the coated components are securely packaged for transport and are ready for deployment in demanding marine applications.

Our coating solutions are engineered to extend the lifespan of marine assets, reduce maintenance needs, and ensure performance in even the most challenging conditions.
