Marine Paint Brands in Nigeria: PPG Sigma, Jotun, International and Hempel Compared

Choosing a marine paint system is an important part of protecting vessels, marine structures and equipment from corrosion, seawater exposure, weathering, abrasion and other demanding operating conditions. However, selecting a marine coating is not simply a matter of choosing a well-known brand. The right product depends on the vessel area, operating environment, surface condition, coating system and performance requirements.

Several established coating manufacturers offer marine and protective coating technologies for different applications. In Nigeria, Morven Industrial supplies marine and protective coating products from brands including PPG Sigma, Jotun, International Paint and Hempel.

This guide compares these marine paint brands based on the types of products and applications relevant to vessel protection, maintenance and industrial marine coating projects. The purpose is not to declare one brand the overall best, but to help buyers understand the differences between coating systems and select products according to their specific requirements.

What Should You Consider When Comparing Marine Paint Brands?

Before comparing brands, it is important to understand what makes one marine coating suitable for a particular application. A vessel contains different areas with different exposure conditions. The underwater hull, topsides, decks, superstructure, ballast tanks and cargo areas may all require different coating systems.

Important factors to consider include:

• The area of the vessel being coated
• Whether the surface is above or below the waterline
• Exposure to seawater, salt spray and moisture
• Corrosion and abrasion requirements
• Existing coating condition
• Surface preparation requirements
• Immersion or atmospheric exposure
• Required primer, intermediate and finishing coats
• Application method and environmental conditions
• Maintenance and recoating requirements

A complete coating system should therefore be considered rather than selecting a product based only on the brand name.

PPG Sigma Marine Paints

PPG Sigma is one of the marine and protective coating product families available through Morven Industrial. The range includes epoxy primers and protective coatings designed for different marine and industrial applications.

For example, PPG SigmaCover 350 is a two-component, high-build polyamide-cured anticorrosive epoxy primer/coating. Morven’s product information lists applications including topsides, decks, superstructures and cargo holds, with use on steel and concrete.

Another product, PPG SigmaCover 280, is a universal epoxy anticorrosive primer listed for applications including ballast tanks, decks, topsides, superstructures, hulls and cargo oil tanks.

Morven’s Sigma range also includes products such as SigmaCover 456, SigmaCover 630, SigmaCover 620, SigmaCover 380, Sigmadur 550 and Sigmatherm products for other protective coating requirements.

This makes the Sigma range relevant when a project requires different coating technologies for different areas rather than a single universal marine paint.

Jotun Marine Paints

Jotun is another major coating brand represented in Morven Industrial’s marine and protective coating range. Jotun offers coating technologies for marine, offshore and industrial applications, with product selection depending on the vessel area and service environment.

One of the Jotun products available from Morven is Jotamastic 90. It is a two-component polyamine-cured epoxy mastic designed primarily for repair and maintenance. Morven’s product information describes it as surface tolerant, high solids and high build.

Jotamastic 90 can be used as a primer, midcoat, finish coat or single-coat system in specified atmospheric and immersed environments. Its listed marine applications include outside hulls and exterior and interior areas.

Morven also carries JOTAMASTIC 87 and Jotamastic 70. These products are part of the maintenance-coating segment of the Jotun range and can be relevant where surface preparation and maintenance conditions influence coating selection.

Jotun’s official marine product information also demonstrates that coating selection varies according to vessel type and application rather than being based on a single product for every marine project.

International Paint

International Paint is another important marine coating brand in Morven’s catalogue. Its product range includes primers, epoxy coatings, polyurethane finishes, tank linings and other protective coating technologies.

For above-water vessel areas, Interthane 990 is a two-component acrylic polyurethane finish listed by Morven for applications including boot tops, exterior superstructures, external decks and topsides.

For anticorrosive protection, Morven also lists products such as Interzinc 52 and Interzinc 22. These are zinc-rich primer technologies intended for specified protective coating systems.

International’s range also includes products for tank lining and other marine applications. For example, Interline 850 is an epoxy phenolic coating listed for tank lining applications and new construction or maintenance and repair.

The main point when evaluating International Paint is therefore to look at the specific product and coating system rather than treating the entire brand as a single type of marine paint.

Hempel Marine Paints

Hempel offers marine and protective coating technologies covering different areas of vessel protection and maintenance. Hempel’s marine portfolio includes solutions for underwater hulls, topsides, newbuilding, dry docking and maintenance applications.

Morven Industrial currently carries Hempel products within its Painting and Protective Coating category.

One example is Hempadur Mastic 45880, a polyamide-curing, high-solids epoxy paint. Morven’s product information describes it as a hard and tough coating with good wetting properties and low-temperature curing characteristics.

It can be used as a self-primed, surface-tolerant system or as an intermediate or finishing coat in heavy-duty coating systems where the product’s specified conditions are appropriate.

Other Hempel products available through Morven include Hempadur 15570, Hempalin Primer 12050 and Hempathane Topcoat 55210, providing options across different protective coating requirements.

PPG Sigma vs Jotun vs International Paint vs Hempel

Instead of asking which brand is the best overall, marine coating buyers should compare the brands according to the specific project requirements.

This comparison should be used as a starting point rather than as a substitute for the manufacturer’s technical documentation. Product selection should be based on the actual vessel area, exposure conditions and coating specification.

How to Choose the Right Marine Paint

When selecting marine paint, start by identifying exactly what needs to be protected.

1. Identify the Vessel Area

Determine whether the coating will be applied to the underwater hull, topside, deck, superstructure, ballast tank, cargo area or another part of the vessel.

2. Determine the Exposure

Consider whether the surface will experience continuous immersion, intermittent exposure, salt spray, sunlight, abrasion, impact, chemicals or other environmental conditions.

3. Assess the Existing Surface

For maintenance projects, determine the condition of the existing coating and substrate. Rust, loose coating, contamination and previous coating systems can affect the preparation and product selection requirements.

4. Select the Complete Coating System

A marine coating project may require a primer, intermediate coat and finishing coat. These products should be compatible and applied according to the manufacturer’s technical requirements.

5. Review Application Conditions

Temperature, humidity, surface condition, dew point, ventilation and application method can affect coating application and curing. Always follow the relevant product technical data sheet.

Why Surface Preparation Matters

Even a high-performance marine coating can perform poorly if the surface is not properly prepared.

Depending on the coating system and substrate condition, preparation may involve abrasive blasting, power-tool cleaning, washing or other approved methods. The objective is to remove contaminants and create the surface condition required by the coating specification.

For example, Morven’s PPG SigmaCover 350 product information provides different surface preparation requirements depending on whether the steel is blast cleaned, power-tool cleaned or previously coated.

Surface preparation should therefore be treated as part of the coating system rather than as a separate step.

Marine Paint Brands and Vessel Protection in Nigeria

Marine operators, shipyards, vessel owners and industrial companies in Nigeria may require coatings for new construction, dry-dock maintenance, repairs, corrosion control and general vessel maintenance.

Morven Industrial’s Painting and Protective Coating category provides access to marine and protective coating products from PPG Sigma, Jotun, International Paint and Hempel.

The appropriate product will depend on the vessel, surface condition, exposure and coating specification. Buyers should therefore provide sufficient information about the intended application when requesting a coating recommendation or quotation.

Final Thoughts

PPG Sigma, Jotun, International Paint and Hempel all offer marine and protective coating technologies for different applications. However, there is no single marine paint product that is automatically suitable for every vessel or every part of a vessel.

The most important consideration is matching the coating system to the application. Vessel area, exposure, substrate condition, surface preparation, coating compatibility, application conditions and maintenance requirements should all be considered before a product is selected.
