Marine coatings are a specialized market, designed to protect ships, leisure boats, docks, containers, and more. In addition to enhancing aesthetic appearance, these coatings must also address corrosive degradation, as well as biofouling concerns, such as marine organisms adhering to the surface.
The marine coatings market will be worth $10.4 billion by 2019,1 and $15 billion by 2024.2 Further, demand is growing in Asia-Pacific, and China specifically, due to shipbuilding and dry-docking. Anti-corrosive coatings account for the largest share of the market, followed by anti-fouling coatings.1

Anti-corrosive marine coatings
Corrosion control in marine coatings helps protect vessels, equipment, and structure from damage, often associated with abrasion, impact, or chemical contact.
The majority of marine coatings are made with petrochemical derivatives, such as benzene, toluene, ethylene, and naphthalene. However, increasingly strict environmental legislation – specifically around volatile organic compounds (VOCs) — is likely to negatively impact use of these materials. This trend will continue as consumers demand more eco-friendly products. At the same time, demand for waterborne formulations will offer new product development opportunities.3
Epoxy coatings are commonly used for marine purposes, as they provide superior corrosion control, as well as water, alkali, and acid resistance. They also work well on both metal and concrete.3
In addition to their anti-corrosive properties, polyurethane marine coatings offer a variety of color options, as well as a traditional glossy appearance.3
Coatings Tech reports4 an increased demand for new technologies that address specific issues, such as high-performance epoxy resins and polymers designed for corrosion control.
Anti-fouling marine coatings
Algae, plants, bacteria, barnacles – all these, and other organisms can find a home on marine vessels and structures. In fact, unwanted organisms can settle on surfaces within 60 seconds, if the surface isn’t properly coated.5 These organisms require specific conditions to survive and thrive, such as:
- Sunlight (and thereby, energy, via photosynthesis)
- Specific temperature range
- Suitable surface6
A vessel with heavy bioaccumulation can suffer from higher fuel costs due to drag, and increased emissions, so protective coatings are extremely critical to the marine market.
Anti-fouling marine coatings help make surfaces inhospitable to biofouling, often through the use of biocides. The use of smart materials can help create this unfriendly environment, creating a slick film, or releasing a biocide when seawater comes in contact with the coated surface.7
The EU Biocidal Products Regulation (BPR) will impact the development and availability of new biocides, as they are costly to test and produce, if not already registered for use in another sector.7 The European Chemicals Agency maintains a searchable list of approved biocidal active substances.
