A marine hull coating is a remedy for the corrosive effects that fresh, salt, or brackish water have on machinery and other assets. Surfaces slowly deteriorate over time due to electrochemical corrosion caused by moisture, air, and minerals like salt.
Between the water and the substrate, the marine protective coatings act as a barrier to shield it from harm. They are typically used on ships, tankers, and other watercraft, but they are also used on structures on offshore oil rigs, such as propellers and buoys.
For instance, there was severe corrosion on the tugboat of a refinery. After 24 months, the old hull covering had 80% of its bond broken. The hull plates had such severe pitting and corrosion that abrasive blasting breached them in certain places. The tugboat’s hull was coated with the corrosion-resistant coating by the Refinery using a single-component airless spray.
The hull shape is the one parameter that cannot be lost during vessel operation, so this is where attention must be directed. Just remember that a change in roughness of between 10 and 20 microns when the vessel is in operation may cause the overall hull resistance to rise by 1%.
Global marine hull coatings market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Nippon Paint Marine, a market pioneer in high-tech hull coatings, has allegedly developed the first biocide-free, low-friction self-polishing copolymer (SPC) antifouling technology in the world.
The Aquaterras product is a brand-new kind of marine coating that was created without the use of silicone or biocidal substances.
“Traditionally, antifouling paints for ships have incorporated some type of biocide, such as copper, tributyltin, or co-biocides. However, national and international laws, such as the EU’s BPR, strictly regulate the use of biocides nowadays.
Additionally, even while there are no current plans to further control the use of approved biocides, we cannot completely rule out the potential that regulations for copper in antifouling will come into effect soon.
The method uses an enhanced antifouling mechanism based on the non-thrombogenic polymers utilised in the manufacture of artificial blood vessels and hearts in the medical field.
In order to prevent blood clots, the medicinal polymeric material was made so that no biological substances or life could stick to its surface (thrombosis).
The new hydrolysis polymer reaction created by Nippon Paint can continually self-polish by using the technology used in maritime pants. It also makes sure that Aquaterras provides long-term antifouling performance by exposing active micro-domain structures to seawater.
