Composites and Coatings for the Marine Industry

More industries

Belzona's comprehensive range of rapid and cold-curing marine coatings and metal repair composites has been used by the marine industry for over 60 years. Our products are specifically designed to withstand harsh offshore conditions and have exceptional resistance against erosion and corrosion.

Providing metal repair composites to shipyards around the world, long-term protection is proven by years of successful experience with ships and offshore structures. Manufactured according to the ISO 9001 quality management systems, Belzona materials are approved by classification societies from all around the world including:

Lloyd's Register
American Bureau of Shipping
Bureau Veritas
RINA Services
DNV GL
China Classification Society
Germanischer Lloyd
Korean Register of Shipping
Russian Maritime Register of Shipping

In addition, our products have received acknowledgements from the U.S. Navy and the U.K. Ministry of Defence.

Marine equipment commonly suffers from cavitation, impingement and entrainment. These erosive forces can quickly destroy conventional coatings and lead to corrosion. Belzona provides long-term solutions to eliminate corrosion and reduce the effects of erosion.

Rudder repair and protection

Rudders suffering from erosion and corrosion are repaired and improved using Belzona’s metal rebuilding composites and epoxy coatings. With insulating properties our erosion resistant products will stop corrosion and limit the effect of the erosive forces. Cavitation is combatted with a coating system combining Belzona 1341 (Supermetalglide) and Belzona 2141 (ACR-Fluid Elastomer).

Marine propulsion system protection and rebuilding

The marine propulsion systems vary depending on the type of vessel, but they all suffer from cavitation problems. Belzona offer metal rebuilding and resurfacing products to reclaim lost substrate. Protect kort nozzles, jet tubes, and propellers from future attack with erosion, corrosion and cavitation resistant materials.

Shaft in-situ repair

Shafts operate under high mechanical forces and this can often lead to damage and wear. With Belzona’s metal rebuilding materials shafts can be repaired in situ with minimal downtime. Our durable, corrosion preventative coatings protect tail shafts from erosive and corrosive effects.

Engine repair

Marine engines commonly suffer from cracked casings and cooling problems. Cavitation and corrosion occurs heavily around the cylinder blocks and liners. These problems can be resolved with our high temperature repair composites and coatings which reclaim and protect damaged areas, extending the engine life.

Shimming and chocking

Precise alignment and anchorage of heavy ship propulsion systems, auxiliary machinery and other heavy equipment can be achieved using the chocking, backing and levelling compound Belzona 7111 (Marine Grade). This pourable material resists pressure, impact and vibrations, providing a reliable foundation for heavy machinery and equipment in the marine environment.

Repair and sealing of rubber components

Rubber equipment common in the marine industry such as fenders, buoys, bellows and hoses are prone to in-service deterioration, where even minor rips and tears can lead to equipment being decommissioned. Belzona Elastomers are cold-applied flexible polyurethanes, which can return equipment into serviceable conditions with reduced downtime and for a fraction of the cost.

At sea repairs

Ideal for use offshore, Belzona fast-curing and extended working life epoxy composites are engineered specifically for in-situ application to wet, oil contaminated and underwater surfaces. Belzona 1212 provides a safe and simple repair solution to unplanned maintenance needs at sea for equipment such as pipes, engines, shafts and hydraulic rams.

Storage tank repair and protection

With potable water approvals and high chemical resistance, Belzona can solve most storage tank problems, ranging from emergency leaks on wet and oily surfaces to chemical attack and corrosion damage.
