Commonly in the Marine industry, cavitation occurs on rudders, vanes in pumps and on propulsion systems. Cavitation damage can lead to severe erosion-corrosion problems and render equipment useless if left untreated. Millions are spent every year on replacing equipment damaged by cavitation which is not only expensive and time consuming, but the like for like replacement solution will not resolve the problem.
Damage caused by cavitation can be repaired without the need for hot work with a Belzona paste grade composite material. After repair of existing damage, a combination of ceramic epoxy coatings and resilient polyurethane elastomers, can be utilized to provide long-lasting corrosion and cavitation protection.
Our ceramic coatings have a proven track record of increasing efficiency in fluid flow situations, as well as stopping corrosion and significantly reducing the effects of erosion. Belzona polyurethane coatings are designed to absorb and dissipate the cavitation energy, thus reducing its effects.

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:
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.

Designed to safely remove scale and unsightly hard water stains, the Assurety Organic Hardwater – Lime - Scale Remover has been engineered to dissolve the chemical bonds in Calcium Carbonate (CaCO3), the backbone of hard water, scale, and other troublesome deposits.
The Assurety Organic Hardwater – Lime - Scale Remover leaves surfaces such as paint, metal, ceramic, and glass untouched and unclouded. The Assurety Organic Hardwater – Lime - Scale Remover is not only more effective, but much safer when compared to traditional Mineral/Inorganic Acidic products. Safer for the user, equipment, and the environment the Assurety Organic Hardwater – Lime - Scale Remover does not contain any: Hydrochloric, Phosphoric, Muriatic, or Citric acids.
An efficient, cost-effective, safer solution for the removal of scale, marine growth, barnacles, zebra mussels, calcium, and rust from marine heat transfer equipment, engine water jackets, hulls, props and ancillary equipment. Effective on boats, ships, drilling rigs, pleasure crafts and other marine environments.
