International Paint Ltd. introduced Intershield®803Plus, a cargo-hold coating specifically designed to address the issue of impact damage from the loading of dry bulk cargoes.
The coating is reported to offer superior impact and abrasion resistance, good corrosion protection, VOC compliance with 75% volume solids, fast drying times, and year-round workability. The cured coating is characterized by a smooth surface for easy cleaning, is certified for the transport of grain, and is FDA compliant, said Rob Taylor, International Paint market manager of bulk carriers.
Cargo holds of bulk carriers are subject to severe operating environments that require a high degree of coating protection to ensure the structural integrity of the holds, in addition to continued vessel profitability and safe operation, the company said in announcing the product introduction.
The company added that growing exports of hard, abrasive cargos such as coal and iron ore have increased the potential for significant coating damage during loading. The potential is particularly prevalent during the loading of coal by high-speed belt conveyor systems, leading to the phenomenon of “shooting” damage to cargo holds. This can occur when loaders project coal at right angles to the bulkhead; the impact can fracture and detach coatings, leading to loss of steel protection and subsequent corrosion. These areas of damage often are located high on the bulkhead and can be difficult to repair in service.
The company said the product has been designed using a new test method capable of replicating the in-service conditions in coal and iron-ore carriers. The test results are reported to have confirmed the product’s performance capabilities in such environments.
Taylor described the product as “our toughest ever cargo-hold coating.”
