Intersleek offers solution to smoother hull
The paint manufacturer International Marine has developed a hull coating that does not require the removal of existing coatings prior to the application of the company’s Intersleek system.
Continued research and development, particularly in the area of adhesion mechanics has resulted in the latest innovation to complement the Intersleek range, Intersleek 7180 Linkcoat. Previously, access to the benefits of biocide-free foul release systems for vessels coated with non SPC (self polishing copolymer) antifouling coatings has usually meant full blast cleaning of the underwater hull to remove the existing coatings prior to installation of the Intersleek system.
Intersleek 7180 Linkcoat now allows access to the company’s fluoropolymer based Intersleek 900 and silicone based Intersleek 700 foul release technology without the need and expense of full underwater hull blast cleaning.
Adhesion to and performance over a wide range of existing antifouling surfaces is provided by the specialised dual-cure technology (DCT) utilised in the company’s Linkcoat. An initial fast cure provides excellent drying and barrier properties while a secondary cure employing flexible polymer chemistry enhances system adhesion. Intersleek 7180 Linkcoat also fills in and levels out the rough surface of an existing antifouling to provide the basis for a smooth finish that is almost as good as the Intersleek system being applied to a fully blast cleaned surface. The smooth surface produced, reduces drag, significantly improves vessel efficiency and reduces fuel consumption and associated emissions.
Compared to a full blast and full scheme application on a typical VLCC vertical sides application, savings could be over $450,000, through shorter times in time in drydock and reduced surface preparation and application costs.
