28Nitto Denko Group Report 2013Research and DevelopmentThe Nitto Denko Group combines its core technologies – adhesion, coating, polymer function control and polymer analysis and evaluation – with new technologies to carry out research and development primarily focused around our growth strategy of “Green, Clean and Fine”.Environmentally Friendly MARINGLIDE™ Film Protects Ship HullsIf you look at the hulls of ships and boats, you will often see many marine organisms, such as barnacles. How did they get there? The larvae of these organisms were oating in the ocean and attached themselves to the hull of the vessel as it passed by. Once they have attached themselves, then they rapidly grow in size and not only look bad, but also increase water resistance, which in turn has a major impact on fuel consumption and speed. Because they become attached so rmly, in some cases the hull is damaged when they are scraped off. Up until now, antifouling paint has been the main method of preventing barnacles from attaching themselves to the hulls of vessels. However, it is feared that the substances contained in such paints to repel barnacles may have a detrimental effect on the environment. Nitto Denko has therefore developed MARINGLIDE™, the industry’s rst adhesive lm that repels barnacles. The main characteristics of this lm are shown below.1. Easy MaintenanceWhen MARINGLIDE™ is applied to the hull of a vessel, a very small amount of oil is released from the surface of the lm, which makes it difcult for barnacle larvae to attach themselves to the hull. Even if the lm becomes fouled, it can be easily cleaned by water blasting and remains effective for about three years, after which it can be easily peeled off and replaced. It is easy to work with, does not damage the hulls of vessels and reduces vessel maintenance costs.2. Reduced Water ResistanceAs the surface of MARINGLIDE™ is smooth and does not have the rough nish of paint, frictional resistance is extremely low. This, combined with the fact that barnacles cannot attach themselves to the hull, means that water resistance can be reduced by about 10% or more. It is generally said that if frictional resistance can be reduced by 10%, then this will result in an improvement in fuel efciency of 7% to 8% and also potentially result in an increase in speed. There was a great deal of interest regarding MARINGLIDE™ among boat owners at the Japan International Boat Show held in March 2013. The product is expected to go in sale in 2014 after further testing and improvement.
