v

NPC AF-SIL06 is the new Nanto Paint® high performance anti-friction coating

with hovercraft effect for hulls applications.

Based on an epoxy-siloxane formulation, it incorporates a new anti-corrosion and anti-friction

technology, enhanced by the addition of functionalized nanoparticles. The product is

commercialized and integrated within the Nanto Paint® NPC 8000 series for yacht market.

Nanto Paint® is the unique brand, which combines traditional industrial coatings with the finest cutting-edge

nanotechnology.

The nanotechnology inside Nanto Paint® coatings is provided by Nanto Cleantech, a US based technology company which

owns more than 110 patents worldwide related to its innovative technologies for anticorrosion, fire retardant, antifouling

and anti-stick applications.

Nanto Advantages Sustainable fouling control Nanto Paint® NPC AF-SIL06 is based on an epoxy-siloxane formulation completely biocide-free. This means the product is without toxic components, ensuring our seas and oceans are clean and safe. High reduction of fuel consumption The high performances of the products allow a remarkable energy saving, resulting in less fuel consumption. We share and monitor with our customers the performance results, in order to enhance a long term value proposition. Enhanced drag reduction The nanotechnology inside Nanto Paint® NPC AF-SIL06 improves the performances of the coating enhancing the smoothness effect. Cost saving The product allows low cost maintenance and long servicing life as there is no need of masking and less number of coats. The days at dock are reduced and it is possible to apply on top of old systems in good conditions. Easy to apply

Nanto Paint® NPC AF-SIL06 is easy to apply as a

standard epoxy coating by airless.

Traditional foul-release coatings

Nanto technology for anti-friction

Superhydrophobic surfaces (SHS) have been studied for

their potential for drag and skin friction reduction that

can possibly lead to greater speeds while reducing fuel

consumption.

Due to sophisticated micro-nano tailored hierarchical structure SHS

can form a stable layer of air between the hull's wall and the fluid.

Air-liquid layer reduces the solid-liquid interface and modify the

turbulence boundary layer, with very low drag that enables net drag

reduction.

surfaces with hydrophilic pins for air retention under wa-

ter. Adv, Mater. 22,2325-2328 (2010)

Traditional foul release coatings are based on silicone, which

provides the anti-friction properties. The anti-friction technology

inside Nanto Paint® NPC AF-SIL06 is enhanced by the addition of

nanoparticles (NPs) which ensure surface stability, and at the same

time increase durability.

In particular, nanoclays are used as raw materials for:

• Reinforcement;

• Barrier effect improvement;

• Corrosion resistant increase;

• Antimicrobial and fouling retardant.

The incorporation of NPs can lead to a drag reduction from 5% to

36%. Friction tests have been performed by the Shenkar College of

Tel Aviv. This results in a reduction of fuel consumption and

increase of ship’s speed or decrease of the engine power.
