AkzoNobel’s International® brand of protective coatings, linings, and fire protection products, is pleased to introduce Intersleek® 381/425, an advanced high technology long life fouling control system, into the North American power and water and wastewater segment.

Wet and Underwater Applications
Designed specifically for use in wet or underwater service applications, Intersleek® 381/425 helps significantly reduce maintenance and cleaning costs associated with fouling control without the harmful environmental impact of biocides. When applied with standard spray equipment and used in conjunction with suitable anticorrosive primers, the thermally and chemically resistant three coat system offers a highly effective, long-life fouling solution:

• First Coat:: Intershield® 300HS – International®’s thick-film corrosion-resistant primer. 
• Second Coat:    Intersleek® 381 – A modified silicone polymer that attaches to a non-slick finish to provide the first level of antifouling defense.
• Third Coat: Intersleek® 425 – An advanced silicone polymer that produces a low tension, non-stick surface. The coatings’ low-energy surface tension makes it difficult for biofouling to effectively attach, even at low water currents. 

Typical areas of antifouling application include: penstocks and trash screens, sewage clarifier tanks, fresh water intakes, tunnels and fresh water channels.

The Money Saving Solution
Karl Nollsch, AkzoNobel’s North American Water and Wastewater Market Champion, explains, “Industries that rely on equipment operating in wet environments are continuously faced with the problem of fouling growth which can affect the performance and safety of equipment. This problem can be particularly costly when the equipment operates underwater and there is limited access for vital maintenance and repair. Unlike biocide-containing fouling control systems, Intersleek® does not have to be replenished and is considered to have a lifetime equal to most undamaged, underwater structures. It is by far the most cost effective fouling control option for static wet structures.”  

Protect Steel and Concrete in Fresh and Salt Water
The financial impact of plant shut downs, reduced efficiency, capital replacement and maintenance due to biofouling in power, water, and industrial facilities, is estimated at millions of dollars. With more than 25 years of proven experience in the global marine, petrochemical, power and water and wastewater industries, the Intersleek® 381/425 foul release coating system is North America’s preferred choice for protecting steel and concrete substrates from micro and macro fouling in both fresh and salt water environments.
