Fouling Control System Touts Long Life


AkzoNobel's International brand has introduced a foul-release system for the North American power, water and wastewater segments.

Intersleek 381/425 is a long-life fouling control system designed for use in wet or underwater service applications, according to the company.

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

3-Coat System

When applied with standard spray equipment and used with suitable anticorrosive primers, the three-coat system offers a "highly effective, long-life fouling solution," according to the company.

After a thick-film corrosion-resistant primer, Intersleek 381 can be applied as a second coat. The modified silicone polymer attaches to a non-slick finish, the company says. Intersleek 425 is applied as a third coat. The advanced silicone polymer produces a low-tension, non-stick surface that makes it difficult for biofouling to attach effectively, even at low water currents, according to AkzoNobel.

"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," says Kari Nollsch, the company's North American Water and Wastewater Market Champion.
