Case Study

Extended Life for Coarse Water Filter Screens Pro-biofoul, Anti-foulant



Client

Power Industry, UK.

Application date

2004.

Scope of work

Prepare screens by pressure washing, manual cleaning & scraping, then abrasive blasting to remove marine growth, debris and corrosion deposits. Assess repair work. Apply corrosion protection and Biofoul.

Products

Corroglass 600 Series for repair and re-profiling, with a Polyglass PPA primer coat. Top coat of Biofoul applied for anti-fouling requirements.

Substrate

Steel fabrication.

Coating system

• Grit blast whole structure to ISO 8501-1, cleanliness standard SA 21/2 with minimum surface profile of 50μm. • Apply Polyglass PPA to whole structure as a primer for the Corroglass 600 Series, applied to a min.dft of 1.5mm. • Apply top coat of Biofoul.

Coating credentials

Biofoul is an eco-friendly non-toxic coating. The mechanism by which Biofoul provides anti-fouling properties enables the product to be used in both static and self-polishing environments. The coating is mechanically strong (unlike many self-polishing anti-foulants), has a long life (when used in conjunction with a Corrocoat corrosion system) and is non-toxic. By applying a final coat of Biofoul, the Power Station has eliminated the costly requirement for regular cleaning & maintenance by divers. In addition to this replacing these screens would have cost considerably more than re-profiling and protecting by Corrocoat.
