The customer needed to remove rust and protect the exteriors of sunflower oil reservoirs. However, mechanical rust removal such as sandblasting and water blasting were restricted in the area. As a result, the customer removed loose rust with a wire brush and pressure washed the surfaces with VpCI®-414 and water. After cleaning, the customer applied CorrVerter® Rust Converter Primer before applying a 2K epoxy middle coat followed by a 2K enamel topcoat. The surface prep problem was solved, and the customer was very satisfied with Cortec’s alternative to sandblasting.
