Cleaner, degreaser imparts corrosion protection

November 5, 2012

Cortec® offers VpCI®-414 cleaner and degreaser, a heavy-duty, temporary coating and wax remover for metal and painted surfaces. This nontoxic, nonflammable, water-soluble, and biodegradable concentrate removes dirt, oils, and greases. As a viscous liquid, it is suitable for underhanging and vertical applications.

The product provides multimetal corrosion protection even after parts have been cleaned, for up to 48 hours. An immersion test showed that the cleaner provides corrosion protection on both carbon steel and cast aluminum panels at 10 percent concentration. A flash corrosion test showed 5 and 10 percent concentrations to be effective for preventing corrosion on carbon steel panels and improved corrosion protection on cast aluminum.

The product does not affect painted surfaces and remains active even if left to dry. It is mostly used at room temperature but can be used in a heated bath for heavy hydrocarbons.
