Environmentally Friendly Rust, Mill-Scale Remover

December 1, 2015

PPG Industries’ industrial coatings business, Pittsburgh, PA, has introduced Corrokleen 44 rust remover, an application-friendly citric-acid-based gel cleaner that proves effective at removing rust and mill scale, while being safe for users and the environment. Formulated without phosphates and other strong acids, Corro-Kleen 44 features a shear-thinning gel structure for simple spray application, and a low-shear thixotropy that adheres the product to surfaces.

Use the cleaner on rusted or mill-scaled hot-rolled steel or rusted cold-rolled steel to effectively eradicate metallic oxides, heat scale and heattreated stains. Useful for the removal of blush/flash rust from previously blasted surfaces, it also proves ideal for cleaning industrial machinery, hot-rolled steel fabrications, heavy-duty construction equipment, valves and other equipment sensitive to blast media.

CorroKleen 44 rust remover comes in 5-gal. pails and 55-gal. drums, and can be applied with a brush, airless spray nozzle or manual sprayer.
