PPG Industries’ industrial coatings business has introduced CorroKleen 44 rust remover. It is an application-friendly citric-acid-based gel cleaner that PPG claims is more effective at removing rust and mill scale and safer for both users and the environment than traditional grinding, sanding, media blasting or chemical-based solutions. Formulated without phosphates and other strong acids, CorroKleen 44 rust remover features a shear-thinning gel structure for easy spray application and a low-shear thixotropy that adheres the product to surfaces on which it is applied. Designed for convenient, worker-safe and environment-friendly application on rusted or mill-scaled hot-rolled steel or rusted cold-rolled steel, it effectively eradicates metallic oxides, heat scale and heat-treated stains. Useful for the removal of blush/flash rust from previously blasted surfaces, it is recommended for cleaning industrial machinery, hot-rolled steel fabrications, heavy-duty construction equipment, valves, trailer frames and other equipment that is sensitive to blast media. Marie C. Vicéns, product manager, PPG TrueFinish products, said CorroKleen 44 rust remover delivers a unique combination of cost-effectiveness, environmental compatibility and enhanced performance. “Not only is this product less expensive to use than sanding, blasting and harsh chemical treatments, its gel-like consistency also makes the treatment easy to apply to vertical, three-dimensional and hard-to-reach surfaces. Additionally, because its formula is based on natural citric acid, using and disposing of the product is much simpler and safer.” CorroKleen 44 rust remover is available in 5-gallon pails and 55-gallon drums, and it can be applied with a brush, airless spray nozzle or manual sprayer. In most applications, it eliminates heavy oxidation and scale within two to four hours of application. www.ppgtruefinish.com
