ENTEK-NR-40 (5-USgl-Pail)

ENTEK NR-40 Mild Cleaner & Temporary Rust Inhibitor for Iron and Steel

Overview

ENTEK NR-40 is a non-flammable, alkaline liquid cleaner and temporary rust inhibitor formulated for cleaning, degreasing and protecting iron and steel components. Diluted with water, it removes oils and contaminants while leaving a thin, virtually invisible corrosion-inhibiting film that protects metal surfaces between manufacturing or finishing operations. ENTEK NR-40 is particularly suited to complex components that cannot be thoroughly rinsed with water, making it ideal for aerospace, engineering and industrial maintenance applications.
