Product Description


AR22 is a neutral rust inhibitor and light duty cleaner. AR22 is ideal when it is essential to prevent re-rusting without leaving a visible or interfering film. 

AR22 is suitable for use in soak and spray wash operations. AR22 has a wide range of applications including:- final rinse after phosphate operations, as a light duty cleaner for ferrous and non ferrous metals or used in conjunction with a heavier duty cleaner as a rust inhibitor. AR22 is a complex blend of amines and organic acids and will give good rust protection for several days under good internal storage conditions.


Make up concentrations of AR22 vary between 1% - 2% by volume, however optimum concentrations should be determined by trial.
