Sodium Dinonylnaphthalene Sulfonate (T705G)
Chemical Composition: Sodium dinonylnaphthalene sulfonate in light mineral oil
General Description:
T705G is a water-soluble rust inhibitor suitable for use in aqueous metalworking fluids, corrosion protection coatings, and other water-based systems. It provides excellent protection against corrosion for ferrous metals and is particularly effective in preventing flash rusting during metal processing. The sodium-based formulation is environmentally friendly and compatible with most additives used in water-based systems.
