NA-SUL 420 water emulsions are ideal for dip application of metal parts for rust and corrosion protection during indoor storage. Emulsions based on NA-SUL 420 deposit thin, hydrophobic protective films ranging from dry to slightly oily depending on the concentration. This product provides excellent humidity protection with some salt fog resistance at higher concentrations. The protective films dry quickly, yet are removable with alkaline detergent. Emulsions based on NA-SUL 420 effectively protect steel, galvanized steel and aluminum from corrosion.

NA-SUL 420 can be successfully used to protect automotive parts as a key ingredient in a water-based cleaner/rust preventive fluid at a treat level of 2.0% to 3.0%. These fluids can be applied by power spray washer systems to remove metalworking fluid from newly machined parts. In addition to cleaning, NA-SUL 420 based fluids leaves a thin, dry film that protects metal parts during indoor storage.
