NA-SUL 420 is an easily emulsifiable rust preventive concentrate ideally suited for the protection of metal parts during storage.



ADVANTAGES:
Effective on steel, galvanized steel and aluminum
Deposits extremely thin hydrophobic films
Films dry very quickly and are easily removed with alkaline cleaners
Emulsions form easily even in cold water
Emulsions that have slightly separated due to prolonged standing can be easily reformed with stirring

Water-Based Cleaners                                                           1.0% - 5.0%

NA-SUL 420 based 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 rusting.

NA-SUL 420 is 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%. This fluid is applied by power spray washer systems to remove the metalworking fluid from newly machined parts. In addition to cleaning, the NA-SUL 420 based fluid leaves a thin, dry film that protects the metal parts during indoor storage.
