- Product Uses
- NA-SUL®437 is a unique water soluble rust preventive concentrate. It can be cut back in either cold or warm water. NA-SUL® 437also shows excellent hard water tolerance. It exhibits exceptional storage stability both as the concentrate and in water solutions.
- Unlike most water soluble rust preventive additives, NA-SUL® 437 deposits a thin film upon metal parts that becomes hydrophobic during drying. This enables parts to resist rusting for extended periods, even in the 100% humidity environment of the Humidity Cabinet (ASTM D 1748) test. The thin protective film can easily be removed with alkaline cleaners. Water solutions of NA-SUL® 437 are ideal for dip application of metal parts for protection during indoor storage. Wet parts may be dipped in NA-SUL® 437 solutions replacing the need for solvent based dewatering fluids.
- To achieve foam control in NA-SUL® 437 solutions, it is recommended to use Foamban® MS-525 (Munzing, Inc. Bloomfield, NJ.). Add the antifoam at a concentration of 0.1% of the NA-SUL® 437 concentration in the solution.
- A typical formulation based on 1000 g could be: 950 g water, 49.95 g NA-SUL® 437 and 0.05 g Foamban MS-525.
