De watering oil

Promtech Chemicals offers Aquanil DWO, a petroleum solvent based de watering oil, which also acts as excellent rust preventive, by deposition of a thin film of rust preventive on the treated components. Aquanil DWO is light brown to amber, slight viscous, volatile, non toxic non corrosive liquid and has a specific gravity of 0.82 ?0 02. Its oil absorption value is nearly 30 to 35%. Water displacement is excellent. It is non-drying and is applied by dipping/spray. The resultant film thickness is 0.5 to 1 micron. It passes 72 hours salt spray test. It has coverage of 200 250 sq.ft per litre by brushing. It can be removed by swabbing with thinners. It can be used for fabricated ferrous and non-ferrous metal components, and on all pickled, phosphated, blackodised and electroplated components preferably by dipping method. Especially it is recommended for metals pickled in hydrochloric acid baths (which are prone to rusting). The treated components now acquire 2 3 months of indoor rust protection.
