Phosphoric acid 4%
Citric acid 10%
Phosphoric acid 10%
Diesel
Sea water
Distilled water
Sodium chloride 2%
Edible oil
Sodium chloride 20%
Fuel oil
Euphoric acid 20%
Hydrogen peroxide 3%
Tap water
The powder paint shows limited resistance to the following chemicals at room temperature:
Chemicals
Butanol
Nitric acid 3%
Hydrochloric acid 5%
Nitric acid 10%
Isopropyl alcohol
Phosphoric acid 43%
Na-hypochlorite 10%
Turpentine
Note:
If exposure to any of the above chemicals is demanded, it is recommended to first test the
chemical on an invisible spot of the metal casing.
