5. Chemical Resistance
5.1. Metal Casing
The frame and casing material is powder-coated aluminum. This powder paint withstands exposure to
the following chemicals without visible change:
Acetic acid 10% Phosphoric acid 4%
Citric acid 10% Phosphoric acid 10%
Diesel Sea water
Distilled water Sodium chloride 2%
Edible oil Sodium chloride 20%
Fuel oil Sulphuric acid 20%
Hydrogen peroxide 3% Tap water
The powder paint shows limited resistance to the following chemicals at room temperature:
Butanol Nitric acid 3%
Hydrochloric acid 5% Nitric acid 10%
Isopropyl alcohol Phosphoric acid 43%
Sodiumhypochlorite 10% Turpentine
NOTE
If exposure to any of the above chemicals is demanded, it is recommended to first
test the chemical in a hidden spot of the metal casing.
The powder paint shows little or no resistance to the following chemicals at room temperature:
Acetic acid, conc. Methyl-ethyl ketone Toluene
Acetone Nitric acid 30% Trichlorethylene
Ammonia 5% Phenol Xylene
Ammonia, conc. Sodium hydroxide 5% 97 octane unleaded petrol
Ethyl acetate Sodium hydroxide 30% 98 octane leaded petrol
