Chemical Resistance
4 Chemical Resistance
4.1 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%
Citricacid 10% Phosphoric a cid 10%
Diesel Sea water
Distilled w ater Sodium chloride 2%
Edibleoil Sodiumchloride 20%
Fuel oil Sulphuric acid 20%
Hydrogen peroxide 3% Tap water
The powder paint shows limited resistance to the f
ollowing chemicals at room
temperature:
Butanol Nitric acid 3%
Hydrochloric acid 5% Nitric acid 10%
Isopropyl alcohol Phosp horic acid 43%
Na-hypochlorite 10% Turpentine
Note:
If exposure to any of the above chemicals is demanded, it is recommended to fi rst test
the chemical in a hidden spot of the metal casing.
