The reason WD40 evaporates so quickly, is because it's mostly water.

There is no water in WD-40.
WD-40's main ingredients as supplied in aerosol cans, according to U.S. Material Safety Data Sheet information, are:

50% "aliphatic hydrocarbons". ...
<25% petroleum base oil. ...
12–18% low vapor pressure aliphatic hydrocarbon. ...
2–3% carbon dioxide. ...
<10% inert ingredients.
