well, you all lured me into finally checking out and readin up on the "infamous" wd-40,
it's formulation, suggested uses, function, ect.
here's what i found, on the wd-40 website, and wikipedia....it can't be wrong, i read it on the internet, LOL
wd-40 Function:
The long-term active ingredient is a non-
volatile, viscous oil which remains on the
surface, providing lubrication and protection
from moisture, This is diluted with a volatile
hydrocarbon to give a low viscosity fluid
which can be sprayed and thus penetrate
crevices.
The volatile hydrocarbon then
evaporates, leaving the oil behind. A
propellant (originally a low-molecular weight
hydrocarbon, now carbon dioxide) provides gas
pressure in the can to force the liquid
through the spray nozzle, then evaporates
away.
These properties make the product useful in
both home and commercial fields; removing dirt
and residue, and extricating stuck screws and
bolts are common usages, and it also loosens
stubborn zippers.
The product also may be
useful in displacing moisture, as this is its
original purpose and design intent.
Due to its lightness (i.e., low viscosity),
WD-40 is not always the preferred oil for
certain applications. Applications that
require higher viscosity oils may use motor
oils, while those requiring a mid-range oil
could use honing oil.
Formulation:
WD-40's formula is a trade secret. The product was not patented in 1953 to avoid disclosing the details of its composition; the window of opportunity for patenting the product has long since closed.
WD-40's main ingredients as supplied in aerosol cans, according to U.S. Material Safety Data Sheet information, are:
50% "aliphatic hydrocarbons". The manufacturer's website specifically claims that this fraction in the current formulation cannot be accurately referred to as Stoddard solvent, a similar mixture of hydrocarbons.[8]
25% petroleum base oil, presumably a mineral oil or light lubricating oil.
12-18% low vapor pressure aliphatic hydrocarbon, to reduce the viscosity for use in aerosols. This fraction evaporates during application.
2-3% carbon dioxide, presumably as a propellant, is now used instead of liquefied petroleum gas to reduce WD-40's considerable flammability.
10% inert ingredients.
not sure what anyone else reads, but i most certainly see it listed as a light, and even a strong lubricant !
link to "2000 uses for wd-40" someone care to count how many times it says "lubricant "
