Silicone.

Just what is in your imagination about this stuff?

It sure beats oil based lubricants such as WD-40 by miles. Experience alone, living in a desert w/sand/dirt for 20+ yrs. indicates otherwise.

It's a type of oil, you know, just not a mineral, animal, or vegetable oil.
Certainly it attracts dirt.

Really? An OIL? Then how do you describe/ascribe to the following? I'm not aware of ANY OIL that will sustain 5905 degrees F to a boil point!

Silicon

Atomic Number: 14


Atomic Weight: 28.0855


Melting Point: 1687 K (1414°C or 2577°F)


Boiling Point: 3538 K (3265°C or 5909°F)


Density: 2.3296 grams per cubic centimeter


Phase at Room Temperatu Solid


Element Classification: Semi-metal






History and Uses:

Silicon was discovered by Jöns Jacob Berzelius, a Swedish chemist, in 1824 by heating chips of potassium in a silica container and then carefully washing away the residual by-products. Silicon is the seventh most abundant element in the universe and the second most abundant element in the earth's crust. Today, silicon is produced by heating sand (SiO2) with carbon to temperatures approaching 2200°C.

Two allotropes of silicon exist at room temperatu amorphous and crystalline. Amorphous appears as a brown powder while crystalline silicon has a metallic luster and a grayish color. Single crystals of crystalline silicon can be grown with a process known as the Czochralski process. These crystals, when doped with elements such as boron, gallium, germanium, phosphorus or arsenic, are used in the manufacture of solid-state electronic devices, such as transistors, solar cells, rectifiers and microchips.

Silicon dioxide (SiO2), silicon's most common compound, is the most abundant compound in the earth's crust. It commonly takes the form of ordinary sand, but also exists as quartz, rock crystal, amethyst, agate, flint, jasper and opal. Silicon dioxide is extensively used in the manufacture of glass and bricks. Silica gel, a colloidal form of silicon dioxide, easily absorbs moisture and is used as a desiccant.

Silicon forms other useful compounds. Silicon carbide (SiC) is nearly as hard as diamond and is used as an abrasive. Sodium silicate (Na2SiO3), also known as water glass, is used in the production of soaps, adhesives and as an egg preservative. Silicon tetrachloride (SiCl4) is used to create smoke screens. Silicon is also an important ingredient in silicone, a class of material that is used for such things as lubricants, polishing agents, electrical insulators and medical implants.

And if you don't have any residue of it, then
what exactly is the point?

Really? and the facts/data are? Residue is the **** you don't need after applying a product for a particular need. Weird how it seems to work here in this blowing dirt/sand country.

Many "silicone" sprays are 99 percent mineral spirits and other hydrocarbon
stuff with a whiff of actual silicone oil. That's why it doesn't attract
dirt or leave a residue: it just evaporates after making you feel better.

Well that's certainly strange, even CRC doesn't list their silicone spray @ 99% mineral spirits & other hydrocarbon
stuff. http://www.crcind.com.au/catalogue.nsf/(MSDS)/3055%20808%20Silicone%202007/$FILE/MSDS.pdf

It certainly seems strange that you are seemingly opposed to using silicone spray as a lubricant for a seemingly innocent purpose of lubricating a sliding patio door.

Much less as leading off with mis-information.............just my 2 cents worth...............
