It's got to be the most expensive source of "Simethicone" available... manufactured using pharmaceutical GMP standards by Novartis. However, I suppose you could carry a couple of tablets in your...

The specific gravity of each is close enough that a ratio by either weight or volume will work. Try 4:1 and then add the last bit of solvent slowly, until you get the emulsion consistency that you...

My friend insists on calling it silicone, not silicon... the former is an organic molecule, and latter is an element.

I just had breakfast with a friend who sells chemicals, including various silicone based products. His company anticipates that one day silicones will be declared a risk because of bioaccumulation....

So, cosmicmiami, did you use denatured alcohol or mineral spirits? :confused:

I think you are correct, Knotty, because silicon we use for waterproofing is really a silicon polymer called Polydimethylsiloxane (PDMS) or dimenthicone, an inert, non toxic, non flammable substance...

That's because denatured alcohol (ethanol) and mineral spirits (petroleum distillates) are totally different things.

IX has a different problem. You get 100% un-diulted Insultex at a reasonable price per yard, but the minimum order quantity is huge.

$40 per gallon for something that is 70% to 94% water, and covers 150 square feet!

I think I read it right...

:eek:

Great report, Rain Man!

Thanks!
:thumbup:

It must be delivered with a solvent, though. I'm just curious... it doesn't really matter. Us chemical types sometimes care more about the solvent than the solvate!

I don't know how I missed this, but I just learned that in recent years, silnylon makers had to stop using whatever solvent they were using... now they use polyurethane as part of the solvent for...

Deadline is man's best friend... when do we lay the cloth, so to speak?

Interesting idea!
Brand name?
Source?
Link?
:confused:

Pressure will not affect the liquid phase. If you immerse the fabric in a silicon solution, that liquid and it's contents will not be affected by the pressure of the vapor phase above it.

That is an excellent idea!
