30% Pure Tetra...
« on: May 20, 2004, 04:06:00 AM »
Swik recently purchaced some spray-on brake cleaner, which sais 'contains 315g/kg tetrachloroethylene.'

It does not list what the rest is.

Is there any reason why this couldn't bee used for a tetra wash?

The bottle says 30%?  Most are 100% tce, but SWIM has came across ones that contain toluene and DCM along with it.  Those are usually cheaper than the pure tce, and work fine for most purposes (SWIM has used it before without probs).  What does the spray smell like (besides the tce of course)?  Does it have an underlying lighter fluid kinda smell? Or is it more of a gasolene smell (the lighter fluid smells point to naptha's in the mix, the gas smell would be toluene/xylenes and shit)?  You could always do a google search on it.  Just type in the brand name (like John Does Brake Cleaner for example) and type MSDS after it.  You may have to do a little digging but I'm sure there is an MSDS on the product that'll give hint to what's in it.  Other than that, get a new bottle, a brand that says tce and nothing else.  When in doubt, throw it out!

amalgum mentioned the flammable brake cleaner.
This can be used in certain extraction procedures based on the IDEA Method forumaltion.
Instead of using the Acetone, ISO, and Denatured Alky and Tetra, Ibee has used a 50% Flam Brake cleaner 50% non-flam brake cleaner. This mix was used as an initial pillmass wash. It won't however deal with Orange gaaks and it won't phase eudragit formulations.
In other words...this mix may serve some useful purpose against the lesser gaaks once the more aggressive polymers are removed.

The 100% Tetra lists one other ingredient....Carbon Dioxide(CO2) as the propellant.

The 30% tetra will prove to be ineffective for the purposes here.

A note on the newer gaaks.
They like to hide and will remain invisible throughout most extraction processes.
The data on the Eudragit hints at some solvents and certain pH that these gaaks will precipitate into solids in solution.
This is what bees need to shoot for in order to expose these gaak and subsequently remove them.
