"non-glycol" additives

MasterP · 09-August-07, 06:24 PM

Does anyone happen to know what "non-glycol" automotive coolants use as their active ingredient?

I'm currently looking at changing my mix from propylene glycol/water/algaecide as I'm getting an acrylic res that has glue joints (and ideally I don't want the glycol attacking them too much)

Thought that the glycol free option may be good (except if it's alcohol based

)

Racing non-glycol coolants are polymer based.

Watter Wetter is DiIsoPropyl Alcohol Ether, TriIsopropyl Alcohol Diether, Sodium Molybdate, Tolyltriazole, PolySiloxane Polymer. Pretty nasty stuff.

IceClear PGX non-glycol antifreeze lists nothing more than complex carbohydrates and water in the MSDS sheet. But since it is a strong oxidizer and the "decomposition product" is oxides of carbon, I'm guessing it's organic based like Dex-Cool. But without the glycol that Dex-Cool uses or any of the added anti-corrosion chemicals.

Awesome!!! Thanks heaps for that
(Geez, them's some nasty ingredients... and I thought that ethylene glycol was bad on its own!!
