No one has stated what the product is?????


I did. Check my post above.

Freeze 12 is 20% HCFC-142b (hydrochlorofluorocarbon) and 80% HFC-134a (hydrofluorocarbon). It does not contain any propane, butane, or isobutane. It is on the EPA list of approved R12 substitutes.

It appears that the EPA is banning 142b, but it can be used to support existing refrigeration systems. See link.

The EPA also states that there is no "drop in" refrigerant substitute. This means that you cannot add a freon substitute (such as Freeze 12) on top of the existing R-12 in the system. You must remove (recover) the existing R-12 from the system so that when the system is filled with the freon substitute, it (the system) will not have a mix of R-12 and the substitute freon.
