freeze 12 is like 90% 194A. We normally just dump 194A on top of the R12 at work. It isn't recomended, but we have yet to have one come back complaining.
I have been told (with no documentation or other proof) that Du Pont essentually created the scare to keep ppl buying there product (freeze12) once there original prduct was outlawed (R12).
Again...only what I have heard through the industry.
And with the other things I have heard about DuPont, I believe it myself.
