EPA proposes refrigerant rule

It's a pretty new action, and interesting only that it's not every day that the EPA makes a big ruling and there isn't immediate pushback from business etc.
Basically US industry is ready to move on from HFCs, saw the handwriting on the wall, and there is an international treaty that is more or less in line with US law. So they're going to get going, and it will be factories in China, North Korea, Africa, India, maybe even Russia that drag their feet.
I do know that there are a lot of compounds in electronics manufacturing that are being reformulated to be washable with either water or isopropyl alchohol. The days of tricholorethane or before that, carbon tetrachloride, are long gone. I am told that old vets from the 1960's had use of some pretty strong (and carcinogenic) solvents, like benzene.
I also know that my old can of Johnson Wax WW2 GI Bore Cleaner smells just like the magic markers from when I was a kid, with some solvent that is probably carcinogenic too LOL.Last edited by togor; 05-03-2021, 01:22.Comment
