Just a heads up on a new EPA law in the US that prohibits the sale of methylene chloride to individuals May 5, 2025. It’s the Toxic Substances Control Act and after that date you need to be a business I guess to purchase it.
It’s nasty stuff, linked to six kinds of bad cancers and a host of other heath effects, and it’s probably time for it to go. But for those who might use it and need to use it…
Do you think we are using it, whatever it is?
If you are using the best PLA glue ever, SCIGRIP 16, you are.
I’m good then, I never use glue.
I have no idea. The group here is pretty diverse and while some are in business, I don’t know who is or isn’t and just posted in case it was important to anyone.
It’s nasty stuff and I don’t use it, but the resin printer guys maybe or maybe others use it for plastic gluing and other things. It is a very powerful solvent.
I wonder if that means they are going to stop decaffeinating coffee with it now.
I think most coffee is decaffeinated with supercritical carbon dioxide now. It used to be done with methylene chloride on the hopes that it would all leave before the coffee was consumed. Some may still use it though.
Coffee done with CO2 is usually marked as “naturally decaffeinated”. I’m not a decaffeinated drinker but I would only recommend coffee decaffeinated using CO2.
