I am think I am forced to conclude that the meanings of ‘propose’ do not overlap with any of the meanings of ‘ban’
Proposing is one thing, doing is another …

I pull my collar high and slowly step toward the backdoor

We are just bored while waiting for the paint to dry so we practice some friendly infighting :wink:

There is no need for MEK or any of the other harmful products when ethyl acetate does the needed
work safer, cheaper and more efficiently :smiley:

There’s further information below, but let’s focus instead on relevant facts:

  • The ban only applied to MeCl in paint strippers, thus it would not have caused the removal of Tenax 7r - an adhesive - from the market. Mention of that ban is irrelevant.

  • MeCl is still available for sale in the US:

    mecl
    mecl1605×784 75.4 KB

  • Tenax 7r was difficult to find for a decade prior to the non-applicable ban in question.

If Tenax 7r is gone it is because the manufacturer decided it wasn’t worth making, not because it or its main constituent have been banned. I’ll bet it’s been awhile since any of us have bought a new tube of Testors cement but it’s because we’ve found something better, not because of government action.

The proposal to ban MeCl in paint strippers was made on 19 January, 2017, which you’ll recognize was less than 24 hours before the end of the Obama administration. “proposals”, of course, have no effect or validity in regulation.

The Trump administration conducted the required and usual studies, risk analysis, and hearings concerning the use of methylene chloride for consumer paint and coating removal. The Trump administration then published the rule (which was the ban on use in paint strippers) on 27 March, 2019, with an effective date of 22 November, 2019, almost three year’s into President Trump’s term.

So, except for the few hours in President Obama’s administration waiting for the ink on the official paperwork to dry, the entire legal effort to put the ban - on MeCl in paint strippers - in effect came during President Trump’s administration. Thus it seems, well, ignorant, to effectively blame Obama for proposing something that Trump agreed was worth doing.

So do I. I use Testors liquid for most things, Tamiya Extra Thin for most others, Tamiya “orange cap” for a few more, an Testors “black wedge” for one or two applications.

The difference between the available adhesives of a given type is quite small and a rigorous scientific experiment probably would not show a significant difference in performance.

Blame? I didn’t say blame. Yet again, your over reaching, attaching an emotional statement.

Credit, blame, responsibility whatever you’d like to label it, Obama inked & Trump followed through.

I,m curious about this ethyl acetate, use like any other cement,and where can it be found

29

It is a solvent, occurs naturally in some fruit (very low concentrations).
One of the ingredients in some acetone free nail polish removers, can be used for model building in an emergency, must not contain any oils or fats.
Used in chemical industries, medical laboratories, paint thinner (ask around in paint shops)

https://www.americanchemicalsuppliers.com/list/search?search=ethyl+acetate

I bought 5 litres from a paint shop which is specialised in restorations so they need to dilute
old paint types.
The problem is to find a smallish packaging, a gallon or two is a bit much but if you split it with others it might be reasonable
Laboratory grade is unnecessarily expensive for no extra benefit, aim for paint thinner quality.

It is a solvent which softens the chemical bonds between the styrene molecules in polystyrene, when it evaporates the styrene molecules bind to each other again.
The joint is more or less, it’s not a perfect process, turned into solid plastic.
This means that it isn’t a glue which holds two surfaces together, it turns the two adjacent parts into one part.

After reading this discussion decided to check on my " stash "of Tenax , out of 12 “sealed” bottles I was able to consolidate to one 95 % full bottle. :unamused: At least got a lot of mixing bottles. Is Weld On 3 same stuff ?
Now I mostly use Tamiya and Revell cements. Also have a few bottles of Faller Cement.
Hope all of you guys are well and have a great weekend ! Cheers, Tony

Tenex is gone but Micromark sells a product called “Same Stuff” which is the exact same as Tenex.
