16 is junk and even if this new regulation effected me, I still would not use 16.

It doesn't say anything about weld on #16. If 3 and 4 are discontinued just use 16.

It has its place. 16 certainly is not easy to use on small pieces. And it does not wick at all.

16 isn't supposed to wick. it's a junk filler that should never be used for water applications.

Is trichloroethane less regulated than trichloroethylene? If so it seems like they can quickly revamp their product for consumers. We use them both as solvents pretty interchangeably.

AlanM · Oct 11, 2016

Sorry, got that backwards. My officemate reminded me it was the ethane that we were phasing out in favor of the ethylene because of ozone concerns, not toxicity. They work about the same and are similarly toxic.

Talked to the scigrip rep on the phone. I'll have an update later. possibly not good at all.

So apparently scigrip 3 and 4 are supposed to be pulled from online sales. Physical retail sales are OK per the guidelines on the press release.

The changes per the release are somewhat temporary pending further discussion between ips and the epa. worst case scenario, no more scigrip 3 and 4.

If anyone knows of online retailers who are still selling scigrip 3/4, or retail locations selling to consumers, please pm me the names and locations. Thanks.

Yeah I called the guy too, he must be getting inundated, he called back and left me a message, I returned it, no return though.

This is a bummer. Are there any viable alternatives?

Fortunately, TCE is not required at all for acrylic bonding. So straight Methylene Chloride works just fine - and that's not going to get banned, it's an industrial solvent and is in many (thousands of) cleaning products.

Good thing I live by the main office of eplastics (ridout). They sell to commercial entities as well so there is no way in hell they will stop selling it.

Now you need a business account to buy it on amazon.

I'm glad Amazon did that.

Turbo's Aquatics · Oct 14, 2016

Pretty much. Chloroform works too actually.

So...I just bought some Weld-on 3 to repair a couple of baffle seams that look a little separated. IF this doesn't come for some reason, what should I look for as a replacement product? I will post a thread with pics before I start the process, but am trying to get the materials coming.
