Before they stopped producing Tenax 7r I bought a "case" of about a dozen bottles at a train show. I figured it was a good investment at the time, and we all know how good a product it is (was). The whole box of bottles has been sitting in my supplies for a while, and about 2 weeks ago I needed to get some out. To my surprise, almost every bottle is now only about 1/3 full! The container I had the bottles in had a very strong odor of Tenax when I opened it, but there was no evidence anything had spilled. It looks like Tenax must have the ability to evaporate through the lids over time. I know it is very volatile and I've had bottles completely evaporate over a weekend if I leave them open on the workbench.
Oh well...

I had that issue with Tenax for years, I swear there wasn't anything that would stop that stuff from evaporating.

Yep. The last bottle I bought cost me over $10 and evaporated in its entirety before I had a chance even to use a single drop. Now I use ACC or Weldbond as they are more versatile and longer-lasting.

Tenax sure does evaporate quickly. I had a similar experience with buying up bottles before they were no longer available only to find that most of the Tenax evaporated before I used it.

I now use Tamiya Extra Thin, great stuff. NB There are two different Tamiya Extra Thins. There is Tamiya Extra Thin in a darker green bottle. It doesn't evaporate as quickly as Tenax 7r or Plastruct's Bondene. It's perfect for those places where you need to apply first and then position the part. www.tamiyausa.com/shop/finishing/extra-thin-cement-2/Then there's Tamiya Extra Thin Quick Setting in a lighter green bottle which evaporates extremely quickly, much like Tenax 7r or Bondene. This stuff is perfect for brushing on joints where you want capillary action to pull it in. www.tamiyausa.com/shop/finishing/extra-thin-cement/ |

Never seen it in any of my local shops, and no idea it existed until now. But thanks to Amazon, I'll have some in my hands by the end of the week.  |

It's great stuff. Both of them are actually. Warning, the quick setting is even more harmful than the standard stuff.

My Tenax 7R also evaporated. It's good to know of some good alternatives.
