Been very happy with "Same Stuff" from Micromart

This was equivalent to Ambroid "Pro-Weld", which was my other go to plastic cement.  Tenax and Pro-Weld are the only plastic cements that I have been able to use in the Micromart "Touch and Flow" applicators.  Everything else clogs them up after one use.

Tenax 7R alternative - Plastic Magic 10s

Tenax 7R had these attributes:

- Glues styrene, ABS, and acrylic plastics
- Bonds quickly,a in like 10 seconds
- Nonflammable
- Odorless, non-sniffable
- Evaporates extremely fast

On that last item, I always found once I broke the seal on the bottle, it would evaporate in a couple weeks even with the cap on. Very annoying, the stuff was not cheap.


My replacement: Deluxe Materials Plastic Magic 10s:

- Glues styrene, ABS, and acrylic plastics
- Bonds quickly, in like 10 seconds
- Nonflammable
- Odorless, non-sniffable
- Evaporation from the bottle almost non-existant (hooray)

You can find Deluxe Materials Plastic Magic 10s from hobby shops online, or you can get a bottle from Amazon here for ~$10 with free shipping:

Everything Tenax 7r was, only better.

I Agree But 10 Sec ??

Joe- I got a bottle after you recommended this a ways back in another similar thread. Pretty much concur with all your bullet points except I've never had it bond in 10 seconds.  Not that you can do much wrong in applying the glue to a joint, but am I missing something?  It seems like 1 minute (or longer), not 10 seconds when I use it.  I apply it sparingly to, so I don't think its because I use too much.  Like it though, just tired of holding parts together longer than I had to with Tenax.  

Thanks,

Craig

This is the current Tenax 7R

At least as far as I'm concerned. Been using it for a few years now. 

BTW I have not had the "evaporating" bottle problem that Tenax always had.

Tenex was TOO fast

With Tenex I was seldom able to put the solvent on the part then place the part.  Most of the time it would have evaporated before I got the parts together.  Quite often applying the solvent to a joint wouldn't work either because it would have evaporated by the time the brush got to the joint.  I have a nearly full bottle because I prefer other cements.

Also, whoever thought a tall skinny bottle was a good idea should have their head examined.  Similar complaint with labels that wrap all the way around the bottle so I can't see the liquid level.

For a long time I refilled my old Tester's square bottles with MEK.  Will try ethyl acetate if I ever buy in bulk and refill bottles.

Now I am with Joe, on Plastic Magic.  Squat bottle that does not tip over.  Can see liquid level through the shoulders of the bottle.  Brush in the bottle is small enough to be useful.

Tamiya, Mig, Humbrol, no worries

It's not the first time this kind of post is open.

Don't understand such worries when speaking about plastic glue, same with model paint

There are numerous excellent plastic glue on the market.

I avoid to play the sorcerer with glue, like using MEK or any other apprenticed chimist mixture glue; because  with a professional background all these mixtures are dangerous for your health

Price is not an argument since a little bottle of Mig or Tamiya or Humbrol glue  is enough for more of  one year construction; I build around one or two model a week, so ….

I have used Humbrol glue for all my plastic models for years some have more than 40 years and never seen any unglued join and everybody say it's not a convincing glue

When Humbrol begun  to be difficult to find, I have used Tamiya glue, perfect plastic glue, exist in three kind, soft and thin and relatively thick

I have also used Faller plastic glue and now some Mig glue.

I brush lightly these glue with a brush, more than enough to have a strong bond

For other plastic out of the styrene family, I use professionnal glue from Loctite or Sikaflex specified for this kind of plastic.

98 % of the offered plastic kit are in styrene so don't worry; only the small run offer use these out of family styrene plastic

Never see any troubles in any of my plastic kit, same with the numerous scratchbuild models done with Evergreen plastic all glued with Humbrol, Tamiya or Mig

And in a other aspect, I build many craftsman kit in wood or laser kit;  I use rarely wood glue for them but only Loctite gel superglue, the five minutes drying time is a must and bond are extremly strong on wood parts, this way I did'nt waste time for waiting drying time; Georges Sellios of FSM use the same way for his magnificient model

So don't worry be happy …..

On the run whith my Maclau River RR in Nscale

Tamiya Extra Thin- Sort of...

Short Answer- For years Tenax 7R was my favorite styrene glue. But, when it became hard to find I moved to Tamiya Extra Thin Cement (green cap) and is now my go to cement. However, I recently switched to Tamiya Air Brush cleaner which is, for all practical purposes, the same formula but much cheaper.

Lou in California.

Longer Short Answer- A few months ago I read in another model forum* that Tamiya Airbrush Cleaner (87089) was almost the same formula as Extra Thin but a lot less expensive.  I was a bit skeptical so looked up the EU Safety Data Sheet.  Extra Thin is 50% Butyl Acetate and 50% Acetone and Airbrush Cleaner is 51% Butyl Acetate and 49% Acetone- close enough for me.  I tried it out and they both perform the same. On Amazon Extra Thin is about 12¢ per ML and AB Cleaner is about 4¢ per ML.  I do put the AB cleaner into the Extra Thin bottle as I like the brush in the lid.  I do keep a bottle of Tamiya "regular" Cement (orange cap) around for when I want a longer set up time.

*Yes, I do speak scale modeling languages other than "Model Railroadese" LOL

Spill "eliminators"

Not elegant but works for me. The secret ingredient is the never drying children's clay that I've used for 30+ years.

I have used the Flexifile

I have used the Flexifile product and it was good.  Shortly after that I got a gallon of MEK and have been filling the small bottles of Pro-Weld that I had saved.  That was a couple of years ago and I haven’t put a dent in the gallon.
