glues...

[LVZ2881]

between plastruct plastic weld, tenax, epoxy, CA, and liquid cement.....

also, how in the heck do you get tenax to work??

I have a bottle, but everytime i put a brush to it, it doesnt look like anything is on the brush

Tenax is not really an adhesive, it's a solvent that dissolves the plastic and makes the parts fuse together. You don't spread it on the parts like you do with for example tube glue, epoxy or CA, as it will usually dry quicker than you can assemble the parts. Just hold the parts together, brush some Tenax on the joint and let the capillary action do the rest. I haven't tried the Plastruct variety, but I believe that it works the same way.

Just a solvent.

I usually hold the parts together and let it wick in from the brush.

If You can Find it, Faller Super Expert Liquid cement ( ita a German product) is in my opinion is the best out there. its a little pricey at $6.00 for a 25g (about 1.5 fl oz.)but Like I said if you can find it give it a try I think you,ll like it

It depends what you are glueing. Faller is an excellent glue for joining engine blocks or similar assembly. For longer seams and other plastic to plastic where a Liquid Glue is preferred Ambroid Proweld or Plastruct Bondene are the best, A good substitute is Methyl Ethyl Ketone. I only use super glue for metal to plastic and other dissimilar materials like resin. In some cases aan Epoxy can be used. In my my opinion Super Glue will never be as strong as a good Liquid Glue in glueing plastic together. By the way Faller lasts forever, I had a bottle that was about 15 years old that was still good. It's halfway between a Liquid and a Tube Glue in constistency.

Funny that you would say that, I have also got a bottle of Faller that I have had for about 15 years, and I'm still using it now and then. It's still as good as the day I bought it and it seems like there's gallons of glue in that tiny little bottle, but I guess this is because the built-in needle applicator makes it so easy to apply just the tiny amount you need. $6 ain't that bad at all, considering how long it lasts.

For styrene plastics....I use MBS Solvent cement...it welds the plastic together instead of bonding....and I use the Flash CA (green bottle) for resin cast parts

What's goin' on...

I like to use Tenex 7R 90% of the time.

It works best on styrene plastic like older kits and Plastruct/ Evergreen Scale pieces. Tenex will evaporate fast on heavier plastics so heavier amounts is needed . As far as appling the Tenex I use Micro Brushes that are sold in packs at major hobby shops. Just dip the brush in the Tenex then touch the pieces and capillary attraction will draw the solvent into the joint. Another thing to use is a sirringe. In my opinion it doesn't have as strong of a smell as the Plastruct does.

The Plastruct works good w/ the plasic found in late kits and acrylic plastics. That has a strong smell that will linger and it has a longer drying time than the Tenex but usually creates a stronger weld in the heavier plastics.

Super Glue is good to attatch metal pieces to plastic and the heavier glue is good for gap filling.

As far as Epoxy goes I have yet to use that.

Model Master glue is good for pin point applications. Put some on a piece of scrap plastic and use a pin to apply the glue to the part you're attatching.

Good Luck!!!
