Hello,
I have a question about Plastic Weld from Plastruct. Is this glue compatible with DBM and Walthers plastic kits? I built the Walthers Deisel Fueling Depot and I have noticed now the parts are just starting to fall off easily. It is like the glue is not holding. I want to buiild some more kits but not sure if I should use this glue again or get something else.
Thank you,
Jeff
It has been mannnnnnny moons, but I recall when I tried it on non Plasticweld plastic, it did not do well.

Jeff,
Plasticweld is designed to bond dissimilar plastics, such as abs to styrene. Bondene, also made by plastruct, is for same plastics like styrene to styrene. I have had great luck with the Testors liquid cement for styrene applications. Chris Nelson
I just tried to use Plasticweld on a repair today. Didn't even haze the plastic. Made the repair with Tenax 7R. Rarely do I use anything but the Tenax on anything anymore.
However, in the past, I have been able to use the Plasticweld on Plastistruct shapes and sheet material without problem.
I personally prefer Tenax but do also use Plastruct plastic weld (the orange label) & Bondene (the white label) Plastic Weld is a general purpose cement so it may not work well on what your using.. Bondene is made specifically for styrene and ABS plastics. both work well depending on the application. I have found a few things about Plastruct glue though that you should be aware of. A: It doesn't seem to have a very long shelf life, once it's opened it seems you have to seal the bottle immediately after you apply the glue. There are times when gluing several parts all at the same time lets say a row of windows in a structure that I just keep dipping the glue brush in it until I'm done and then put the cap back on, which brings me to the second issue. there are times you may get a little bit of paint on the glue brush and if you did it back in the bottle the glue doesn't seem to respond well to contamination. I am just guess as I sucked at chemistry that there must be something in the paint that reacts with the glue. The only advantage I can say I see of using Plastruct over Tenax is if you put glue on both surfaces and give it a second to flash up the bond seems to happen immediately. I had to choose one over the other I would definitely choose Tenax hands down.
Thank you everyone,
I picked up some Testors Liquid cement and Tenax. I used both last night and they worked great.
I bought a can of MEK (methyl ethyl ketone) from Ace Hardware. It comes in a quart can, and it's a lot cheaper than either Testors or Tenax. A quart can costs about the same as those little bottles. I have a couple of bottles of Tenax. When I run out, I just refill the bottles with a small metal funnel. It works great on just about any plastic. Just be sure to use it in a well ventilated area.
