Inusfficient detail. You need different glues/bonders for different materials and material combos, and for different strain/stress situations.
There is a web site "ThistoThat.com" which has a lot of stuff. On the other hand I tried "plastic" to "plastic" and it did failed to say "Tenax". So it may not have everything there is to have.

This to That:
I have had good results with 2 differant glues for plastic, depending on what you are working on. Testors Model Master liquid glue comes with a thin tube dispenser is good for larger apps such as plastic buildings. Just put the 2 pieces together and run the tube down the inside edge. The full cure drying time is about 8 hours. The other glue I use is Plastruct Pro Weld liquid glue that comes with a brush dispenser. I will use this for smaller aps such as adding detail parts to a loco, or buildings. You can use the brush that comes with the glue or use a small 3-0 brush. The drying time for the Pro Weld is about 2 hours. You have to be very careful with the Pro Weld as it will seep into any small cracks or onto you fingers that will leave a nasty smudge mark on what ever you are working on. Hope this helps as to what you are woking on. You can contact me off list into any other questions

For typical plastic kit (styrene) I like the Proweld too. Tenax is another brand name that works well. I believe both products are just MEK in a convenient small bottle. The brush in the cap is a little coarse for fine work, a small paint brush works better. They are thin enough for capillary action to draw the liquid into joints. The stuff dries fast, so fast it is difficult to assemble parts before the solvent evaporates. It is also very strong. A spill will do bad things to kitchen table tops, dining room table tops, asphalt tile floors, linoleum and many paints. I think formica counter tops will survive a spill, but I wouldn't want to bet the farm on that. A well made joint is nearly as strong as thee original styrene.
