They don't list the ingredients on the bottle. I'd have to get hold of an MSDS sheet to be 100% sure, but I believe it's near pure methylene chloride (dichloromethane).

A commenter on a model train forum said "My experience with Tenax has been best summed up with "Spit and water holds together better than that"."

It has always worked well for me on styrene, but it doesn't work like the old style Testor's tube cement of the 70's if there are gaps to be filled. The parts have to fit really well and you let it wick in. If you need to fill gaps, you have to dissolve styrene shavings in it, which worked great on my Maxi V-2 fins when I had a spot or two that didn't fit perfectly.
