When it’s hot, it stinks of hot ABS, and it dissolves in acetone. I’ve read that sometimes budget filament manufacturers will use the same pigment across their whole material range, even if it’s not capable of withstanding the print temperatures of some of them, but it’s ABS+ rather than pure ABS, so it could be full of mystery additives that don’t handle heat well, too.

There’s not much point using it as glue as I’m not going to get through a whole kilo worth of ABS glue, and produce more than enough ABS scraps from test prints and support to always make a colour-matched glue anyway.
