Chemical composition of possible adhesive, or: What's in this tube?

Good morning. While cleaning my bathroom, I found a tiny little white metal foil tube, like a tiny toothpaste tube. It measures about 2" in length. It has a white paper label that reads:

Contents: MEK…40% Toluene…10% Acetone 10% Polyurethane…30% Ethyl Acetate…10%.

MADE IN CHINA

I don’t remember ever seeing this tube before, so I don’t know where it came from (besides China). Based on the chemicals I’m guessing it’s some kind of adhesive, probably a clear glue for bonding plastics or wood, but if anyone has any knowledge about this chemical compound, please chime in!

Thanks.

You are correct. The 30% polyurethane content is glue for woodworking. The other indgedients are solvents.
Avoid inhallation of vapors. Use with adequate ventilation, preferably outdoors when practical.

your MEK is an abbreviation for Methyl Ethyl Ketone, as already noted a solvent.
