Does anyone know where Toluene-free thinner falls on the bad/not-bad scale for nylon products like rope?
A friend asked me because there was an incident where some thinner splashed on his new rope, but I don't know where thinner is on the petrollium-based product range.
Thanks.

Ok. This is a great start. Instead of having to consider the billion different possible constituents of the mystery chemical. We now only need to consider the 999,999,999 other possibilities apart from toluene. 
Without more knowledge of the aggressive mystery chemical it seems prudent to assume that the rope is compromised.

Unfortunately there's not much else on the container... It's a German brand for shoe cement.
Renia (brand)
"Toluene-free thinner, for all RENIA rapid cements (contact cements) like: Colle de Cologne, Vulkofest, top-fit, Ortec, etc."
I'll keep digging for more...

Perhaps you could contact the manufacturer of the rope - they might have more info. Of course, they might very well say to buy a new rope, as that's the least risky thing for them to say. If they say it's not a problem and the rope fails, you could sue them.

This website may help: http://www.coleparmer.com/Chemical-Resistance
You can try to match up the chemicals on the MSDS.

Thanks. Looks like the three main chemicals are rated "excellent" for compatibility with nylon.
Still, if anyone has any further information I'd love to hear about it so I can pass on an informed recommendation to my friend.

In any case, you can heavily soak a piece of webbing or rope in the chemical and mail it off to me and I can pull test it.

It's a mixture of solvents that evaporate readily and don't damage nylon. The rope should be just fine once it's dry. I'd fall on it.
The take-away from this, however, is that someone has to start paying more attention to what they are doing around their climbing gear. No reason to be slopping solvents of any kind around with the rope nearby.

Thanks Mike.

I hardily agree. I think they've learned their lesson but only time will tell.
