Anyone else ever burnt a hole in their kecks, from a drop of superglue
dripping on them ? Heat build up from fineness of threads or chemical
make-up of the cloth?




When I've spilled a drop of superglue on my pants,it just leaves a dark
spot that is hard and inflexible,and that doesn't wash out.

HTP can burst into flames when spilled on dirty fabrics.

Once when repairing the PCB runners on an ABS monitor case, that a
previous
repairer had mucked up with solvent glue, I'd superglued most of the
shattered fragments of ABS back in - but a lot was just crumbs.

What I used to fill the gaps, was cigarette ash and superglue, a plug of
ash
soaked in superglue is like granite - I noticed that the effect of ash on
superglue was that it set hard instantly, and produced a lot of heat in
doing so!



If the cloth had been touching skin I would have got a burn. Don;t know what
temp it got to or whether it was smoke or steam rising from the patch. It
turned into a burnt hole with a surround of metal-hard ex-fabric around.
Probably a volume to surface area effect. Cigarette papers are paassed
through a multi EHT discharge process to create millions? of micro pores in
the paper to assist "draw".
Don't know what my kecks were made from, as label is washed out , but
presumably polyster and cotton fibres.
