That was going to be my next question - working time and
fractional amounts - thanks for anticipating..


I've done quite a bit of potting for electronics with
room-temperature catalysts. In winter the pot-life would
be about 40 minutes and it would take overnight to
cure. On a hot summer's day don't bother... the pot
life would be seconds, and I have actually seen a batch
go off in mid-pour. If you have to do it now choose a
chilly night and do it in the early morning. After
pouring do a light waft with the hair drier which will
make it slightly runny, before it starts to cross-link.

I used it on a hot summers day. Working time about 15 minutes. Hard in a
couple of hours. Rock hard after a day. Roughly the same as '30 minute
epoxy'
