Well since the glue does not -dry- (it sets) at all there is no
concern. I would quote you from my bottle but am laid up now and can't
reach it. As to the specific concern. No, 50 degrees is no problem.
The glue will set in a very frew seconds and ready for use in under 30
seconds at least down as far as I have used it which is not much above
freeqing.
