Hi All,
There seem to be many epoxy experts so someone might be able to
answer this odd phenomenom. I use 330 and when I began using it I
weighed it carefully 50/50 on an accurate balance and it usually
didn’t harden but stayed sticky. I now pour it onto wax paper by
eye, and yes I mix thoroughly for at least one minute. The stirrers
I steal (oops borrow) from Starbucks work well with the curved end
cut off) and it always hardens. I measure by eye which can’t
possibly be as accurate as weighing it. Any ideas? Oh yes, and I
don’t add any coloring agent that might inhibit the process.
