One of my physics professors was the funniest and best instructor on planet Earth. It’s such an important subject for life.

My physics teacher was a 6'6" 320# Catholic Brother who, at a very young age was on the Manhattan Project team. He also taught my father at the same high school. Brother Gordian would constantly remind me that my dad was the smartest student he ever taught. Then he would say, "what happened to you"? He had this thing he called an H5. Had something to do with the Richter scale. All of us were terrified of this guy. He would slowly prowl up and down the rows of desks and when he got to his intended target, BAM!!!, he would pop someone in the back of the head with an open hand. For me, it was when I got a "C" on a test. For others it would be for screwing around in his class.

Loved that guy. I learned a lot in that class.

The substrate (and the ambient temperature) influence the viscosity of the epoxy you apply to a blank. The warmer the surrounding air and the blank the "runnier" the epoxy, all else being equal. A second (and third, fourth . . .) layer of epoxy will be runnier than the first epoxy layer because the greater area of the naked thread wraps provides more surface tension than additional, unnecessary coatings of epoxy provide.

A higher working temperature effectively makes the epoxy thinner for a brief time, but because a higher temperature also hastens the setting time, the epoxy then becomes thicker more quickly than it would at a lower temperature.
