[SOLVED] What is this black stuff on my PSU coil?

There is some gooey looking black stuff on my coil. I stuck a hairpin inside and it's rock hard.
Here is a video of it:

The PSU is a Super Flower SF-1000F14MP 1000W 80+ Platinum

Solved: Was told that it's epoxy, used to keep the coil wiring together. Can close.
