I was going to look on the label to see if a chemical ingredient was
available and post it. I buy it in 1 gallon or 5 gallon cans called "roof
asphalt". It comes in runny type for coating large areas or it comes in
thick type for filling gaps or holes. It is very black and sticky and I use
"mineral spirits" if I get any on my hands. I suppose it is the same stuff
used in blacktop and asphalt.

I would guess it is a petroleum derivative. I will look on the cans
tomorrow to see if they give some chemical identity of the ingredients.
