I am not sure what the coating is made from, but when it burns it has a real acrid odor and accidentally breathing in the fumes will give you a good coughing fit for awhile...much like burning Teflon does.
In regards to burning off the coating, it only took 2-3 minutes. I also checked the can afterwards when it cooled off and there was no trace of the coating left.
