Shouldn't be a problem, but to be sure just pull the blade and clean it.

I do not believe you will have a problem. I have the unfortunate first-hand experience (pun intended) of having a blade embedded in a standard cartridge on my bookshelf here in the shop. Thought about making a clock out of it or something. I've also tested the dado cartridge with a hidden staple. The spring is pretty stout and drives up fast and with significant force. In both of my experiences, the blade was well-buried in the aluminum block. Power also gets cut to the motor right away, so the blade is only going in with the momentum it is carrying with it. I can't imagine your gummy polyurethane would provide sufficient lubrication to make that much of a difference in the speed of capture, should it fire.
I'd be more worried about the messy gunk on the blade or in the cabinet than I would about it stopping safely.
Math is tough. Let's go shopping!

Are you asking whether or not the polyurethane has enough electrical conductivity to trip the SS sensor (like cutting some wet pressure-treated wood might)?

Either that or increase the electrical resistance, possibly not allowing the saw to “see” flesh contact?

I bet running little oak across that blade will help clean it up. I think that when cutting/ripping pine is a problem due to sap pockets.
