Epoxy and Polyurethane compounds are thermoset plastics. Epoxy and Polyurethane substrates bond well to each other as long as the surfaces are clean and slightly abraded..
Likewise, does epoxy resin stick to polyurethane?
The epoxy seal coat will not stick to an oil based stain or oil based paint. The polyurethane will cover that and allow the epoxy to stick. This does not take the place of the epoxy seal coat as that is still necessary. You will paint the epoxy on your surface just as you paint on a wall.

Hereof, is polyurethane the same as epoxy?
Generally, a polyurethane floor coating is highly flexible and elastic, while epoxy flooring is harder and more brittle. This makes polyurethane coatings more resistant to scratches and similar damage and is why you'll often find urethane resin floors in heavy traffic areas – such as multi-storey car parks.
Does polyurethane bond to metal?
Urethane rubbers that exude an oil (such as PMC-121® WET or PMC®-780 WET) will not bond permanently to any metal. You can increase your chance of a secure bond between urethane rubber and metal by: Etching or sanding the metal surface. Clean surface with solvent (acetone) and let dry.
