Polyurethane Enamel

Q. What is the deference or similarities between Acrylic Polyurethane, Polyurethane Enamel, and Acrylic Polyurethane Enamel?

A. An "enamel" is the general term used to describe a high gloss decorative topcoat. Therefore, we talk about alkyd enamels, acrylic enamels, epoxy enamels, etc.

Polyurethanes come in a variety of formulations; acrylic-polyurethanes, polyester-polyurethanes, polyurethane "oils" and modifications of other resin systems, such as alkyds. I don't know anything about Matthew's Paint, but DuPont's Imron polyurethane is a two-component acrylic polyurethane decorative topcoat. If the Matthew's polyurethane is similarly two-component, then all three of the terms you describe probably have the same meaning.
