Often confused by people not in the know, but very different surfaces. As above, resin bound is a porous system which is floated to leave a smooth surface. It is generally considered a much more decorative surface. Resin bonded is a non-porous system, installed by levelling pure resin on a substrate and broadcasting/scattering aggregate over the top. This obviously leaves a texture and serves as a great anti-slip coating. In fact, the first uses of the surface was for High Friction Surfacing for the roads.
