I am looking for a powder that can be applied by electrostatic spraying that will have a rubber-like finish.

Q. I am looking for a powder that can be applied by electrostatic spraying that will have a rubber-like finish. J.L.

A. The rubber-like surface you describe would be best achieved with a vinyl or PVC coating. Vinyl powder is a thermoplastic product that is usually applied by fluid bed dip, but you should be able to spray it if you set up the gun right. You may need to have a positive charge for that kind of powder. PVC is a liquid that is applied by dip. It also is possible that you could work with a formulator to develop a soft thermoset product.
