Abstract
Polyurethane/polyurea polymers can be electrostatically painted without first being coated with a conductive primer. Disclosed is a process for electrostatically painting polyurethane/polyurea polymers, the process having a step of including a non-volatile metal salt conductivity inducing material. The conductivity of the polymers of the present invention can allow them to be charged with sufficient charge density to permit efficient paint transfer to the polymer surface. Also disclosed is a composition of at least two adjacent layers, one layer being an outer layer of electrostatically applied paint, and the other an inner layer of polyurethane/polyurea polymer.
