Abstract

Polyurethane/polyurea polymers can be electrostatically painted without first being coated with a conductive primer. Disclosed is an improvement in a process for electrostatically painting polyurethane/polyurea polymers, the improvement being to prepare the polymer from a formulation including a non-volatile metal salt conductivity inducing material. The polymers painted by the process of the present invention can have physical properties and aesthetic properties substantially similar to those of otherwise identical polymers prepared without the non-volatile metal salt conductivity inducing materials of the present invention. The increased conductivity of the polymers 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 layers, one layer being an outer layer of electrostatically applied paint, and the other an inner layer of polyurethane/polyurea polymer.
