| Résumé : |
Utilizing a naphthenic acid ester as a dispersant, an aqueous conductive carbon black dispersion was produced, which displayed excellent flocculation resistance, increased grinding efficiency, and inherent rheological stability when compared to a dispersion utilizing competitive dispersant or no dispersant at all. The aqueous conductive carbon black dispersion was subsequently formulated into an aqueous conductive automotive primer. The primer exhibited excellent dry film conductivity, rheological stability, and wetting characteristics when applied to plastic substrates. Humidity sensitivity of the primer was greatly reduced over similar primers formulated with competitive surfactant-based carbon black dispersions |
