Abstract:

Electrically conductive liquid coatings containing carbon blacks are essential in many applications, including primers for automotive plastic parts and coatings for electrostatic dissipation control. This study outlines the important carbon black variables that affect the electrical conductivity of coatings. The analytical properties of the carbon black (e.g., structure, surface area, and volatile content), the carbon black loading, and the dispersion quality all contribute to the conductivity of the cured coating. Proper grade selection and effective incorporation of carbon black are as important as resin selection in developing a conductive coating.
