摘要

Automotive refinishing operations consist of surface preparation and repainting of motor vehicles subsequent to their initial manufacture. These operations occur in auto-body repair/paint shops, new car dealer repair/paint shops, fleet operator repair/paint shops, production auto-body paint shops, and custom-made car fabrication facilities. Following structural preparation of the automobile, paint and/or coating mixtures are sprayed directly onto the automobile surface using a spray gun. This generic scenario describes methods to estimate the releases of and exposures to non-volatile coating components (pigment, binders, additives) from automotive refinishing spray applications and from the disposal of empty coating containers. As stated in the introductory remarks, releases and exposures resulting from other refinishing and auto-body shop operations such as sanding or curing are not addressed in this scenario. Refinishing shops typically use three types of coatings to paint an automobile: primer, basecoat, and clearcoat. Each coating type performs a specific task in the refinishing process. The primer coating is specifically designed to adhere to the vehicle metal surfaces to protect it from oxidation, the basecoat provides color for the automobile and the clearcoat adheres to the basecoat and provides protection for the basecoat and a high-gloss finish to the surface. Any of these formulations may contain the chemical of interest. Automotive refinishing shops fall under the North American Industry Classification System (NAICS) code 811121. They are comprised of businesses primarily engaged in repairing or painting car, truck, or trailer bodies (1). According to the 2001 County Business Patterns data, 34,786 establishments within the United States performed the tasks outlined in this NAICS code with a total of 221,129 workers.
