  • Publication number: 20200010714
    Abstract: Embodiments herein provide for a waterborne PVDF coating composition, the preparation method and use thereof. The coating composition includes a waterborne polyvinyl fluoride dispersion, a waterborne carboxyl acrylic resin, and a crosslinking agent. The resulting coating gives excellent film performance which is comparative to that of solvent borne PVDF formulations. Meanwhile, the coating composition requires smaller amount of crosslinking agent in the formulation, and lower heating temperature for curing process, as compared with solvent borne PVDF formulations.

  • Patent number: 10289101
    Abstract: A method and system to help control body-shop processing of vehicles, based on timing of interaction with a touch-screen display. In an example implementation, a body shop will be equipped with a computing system including a touch-screen display, with the computing system being configured to manage presentation on the display of graphical representations of job-cards for individual body-shop jobs, such as individual vehicles in for repair. With such an arrangement, body shop personnel could drag and drop job cards from one section to another to indicate transitions of jobs between body-shop processing steps. The computing system will then advantageously make use of data regarding the timing of those drag-and-drop operations as a basis to control body-shop processing, such as be predicting a processing duration of a job currently in process and taking action to modify processing of the job based on the predicted duration for instance.
