The present invention is directed to an improved process for producing substantially pure fluorescein, as well as to substantially pure fluorescein compositions prepared by the process. An insulating coating composition comprises a polyamide-imide resin, which is obtained through a synthetic reaction of isocyanate component with acid component, and a lubricant component, wherein the terminal isocyanate group of the polyamide-imide resin is capped with a blocking agent of higher alcohol having a carbon number of eight or more. Unheated air is flowed over the fuel components to adjust and maintain a desired moisture content of the fuel components to a level that permits cutting of the fuel components without chipping or cracking. Each alert may also have a notification setting defining how the user is to be notified.
