Abstract
A weighing pan for a comparator balance has a surface coated with a polymer lacquer. The coated surface is distinguished by a moderate hardness and increased levels of sliding friction and adhesive friction. By adding anti-static agents, the surface coating can be made sufficiently conductive to avoid electrostatic charges. The coating is resistant to solvents and to the kinds of fluids that are used to perform density determinations.
