Abstract
Abstract Composition and method for protecting extended planar surfaces from undue-build-up of static charge comprising an aqueous solution of e.g. sodium tripolyphosphate buffered with a mixture of baking soda and washing said against aggressive corrosion of the treated surface by the polyphosphate, applied per se or in intimate mixture with conventional surface protective films such as waxes and paints.
