Abstract
A solid film lubricant composition for hot glass contacting surfaces of glass handling equipment and metal molds used in manufacturing glass articles. The solid film lubricant composition is a solution of a solvent, graphite, a solvent-soluble, further curable organopolysiloxane, and NaOH to make the solution alkaline. The solution is easily sprayed on hot glass contacting surfaces such as the interior of the molds to form a coating that is curable at room temperature.
