Abstract
An improved composite material provides surfaces for handling hot glass charges and newly-formed glass articles without detrimental marring or marking of the same. The surface is formed on a relatively smooth metallic substrate by applying a primer coating of a first silicone resin to the substrate, applying a solventless second silicone resin binder coating over the primer, depositing a layer of granular heat-resistant carbonaceous material over the binder and allowing the binder to embed the carbonaceous material, and heat-curing the binder to provide a lubricated durable wear-resistant surface for handling hot glass charges or gobs as well as newly-formed glass articles.
Claims6
As a product by process, a composite material for handling glass charges, newly-formed hot glass articles and the like and comprising a coated metallic substrate formed by applying a primer coating of monomeric/polymeric first silicone resin to said substrate and air-drying the same, applying a coating of solventless curable thermosetting second silicone resin binder over said primer coating, depositing at least one layer of granular heat-resistant solid lubricant carbonaceous material over said binder coating and allowing said binder to wet and embed said granular carbonaceous material to firmly retain the same, and heat-curing said binder into thermoset further-hardened condition to permanently affix said granular carbonaceous material to said substrate.
