Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
109 words
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.
Claim 2
Dependent Claim
109 words
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.
Claim 3
Dependent Claim
74 words
The product by process of claim 1 wherein a second coating of solventless curable thermosetting silicone resin binder is applied on the granular carbonaceous material and heat-cured binder and a second layer of said granular heat-resistant solid lubricant carbonaceous material is deposited over said second binder coating and embedded therein and said binder is heat-cured into thermoset further-hardened condition to permanently affix said second layer of granular carbonaceous material to the heat-cured first coating.
Claim 4
Dependent Claim
34 words
The product by process of claim 1 wherein said binder coating of solventless curable thermosetting silicone resin comprises a clear liquid methoxy functional intermediate silicone resin having an average molecular weight of about 600.
Claim 5
Dependent Claim
32 words
The product by process of claim 1 wherein said carbonaceous material comprises a particulate mixture of activated charcoal and graphite having a particle size ranging from about 10 to 100 U.S. mesh.
Claim 6
Dependent Claim
29 words
The product by process of claim 1 wherein said heat-curing step is performed at a temperature of about 500° to 550° F. for a period of about 11/2 hours.
Claim 7
Dependent Claim
23 words
The product by process of claim 1 wherein said carbonaceous material is selected from the group consisting of graphite, carbon, and activated charcoal.
