TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The solvent comprises ketone, alcohol and/or ester solvent (preferably methyl isobutyl ketone, ethyl acetate, cellosolve acetate, sorbitol acetate, 3,5,5-trimethyl-3-cyclohexenene-1-one, cyclohexene-1-one, butyl cellulose acetate, ethanol, methanol and/or isopropanol). The curing agent comprises an amine. The amine curing agent is selected from N,N'-dicinnamylidene-1,6-hexane, hexamethylene diamine carbamate, and/or ethylene diamine carbamate (preferably N,N'-dicinnamylidene-1,6-hexane). The metallic oxide reduction-agent particulate comprises MgO of 1-30 parts per 100 parts by weight of the fluoroelastomer particulate. The inert particulate is selected from calcium carbonate, carbon black, graphite, fumed silica and/or kaolin (preferably carbon black). The solvent comprises a blend of 3,5,5-trimethyl-cyclohexene-1-one (20 wt.%), cyclohexenone (20 wt.%), and cellosolve acetate. The carbon black is of 35 parts per 100 parts by weight of the fluoroelastomer particulate, the polytetrafluorinated ethylene particulate is of 5 parts per 100 parts by weight of the fluoroelastomer particulate, the N,N'-dicinnamylidene-1,6-hexane is of 8 parts per 100 parts by weight of the fluoroelastomer particulate, and the MgO is of 20 parts per 100 parts by weight of the fluoroelastomer particulate.    TECHNOLOGY FOCUS - POLYMERS - Preferred Admixture: The admixture further comprises (d); (e) polytetrafluorinated ethylene particulate of less than 75 parts per 100 parts by weight of the fluoroelastomer particulate, the polytetrafluorinated ethylene particulate having a mean particle size of 10-50 microns; (f) wax particulate of 0.05-5 parts per 100 parts by weight of the fluoroelastomer particulate; and (g) solvent to provide an admixture viscosity of 10000-500000 centipoises. The admixture further comprises microspheres of 0.5-20 (preferably 8) parts per 100 parts by weight of the fluoroelastomer particulate. EXAMPLE - A gasket admixture comprising (parts): Viton B (RTM: FKM terpolymer (fluoroelastomer particulate)) (100), MT990 (RTM: Carbon Black) (30), Maglite Y (RTM: magnesium oxide (MgO)) (10), wax (1.2) and polytetrafluorinated ethylene (PTFE) (50), was prepared. The above ingredients were combined. The agglomerate was then blended into the sheet form compound and then cut into chunks. A coating was prepared by dissolving and mixing the pieces into butyl cellulose acetate solvent by the weight ratio of 3:5 (solids versus solvent). N,N'-Dicinnamylidene-1,6-hexane curing agent was mixed in at a weight ratio of 1:23 over the above polymer solution just before applying the coating. A viscosity was measured on the final coating at around 100000 centipoises by Brookfield viscometer. The coating was applied selectively onto a graphite substrate to make a gasket for a fuel cell. The screen printed part then was dried and cured, at 90 and 390 degrees C respectively, each for 15 minutes. The coating was used for sealing and for electrical insulation. Testing showed that the FKM coating sealed air under 10 lb/in2 load and provided sufficient insulation function with a 150 micrometer thick cured film.
