TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The composition comprises filler combination (in weight%) (50-90, preferably 70-85), reaction product (A) (0.1-25 weight parts based on 100 weight parts of epoxy resin), and optionally an organosilane. The nitrogen-containing base is an amine, a polyamine or an imidazole. The filler combination comprises graphite powder in the form of synthetic graphite with an average particle diameter of 0.1-500 microns, preferably 50-100 microns.    TECHNOLOGY FOCUS - POLYMERS - Preferred Materials: The epoxy resin is an epoxy phenol novolak or an epoxy cresol novolak. The microgel is a copolymer of unsaturated carboxylic acid(s) and polyfunctional crosslinker(s). The unsaturated carboxylic acid is (meth)acrylic acid. The polyfunctional crosslinker is a polyfunctional (meth)acrylate of an aliphatic, cycloaliphatic or aromatic polyol, an addition product of (meth)acrylic acid and a polyglycidyl compound, an addition product of (meth)acrylic acid and glycidyl (meth)acrylate, alkenyl (meth)acrylate, a dialkenylcyclohexane or dialkenylbenzene, preferably ethylene glycol di(meth)acrylate, propylene glycol di(meth)acrylate, 1,4-butanediol di(meth)acrylate, polyethylene glycol di(meth)acrylate, polypropylene glycol di(meth)acrylate, 1,1,1-trimethylolpropane tri(meth)acrylate, bisphenol A diglycidyl ether di(meth)acrylate, allyl (meth)acrylate, divinylcyclohexane or divinylbenzene. SPECIFIC COMPOUNDS - The nitrogen-containing base is 2-phenylimidazole, 2-isopropylimidazole, 2-dodecylimidazole, 2-heptadecylimidazole, 2-hardness ethylimidazole (sic), or 2-ethyl-4-methylimidazole.
