TECHNOLOGY FOCUS - CERAMICS AND GLASS - Preferred Material: The inorganic material is metals, glass, ceramics, cement, slate, marble, granite or mortar, each of which may be coated with a metal.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The organosiloxane compound has fluorine atom has perfluoroalkyl, perfluoroxyalkyl, perfluoroalkylene or perfluoroxyalkylene group and at least two SiH bonds per molecule. The organic solvent is hydrochlorofluorocarbon solvents, hydrofluoroether solvents, hydrofluorocarbon solvents or perfluorofluorocarbon solvents.    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The perfluoro polyether backbone of the linear perfluoro polyether compound is of structure -(CaF2aO)q- or structure (I).q=20-600;X=-CH2-, -CH2O-, -CH2OCH2- or -Y-NR1-CO-;Y=Me or o-, m-, or p-dimethylsilylphenylene group of structure (Ia) or (Ib);R1=H, Me, Ph or allyl group;X'=-CH2-, -OCH2-, -CH2OCH2 or -CO-NR2-Y'-;Y'=Me or an 0-, m-, or p-dimethylsilylphenylene;R2=H, Me, Ph or allyl group;p=0 or 1;r=2-6;m, n=0-600;n+m=20-600.Preferred Material: The organic material is acrylic resins, phenolic resins, epoxy resins, polycarbonate resins, polybutylene terephthalate resins, polyamide resins, polyacetal resins, modified polyphenylene ether resins, polysulfone resins, polyether sulfone resins, polyphenylene sulfide resins, polyarylate resins, polyamideimide resins, polyetherimide resins, polyether ether ketone resins, polyimide resins or liquid crystalline polymers. Preferred Method: The applied primer composition is cured and dried. A heat curable fluorinated elastomer composition or a heat curable fluorinated gel composition is applied on the dried or cured primer composition. The applied heat curable fluorinated elastomer or gel composition is cured. Preferred Composition: The heat curable fluorinated elastomer composition comprises polymer having at least two alkenyl groups per molecule and a perfluoro polyether backbone, a compound having at least two SiH bonds per molecule and platinum group catalyst. It also comprises organic peroxide. EXAMPLE - A primer composition was prepared except that the organosiloxane of was added in an amount of 80.00 pbw, HFE-7200 was added in an amount of 1100 pbw, and 2 pbw of 3,3', 4,4'-benzophenone tetracarboxylic acid dianhydride fine powder was further added. It was applied by a brush on test pieces. The applied primer was dried at room temperature for 5 minutes, and then heated to 180degreesC for 15 minutes. On the cured primer surface, a mold was placed to make a bead. In the mold, the fluorinated elastomer composition was injected and heated at 150degreesC for 30 minutes. The article thus obtained was subjected to measurement of adhesion strength with a 90degrees peeling tester.
