Photocurable adhesion-promoting compositions containing organic titanates and/or organic zirconates and partially reacted alkoxysilanes and the use of the photocurable adhesion-promoting compositions to provide adhesion between metal substrates and an overlying radiation-cured sealant are disclosed.

An object of the present invention is to provide a sealing method using a cover film where a problem of odor is not likely to occur and quick drying properties and sealability are high.

The sealing method according to the present invention is a sealing method that is performed using at least a cover film and a sealing solvent, the cover film including a polymer layer provided on a transparent support, in which the sealing solvent is a solvent including at least one kind selected from the group consisting of an ester, an alcohol, a ketone, an ether, and an aromatic hydrocarbon, in a case where the sealing solvent is an ester, an alcohol, a ketone, or an ether, a boiling point of the sealing solvent is 80° C. to 170° C., and in a case where the sealing solvent is an aromatic hydrocarbon, a boiling point of the sealing solvent is 150° C. to 170° C.

A non-curable thermally conductive silicone grease composition includes: A. 100 parts by mass of a non-curable silicone oil with a kinematic viscosity of 50 to 10000 mm.sup.2/s at 40° C.; and B. 105 to 500 parts by mass of thermally conductive particles with respect to 100 parts by mass of the component A. The thermally conductive particles contain the following: B1. 50 to 300 parts by mass of irregularly-shaped alumina with a median particle size of 0.1 to 1 .Math.m, in which a part or all of the alumina is surface treated; B2. 5 to 50 parts by mass of plate-like boron nitride with a median particle size of 0.1 to 10 .Math.m; and B3. 50 to 150 parts by mass of aggregated boron nitride with a median particle size of 20 to 70 .Math.m. The B3/B2 blending ratio is 2 to 20. Thus, the thermally conductive silicone grease composition has a high thermal conductivity, but still has a relatively low specific gravity, and also has a viscosity for good workability and good coating properties.
