Abstract
An ultraviolet (UV) curable organopolysiloxane composition with excellent workability when applied to a substrate is provided, in which a product obtained by curing the composition has a low dielectric constant. The UV curable organopolysiloxane composition comprises (A) one or more organosiloxane and/or organopolysiloxane having an average of two or more UV reactive functional groups in one molecule, and (B) one or more organosilane, organosiloxane, and/or organopolysiloxane having one UV reactive functional group in one molecule. An organic solvent is not included in the composition. In addition to components (A) and (B), the composition can comprise one or a plurality of additives selected from a group consisting of: (D1) nonionic surfactants not containing a silicon atom and are not acrylic; (D2) nonionic surfactants containing a silicon atom and having an HLB value of 4 or less; and (D3) silicone oils with a viscosity of 90 mPa-s or less at 25° C.
