    摘要: A method for photo-hardening a silicone rubber surface, the method comprising a step (A) in which a surface of a molded silicone rubber is irradiated using, for example, a xenon excimer lamp with vacuum ultraviolet light having a wavelength of 200 nm or less at an irradiation energy in the range of 10-3,000 mJ/cm2, thereby forming an oxide layer in the irradiated portion by photooxidation and thus hardening the portion. According to the method, it is possible to harden the surface of the silicon rubber into a wear-resistant surface without causing a change in gloss and while keeping the rubbery feeling intact. It is also possible to improve the oil infiltration resistance of the rubber.

    摘要: An addition reaction-curable silicone emulsion composition containing a water-soluble silane coupling agent (I) and an organopolysiloxane (II) having at least two alkenyl groups in one molecule thereof, where the water-soluble silane coupling agent (I) has at least one group selected from among a succinic anhydride group, a quaternary ammonium group, and a ureido group, and 1 part by mass or more of the water-soluble silane coupling agent (I) is contained relative to 100 parts by mass of the organopolysiloxane (II). This provides: a silicone emulsion composition that gives a cured film adhering well to plastic film substrates regardless of the type, while having suitable release properties regarding adhesives; and a delamination film made by forming a cured film of the silicone emulsion composition.
