    摘要: The adhesive bonding of a silicone rubber to a metal surface can be very much improved by the use of the inventive primer composition, in particular, with respect to the heat resistance and anti-oil resistance of the adhesion. The inventive primer composition comprises (a) a substantially linear diorganopolysiloxane of gum-like consistency free from aliphatic unsaturation, (b) an organopolysiloxane with the organic group/silicon atom molar ratio of 1.9 to 2.3 and having a limited amount of vinyl groups directly bonded to the silicon atoms and a viscosity of 5 to 10,000 centistokes at 25.degree. C., (c) an organopolysiloxane resin with the molar ratio of organic groups/silicon atoms of 0.5 to 1.7, (d) an organosilane compound such as vinyl trimethoxysilane or vinyl tris(2-methoxyethoxy) silane, (e) a finely divided silica filler, (f) an organic peroxide and (g) a curing agent for silicone resins, all in limited weight proportions.

    摘要: A curable silicone composition based on an organopolysiloxane having a cyclotrisiloxane structure quickly cures by brief heating or ultraviolet exposure. It further contains an acid, acid generator, base or base generator or an oniom salt photo-initiator as a curing agent. The cured product has release property from adhesive substance which remains unchanged with the lapse of time and good mold release properties, and thus provides a lightly releasable cured film. The composition is widely used as adhesive tape backing agents, mold release agents, protective coating agents, water and oil repellent agents, and paint base.
