ADDITION REACTION-CURABLE SILICONE RUBBER COMPOSITION FOR HEAT-RESISTANT APPLICATIONS AND SILICONE ADHESIVE

摘要

PROBLEM TO BE SOLVED: To provide an addition reaction-curable silicone rubber composition for heat-resistant applications and a silicone adhesive capable of maintaining stable rubber physical properties for a long period of time even if it is subjected to a heat test.;SOLUTION: The addition reaction-curable silicone rubber composition comprises, as essential ingredients, (A) 100 pts. mass of a diorganopolysiloxane having at least two alkenyl groups in a molecule, (B) an organohydrogenpolysiloxane having at least two hydrogen atoms in a molecule which are coupled to silicon atoms, wherein the number of hydrogen atoms coupled to the silicon atoms in a molecule of the organohydrogenpolysiloxane corresponds to 0.1-5.0 moles per one mole of the alkenyl groups in the organopolysiloxane of the (A) component, (C) a catalytic amount of a hydrosilylation reaction catalyst, and (D) 5-300 pts. mass of γ-Fe₂O₃ (maghemite) which is a magnetic iron oxide as a heat-resistance enhancer.;COPYRIGHT: (C)2006,JPO&NCIPI
