  • Publication number: 20190276684
    Abstract: A reactive hot-melt silicone filling container is disclosed. The reactive hot-melt silicone filling container includes a crosslinkable silicone composition. The crosslinkable silicone composition comprises: (A) an alkenyl group-bonded organopolysiloxane including at least a branched organopolysiloxane having an alkenyl group and a softening point of 50° C. or higher; (B) an organopolysiloxane having at least two silicon atom-bonded hydrogen atoms per molecule; and (C) a hydrosilylation reaction catalyst. The crosslinkable silicone composition is filled into a container and the container is heated so as to crosslink the crosslinkable silicone composition in the B-stage state, to form reactive hot-melt silicone that is non-fluid at 25° C. and has a melt viscosity of 5,000 Pa·s or lower at 120° C. The reactive hot-melt silicone filling container can provide reactive hot-melt silicone having excellent gap filling properties upon heating.

  • Patent number: 7056129
    Abstract: An anisotropically electroconductive adhesive film is characterized by containing an electroconductive elastomer that traverses the thickness of the adhesive film and is insulated in the plane of the adhesive film comprising electrically insulating elastomer, and both the electroconductive elastomer and the electrically insulating elastomer have a modulus of elasticity at 150° C. that is no greater than 100 MPa. A method for producing the anisotropically electroconductive adhesive film is characterized by forming through holes across the thickness of the adhesive film comprising electrically insulating elastomer, thereafter filling the through holes with an electroconductive elastomer composition, and curing the electroconductive elastomer composition to form the electroconductive elastomer after filling the through holes.
