Abstract: Conductive curable compositions contain a free radical polymerizable monomer, oligomer or polymer (i); an organoborane amine complex (ii), and an electrically or thermally conductive filler (iii). The conductive curable compositions can also contain an amine reactive compound having amine reactive groups (iv); and (v) a component capable of generating a gas when mixed with a compound bearing active hydrogen and a catalyst. The electrically conductive curable compositions can be used in composite articles of manufacture in which substrates are coated or bonded together with the composition and cured; and as electrically conductive rubbers, electrically conductive tapes, electrically conductive adhesives, electrically conductive foams, and electrically conductive pressure sensitive adhesives.

Abstract: A phase change composition comprises: a matrix comprising a silicone-organic block copolymer, and a thermally conductive filler. The composition can be used as a thermal interface material in electronic devices. The composition is formulated to have any desired phase change temperature.

Abstract: A silicone composition for preparing a silicone pressure sensitive adhesive, the composition comprising (A) 20 to 55 parts by weight of a polydiorganosiloxane containing an average of at least two silicon-bonded alkenyl groups per molecule; (B) 45 to 80 parts by weight of an organopolysiloxane resin consisting essentially of R33 SiO1/2 units and SiO4/2 units, wherein the total amount of components (A) and (B) is 100 parts by weight; (C) an organohydrogenpolysiloxane having an average of at least two silicon-bonded hydrogen atoms per molecule in an amount sufficient to cure the composition; (D) 25 to 200 parts by weight of a silica filler having an average surface area less than 25 m2/g; and (E) a catalytic amount of a hydrosilylation catalyst. Each R3 is independently selected from the group consisting of monovalent hydrocarbon and monovalent halogenated hydrocarbon groups. The mole ratio of R33SiO1/2 units to SiO4/2 units in the organopolysiloxane resin is from 0.6:1 to 1.
