Abstract: A composition contains filler particles dispersed in a matrix material, wherein the matrix material includes: (a) a first polyorganosiloxane that comprises an average of 2 or more succinic anhydride groups per molecule; and (b) a second polyorganosiloxane other than the first polyorganosiloxane; wherein the filler particles are present at a concentration in a range of 15 to 80 volume-percent based on composition volume and wherein the first polyorganosiloxane is present at a concentration sufficient to provide succinic anhydride groups at a concentration of 0.30 to 200 micromoles per gram of matrix material.

Abstract: Thermally conductive compositions include a blocked isocyanate prepolymer composition containing an isocyanate prepolymer blocked with one or more of alkylphenol or alkenylphenol; and an amine composition containing: one or more polyetheramines, and one or more catalysts selected from a group consisting of carboxylate salts, tertiary amines, amidines, guanidines, and diazabicyclo compounds; and a thermally conductive filler present at a percent by weight of the thermally conductive composition (wt%) in a range of 60 wt% to 98 wt%; wherein the thermally conductive composition cures at a temperature in the range of 18oC to 35oC when the blocked isocyanate prepolymer composition and the amine composition are mixed. Methods include preparing a thermally conductive gap filler prepared by combining a blocked isocyanate prepolymer composition and an amine composition, and curing the resulting thermally conductive composition, such as at room temperature.

Abstract: An article includes a laminate material with an aerogel layer and a polysiloxane layer distinct from the aerogel layer and in contact with the aerogel layer either directly or through an adhesive that is in direct contact with both the aerogel layer and the polysiloxane layer; where the polysiloxane layer comprises a polysiloxane and greater than 5 weight-percent and 95 weight-percent or less based on polysiloxane layer weight of fire retarding additives selected from a group consisting of metal hydroxides, mixed metal hydroxides, hydrated metal salts, and any combinations thereof dispersed throughout the polysiloxane layer.
