    Abstract: A composition includes an elastomer and a ketoximo silane or a ketoxime additive. The ketoximo silane corresponds to Formula I: D-SA—B  (I) where B defined as: where D is selected from a C1 to C60 hydrocarbyl group, or when A is 0 or 1 a hydrogen, or the structure in Formula III; and wherein n and j are independently 1, 2, or 3, m and q are independently 0 or 1, z and t are independently 0 or 1 and (n+m+z) is equal to 3 and (j+q+t) is equal to 3; A is 0 or greater than or equal to 1; R1 and R2 are independently C1 to C60 divalent organic groups and may optionally include O, N S, Si, and/or P heteroatoms with the proviso that when A is 0 either of R1 and R2 may be a chemical bond; R3, R4, R8 and R9 are independently a hydrogen, or a C1 to C60 hydrocarbyl or alkoxy group optionally including O, N, S, Si and/or P; R5 and R6 are independently hydrogen or C1 to C60 hydrocarbyl groups and may optionally include O, N S, Si, and/or P heteroatoms, and may optionally be bonded together to form a cyclic ring; R10 and R11 are independently hydrogen or C1 to C60 hydrocarbyl groups and may optionally include O, N S, Si, and/or P heteroatoms, and may optionally be bonded together to form a cyclic ring.

    Abstract: A flame retardant filler having brominated silica particles, for example, imparts flame retardancy to manufactured articles such as printed circuit boards (PCBs), connectors, and other articles of manufacture that employ thermosetting plastics or thermoplastics. In this example, brominated silica particles serve both as a filler for rheology control (viscosity, flow, etc.) and a flame retardant. In an exemplary application, a PCB laminate stack-up includes conductive planes separated from each other by a dielectric material that includes a flame retardant filler comprised of brominated silica particles. In an exemplary method of synthesizing the brominated silica particles, a monomer having a brominated aromatic functional group is reacted with functionalized silica particles (e.g., isocyanate, vinyl, amine, or epoxy functionalized silica particles). Alternatively, a monomer having a brominated aromatic functional group may be reacted with a silane to produce a brominated alkoxysilane monomer, which is then reacted with the surface of silica particles.

    Abstract: A room temperature-curable electrically conductive fluorosilicone rubber composition comprises: (A) a fluoropolysiloxane capped at the molecular terminals with hydroxyl groups having a viscosity at 25° C. of from 1,000 to 1,000,000 mPa·s; (B) fine silica powder having a BET specific surface area of not less than 50 m2/g; (C) a carbon black; (D) a fibrous carbon allotrope having a graphene structure; and (E) a crosslinking agent. Component (D) is comprised in an amount of not less than 1.5 parts by mass per 100 parts by mass of component (A). The room temperature-curable electrically conductive fluorosilicone rubber composition is cured to form a cured product having both superior post-cure physical strength and electrical conductivity. Also, the room temperature-curable electrically conductive fluorosilicone rubber composition has viscosity that enables superior handling, and provides superior post-cure surface smoothness, solvent resistance, and adhesion.
