  • Publication number: 20210206971
    Abstract: A silicone composite for high temperature insulation applications is disclosed. The composite is formed of a silicone and a thermally decomposable inorganic filler which are compounded together. The compounded material is then injection molded, overmolded, compression molded, cast, laminated, extruded, or dispensed. When the silicone composite is exposed to a high temperature, it forms an inorganic composite and maintains its insulating properties and dimensional stability.

  • Patent number: 10246599
    Abstract: A silver paste ink composition comprises a plurality of first particles comprising silver; a polymer binder; a carrier solvent; and a plurality of second particles comprising silver. The second particles are nanoparticles that are different than the first silver particles, the amount of second particles in the ink composition being sufficient to impart a first color to the uncured ink composition, the first color being different than the color of the same ink composition without the nanoparticles. The silver nanoparticles have a property of causing a change in the color of the ink composition when the ink composition is cured.
