  • Publication number: 20230392011
    Abstract: A liquid silicone resin composition is provided. The liquid silicone resin composition comprises (A) a polysiloxane, (B) a polyether alcohol compound, and optionally (C) an aminosilicon compound. The polysiloxane (A) comprises an MQ resin, which is dispersed in and optionally functionalized with the polyether alcohol compound (B), and which may also optionally have amino functionality. The liquid silicone resin composition comprises a tunable viscosity, which may range at 25° C. from 100 to 800,000 cps. A method of preparing the liquid silicone resin is also provided. The method comprises combining together a solid silicone resin and the polyether alcohol compound (B) to give a mixture comprising the polysiloxane (A) and the polyether alcohol compound (B), and liquefying the mixture, thereby preparing the liquid silicone resin composition. The method may optionally include the aminosilicon compound (C).

  • Patent number: 11390747
    Abstract: A composition for forming a silicone elastomer is disclosed. The composition comprises: A) a linear organopolysiloxane having at least two silicon-bonded ethylenically unsaturated groups per molecule; B) a linear organohydrogensiloxane having at least two silicon-bonded hydrogen atoms per molecule; C) at least one cross-linker; and D) a hydrosilylation catalyst. The cross-linker C) is selected from the group consisting of: C1) an organopolysiloxane having at least three silicon-bonded ethylenically unsaturated groups per molecule; and C2) an organopolysiloxane having at least three silicon-bonded hydrogen atoms per molecule. At least one of the silicon-bonded ethylenically unsaturated groups of component C1) has a lower reactivity relative to the silicon-bonded ethylenically unsaturated groups of component A). Moreover, at least one of the silicon-bonded hydrogen atoms of component C2) has a lower reactivity relative to the silicon-bonded hydrogen atoms of component B).
