  • Patent number: 8053517
    Abstract: This invention pertains to neutralized silicone elastomer dispersions and methods for making neutralized silicone elastomer dispersions. This invention also pertains to compositions comprising the neutralized silicone elastomer and an acid reactive compound. The silicone elastomer dispersion are neutralized typically by blending the silicone elastomer dispersion with a base such as sodium bicarbonate or by adding a basic neutralizing agent to one or more of the raw materials used to make the silicone elastomer dispersion and removing the basic neutralizing agent by filtration or any other suitable means.

  • Patent number: 6971163
    Abstract: The attachment of an electrical component to an electrical termination on a component-carrying substrate by a solder bump technique of a thermally curable adhesive composition for encapsulating purposes is described which comprises a thermosetting polymer and a chemical cross-linking agent which has fluxing properties but which is unreactive or of severely restricted reactivity with the polymer without the action of heat and/or catalyst. The composition is to be thermally curable when heated to soldering temperatures in a reaction which is catalyzable merely by metal oxide fluxed from metal surfaces by cross-linking agent then dissolved in the thermosetting polymer.
