  • Patent number: 11180635
    Abstract: Compositions of matter that are useful in the preparation of plastics and paints. These compositions contain a large number of silanol groups bonded to the silicon atoms that provide water solubility and/or disperseability of such materials in aqueous solutions. In addition, these compositions contain organofunctional groups that are antimicrobial in nature. These compositions, when coupled with plastics and paints, provide antimicrobial properties to such plastics and paints as well as adhesion properties.

  • Patent number: 11045780
    Abstract: A method of encapsulating particulate materials. The method of encapsulating particulate materials may be used to multi coat a coated thermoplastic particle. The method includes providing an amount of acidified water in an amount to hydrolyze a pre-determined amount of alkoxysilane. A particulate thermoplastic material is dispersed within the acidified water. Once dispersed, an amount of alkoxysilane having a pre-determined formula is added and an amount of time is allowed to pass thereby allowing the alkoxysilane to hydrolyze and build a particle having a pre-determined particle size. Once the particle with pre-determined particle size has been obtained, the particles may be combined with alkoxysilane having a pre-determined formula and an amount of time is allowed to pass thereby allowing the alkoxysilane to hydrolyze and build a particle having a pre-determined particle size. This provides an encapsulated particulate material having one or more coatings thereon.
