Patent ID: 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.
