  • Patent number: 3989852
    Abstract: A process for encapsulation is provided. Generally, the materials involved are those which tend to lose at least part of their original properties upon exposure to auto-oxidative, thermal, or humid conditions. The process comprises constituting the material to be encapsulated in or as a viscid medium and dispersing the medium as particulates into an atmosphere containing an agitated quantity of a powdered, sorbent, film-forming agent. The dispersed particulates must have a tacky surface. The powdered agent adheres to this tacky surface and absorbs sufficient liquid to gel the coated particulates and to form a continuous, substantially non-crackable and dry encapsulating film around each of the particulates.
