  • Patent number: 5034075
    Abstract: The present invention discloses a method for encapsulating and containment of asbestos covered workpieces such as power equipment material. A resin and catalyst mix is applied to the asbestos covered surface. Glass is applied with the resin or after the resin. The surface is then compacted by brushing or rolling, to provide consistent application and to remove air bubbles. In certain instances, this material is applied to a chopped roving which is then applied to the surface prior to compaction. In the preferred embodiment, a chopper gun is used to apply the resin, catalyst, and glass mixture.
